Files access report from List View Web Part

Hi,
I have a list,inside the list there are some folders and inside the folders there are some files.
This list has been added to the aspx page as a list view web part.
Now our requirement is to generate report on monthly basis of logged in user who accessed folders/files from the webpart.
Is this possible through OOB/customisation please let me know.
Regards,
Sudheer

Event Receiver to get folder Names from List View Web Part

Hi,
We have a requirement i.e.
On one of the page,there are some folders on the list view web part.
Now through event receiver i should pick the folder names from list view web part and
update the same in the list.
If that names already exists in the list then we should leave without updating,if not we have to add folder name in the list.
Please share your ideas regarding the same.
Regards,
Naga Sudheer M
Thanks & Regards, Sudheer

Hello,
LVWP is just for displaying content of site so you need to associate your event receiver with actual list/library. You can create ItemAdded event receiver to check existing folder and create new if not existing. "sk2014" links are good to start.

Cannot create mysites from powershell: Original XSLT List View Web Part not found

I have a bizarre problem in my SharePoint 2013 farm. This does not occur in my test farm, only in the farm we were going to go live with.
I'm on windows Server 2012, SQLServer 2012 SP1, SharePoint 2013 April CU. 1 appserver/centraladmin server, 2 web servers.
When I log into our mysitehost and click newsfeed, it will create a mysite (even though first it displays "we are sorry there was a problem creating your site")
But from powershell, whether I use $UserProfile.CreatePersonalSite() or New-SPSite, I get the following error:
Original XSLT List View Web Part not found
So far I've only found one other person with this:
http://social.msdn.microsoft.com/Forums/sharepoint/en-US/2503e42c-e114-4e89-8e00-89fe70f0b154/cannot-create-sharepoint-mysite-programmatically
This is a brand new farm, created with the same scripts I created my test farm with, and same version of SharePoint. Only the service accounts are different. (Farm account has admin on the servers right now since I was setting up profile service).
Some other errors from the same correlation ID that look related:
It can't seem to find the listemplate 101
And something looks wrong with the MySiteDocumentLibrary feature
I have tried the following:
1. run psconfig.exe on each server
2. install-spfeature -AllExistingFeatures
3. looped through the directory under Features and for each called Install-SPFeature $dirname -Force
4. uninstalled and reinstalled MySiteDocumentLibrary feature
5. blew away the whole farm (removed all servers from farm, deleted all databases) and recreated it.
6. tried creating the UPA from the CentralAdmin gui.
The only real difference I can think of between the working farm and non working farm is, I installed the working farm using RTM, then as they came out added the March PU and April CU. For this farm I installed RTM and March and April, and then ran my build
farm script.
I am at a loss. What do I need to do, re-install the binaries? That's all I can think of. What I love is that our test / POC system worked fine, and now 2 weeks before go-live I'm seeing errors on the production servers I've never seen before. Using the
same scripts no less.

I've had other problems in this farm: the bug where when you add Administrators to a Search Service via the Manage Service Applications page, it removes the SPSearchDBAdmin role from the search service process account. That one did not happen in the other farm.
At least other people have that one and I could just use the farm admin instead (still troublng of course).

Ok,
Here is the problem:
When creating a mysite from powershell or script, apparently you can ONLY do this from a wfe (or a server running Microsoft SharePoint Foundation Web Application in services on server).
You CANNOT create mysites from script on your appserver if it is not also a Web Application Server. I confirmed the same is true in my test farm. I guess I was always running most of these scripts on the webserver.
I searched all over and cannot find this documented anywhere.
Who do I contact to have Microsoft document this?
It's Thursday morning, I've been working non stop since Saturday morning so you don't have to :)

Missing views dropdown on list view web part.

I asked this before, and it got moved to "admin" with no replies. I really need to know this. I think it may be appropriate for design and customization, because I think that's what the solution may require. It doesn't appear to be an "admin" issue.
Any help will be gratefully received. I am very frustrated by this. The "View:" dropdown list on the right side of the list view web part for my document libraries is not available. The truly weird thing is that in a few cases, it is there, but I can't tell any difference between those web parts or DLs and the ones without the views drop-down. I have defined several public views for each document library. There are no "closed" web parts on the page (which was one suggestion I got).
I can't figure out why the views menu sometimes appears and sometimes does not, when there appears to be no way to control it. Can anyone enlighten me or suggest how I can make it appear? My users are threatening to demand a separate web part for each view (there are hundreds). I may have trouble using SPD on the client's site.

That works if the Web Part was Closed, but does not help if the user deleted the Web Part.
After some digging around in SharePoint Designer and in SharePoint itself, I have a solution for restoring the View dropdown after the out-of-the-box List View Web Part has been deleted. This solution can be accomplished without SharePoint Designer if you are working with a library, but to clean out the views from a list, you will need SharePoint Designer. I am doing this in MOSS 2007 SP1, but it should work for WSS 3.0 as well.
For this example, I am using a document library called Public Documents and my View is allitems.aspx, but this should work for any list or library.
Here are the steps for bringing back the View dropdown:
1.       Navigate to the list or library that is missing the View dropdown
2.       Go to Site Actions > Edit Page > Add a Web Part . In the Lists and Libraries section, check the box next to the Public Documents library and click the Add button.
3.       Within the new Web Part, go to edit > Modify Shared Web Part and change the Toolbar Type to “Full Toolbar”. Click the OK button.
4.       Click the link to Exit Edit Mode and you should have the Full Toolbar for the list/library displayed, but it is still missing the View dropdown menu.
5.       Go to Settings > Create View .
6.       Choose Standard View .
7.       Name the view, check the “Make this the default view” box, select the columns to include, and click the OK button.
8.       Voila, the View dropdown menu is back on the site.
9.       To completely clean it up, for a list, open in SharePoint Designer and delete the allitems.aspx view from the Forms folder. For a library, you can go to the Actions menu and select Open with Windows Explorer . Open the Forms folder (you may need to show hidden files to see this folder) and delete the allitems.aspx view. If you do not have access to SharePoint Designer and you are working in a list, you will need to delete the link on the Quick Launch and add again to point to your new view name.
10.   If the View you deleted was the default for the list or library, it may remove the link from the Quick Launch. It can be added again by going to View All Site Content , selecting the appropriate list or library, going into its Settings menu, and modifying the Title, description and navigation settings to show on the Quick Launch.

Row limit in declarative list view web part

Hi,
Imagine you are in a scenario where you develop a custom web template or a site definition. Page Layouts with web part zones are being provisioned and out of them, decoratively web part pages are being created and populated with web parts. So something like:
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<Module Name="XXXProjectPages" Url="$Resources:osrvcore,List_Pages_UrlName;" Path="" SetupPath="FEATURES\XXX_Intranet_PMO_PageLayouts\">

<File Url="FullPageLayout\XXXFullPageLayout.aspx" Name="Default.aspx" Type="GhostableInLibrary" IgnoreIfAlreadyExists="FALSE" ReplaceContent="TRUE" Level="Published">
<Property Name="Title" Value="Team & Collaboration" />
<Property Name="ContentType" Value="$Resources:cmscore,contenttype_page_name;" />
<Property Name="PublishingPageLayout" Value="~SiteCollection/_catalogs/masterpage/XXXFullPageLayout.aspx, ~SiteCollection/_catalogs/masterpage/XXXFullPageLayout.aspx" />

<View List="Lists/Announcements" BaseViewID="102" WebPartZoneID="wpZone1" WebPartOrder="2">
<![CDATA[
<WebPart xmlns="http://schemas.microsoft.com/WebPart/v2">
<Assembly>Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c</Assembly>
<TypeName>Microsoft.SharePoint.WebPartPages.ListViewWebPart</TypeName>
<Title>Latest News</Title>
<FrameType>TitleBarOnly</FrameType>
</WebPart>
]]>
</View>
For simplicity, let's assume that we are working with instances of OOB list definitions, such as Announcements or Document Library. So far so good. And now the question...
In my understanding if you want to do something as simple as limiting the number of items returned, or specifying a custom view criteria (filter/sorting/grouping, whatever) or just remove the toolbar, you have to go as far as provisioning an ENTIRE LIST
DEFINITION, defining your custom View in it (which declares the toolbar type, row limit and View) and then reference this new View by its BaseViewID. Is that correct?
Is there really no other, simpler way, of 'provisioning' and referencing a new view, to an existing list instance, along with the
Module -> File -> View element? I see a couple of logical options:
1) I would imagine such metadata could be stored in the web part and not the actual list. i.e. the web parts sends a CAML query to the list, based on the View metadata stored in it.
2) As we know, when you Edit page and configure the View for a List View Web Part on the page, that view is stored as a new hidden view in the actual list (i.e. if you have two list view web parts that reference that list, you will have two additional hidden
views). Then why can't we provision such (hidden) view along with the List View WebPart when we declare it and create the page? It could be created on first access of the page, or during the page
provisioning.
Another option could be the XmlDefinition property of the XsltListViewWebPart, but
apparently it is being ignored. I have also tried using the 'CustomSchema' property of the ListInstance, but it totally makes no sense because:
a) You cannot define more than one view in it, i.e. you have to override the OOB view that comes with the definition (lol?!)
b) You are supposed to overwrite the entire list definition, instead of simply upgrading parts of it
So, let me elaborate: if I want to have a <View> (ListViewWebPart) in my Page and this view to have some custom criteria, I have to provision an entire List Definition, is that correct? This is crazy.

Hi Hristo,
According to your description, my understanding is that you want to know if you can use <view> tag in the list view web part to define the row limit of list view web part.
Per my knowledge, you can define rowlimit element in the view element for list view web part directly not necessary to modify the entire list definition.
View Element:
http://msdn.microsoft.com/en-us/library/office/ms438338(v=office.15).aspx
Also, if you want to do more customization, you can still orverride the xslt.

List View Web Part anonymous users paging is broken

Hi I checked that list view web part do not work for anonymous users with paging. wanted to check if its known bug or there is some intention to keep it like that.
Rohit Pasrija

Hi,
According to your description, there is an issue that if the paging is configured for a list view web part, it will be broken for anonymous users.
I tried to reproduce this issue with the steps below, however, all work without issue.
1. Enable anonymous access in Web Application level;
2. Enable anonymous access in site collection level;
3. By default, the permission settings of a list inherit the permissions from its parents, that’s say, anonymous access also enabled in the current list, “Anonymous
Users” can “View Items”;
4. Set paging for the “AllItems” view, add this list as a web part into a page, the paging works as expected for anonymous users.
I suggest you create a new Web Application and configure to enable anonymous access following the steps above to see if the issue still exists.
Thanks

Display Calendar View in List View Web Part

We have a list and a calendar view of the list. I wanted to display the calendar view of the list in a List View Web Part in another page in the site.
When I select the 'Calendar View' from the Views drop-down - it does not work.
Please can you help.

Hi Aritra,
Is there some errors on your environment? So, you can have two workaround to do it.
You can use SharePoint designer to add an empty data view source on your page ,then select the page.
Use
Page viewer web part on your page, then put your calendar view web part page URL into your PVWP.
Thanks,

Items to display in list view web part not showing the items setup

Hi, I have the following issue. I have a list view web part, but the web part is showing more items that the ones setup in the: Number of items to display in list view web part for this view.
It is because that works when using datasheet view and not a normal view? Is there any technical documentation from Microsoft supporting this?

thank you for your answer. It is interesting that the mobile view with the items to show in the mobile view doesn't work in the webpart, but it works when you are using datasheet view, but if you uncheck to activate the mobile view, then, the webpart doesn't
show information, so, it works partially because one part works and not the other.

SharePoint 2010 List View Web Part not showing for read-only users?

Hello all,
I have List View Webparts on my Blank Web Part page, and it's not showing for Read-Only users.
Is this intended by Microsoft or is it a bug?
Thank you!

Hi,
According to your post, my understanding is that the read only user could not see the list view web part.
Per my knowledge, the issue may be cause that the user do not have the proper permission for the list.
1. Check whether the user can access the list.
2. Check whether the user can view all the items instead of partial items in the list.
3. Check whether there are some fields refer to other lists or terms, especially the lookup field or managed metadata filed.
If that is the case, make sure the user can access the lookup list.
Thanks,
Jason

ECT List View Web Part displaying incorrect data when View Item

I have a External Content Type which pulls data from a stored procedure. The stored procedure has 1 parameter - the users logon id. The data retrieved is a list of meetings with start date time, end date time, location, subject, etc. From this ECT there
is an External List which displays all data correctly.
There is 2 pages within the site and its subsites that have list view web parts which display a subset of the info from the external list. When the user clicks a specific meeting to display the complete info on the meeting, the wrong information is displayed,
it always displays the info for the 1st meeting in the list. So, I displayed the BDC Identity field on the list and this field is identical for all the rows since the key for the ECT is the username and hence not unique.
I've spent all day trying to finding a way to resolve this and have come up empty. I've tried to find a way to make the BDC Identity field to be unique, using Business Data View web part, Data View web part, and nothing.
The user needs to be able to click the My Meetings url header on the above pages to see a full list of their meetings so I need the external list. Any ideas how to make the BDC Identity field unique or how to get the View Item on the List View web part to
work correctly?

Sorry, I do not understand what you mean.
I resolved the non unique BDC Identity problem by simply adding the row # to the Username in the stored procedure so the BDC Identity fields on the list records are now unique (although they're really long ie. __bk44003500070057003700560027000200140037003700f600360096001600470056003300,
__bk44003500070057003700560027000200140037003700f600360096001600470056004300 etc). Not sure how it generates the BDC Identity?
I still see the same behaviour when you select a meeting to display the details. It always displays the 1st record in the list.
I added code to the DispForm to display the ID when the page loads and the BDC Identity from the record and verfied that they do match.
I can add another parameter to the stored procedure and just return the row # in that field. What do you mean by make the identifire as Identity in operations?

XSLT List View Web Part Error when Using Group By

I have a Tasks List created a tasks list in SharePoint. The Tasks (normal OOTB template) list works fine in the normal view, however, I have created an XSLT ListView Web Part that points to this tasks list. When I set the web part to display
a view with a "Group By" rule, it returns an error:
"Attempted to use an object that has ceased to exist. (Exception from HRESULT:
0x80030102 (STG_E_REVERTED))
The list has just over 1000 items and the threshold is set to 5000, I have tried indexing the column that I am "grouping by" just in case and that has not worked.
Has anyone experienced this issue before? If so, what steps can be done to display the XSLT List View Web Part properly?

Thank you for the response. I tried the above link and it didn't seem to solve the issue; in fact, when I clicked on Common Control Tasks there wasn't any Data View Tasks such Filter and Sort & Group.
Perhaps some more information would shed light on a solution. I created a list template including content of the task list in question. I was able to display the new list in an XSLT List View Web part with grouping enabled. However, I noticed that
the "Related Content" column was completely empty (it was there, it just had no data in each row). What is the source of this Related Content? I know it is a system column that appears when Workflows generate the item in the list but could it be the
reason for the Web part being unable to display with groupings?

XSLT List View Web part with Inline Editing changing value for one field changes the other lookup field

Hi
It's a bit of a weird one. In an XSLT List View web part when Inline editing is enabled if I change the date column, it changes the lookup field column as well. This behavior only occurs if the lookup list has more than 20 entries. Below 20 and we are
OK.
Let me explain by example:
MileStones List - Having more than 20 items
Tasks List - having a lookup to the Title field from MileStones list. Also having a due date field.
Simple web part page with one XSLT List View web part for Tasks having inline editing enabled.
When I edit the first record's due date and press enter (which saves the changes and moves onto next record) and change the due date on second record without even touching the MileStone field. Press enter to commit changes and you see the milestone changing
on first record!
The wierd thing is that if the MileStone list has less than 20 items all works as expected.
Any pointers will be appreciated
Thanks

Hi,
This is a known limitation when working with complex fields like Lookup field.
A workaround is that we can avoid using the inline edit feature when there are
complex fields in a list.
You can take a look at this KB from Microsoft Support to get more details:

Have JQuery for List View web part, But Full Text Not Visible

I have a list view web part on a page with which, I've edited the view the way I need which includes grouping.
Inside IE's Developer tools, I can see the structure (TD and then an anchor tag linking to document) and see the class SharePoint uses for that TD. BUT - when I view the source for the page, none of the actual text in the created view shows up at all!
What I need to do is to wrap the text inside that TD with more html tags, along with adding a left padding. Adding the padding to the CSS file actually works fine.
The problem is, that when I add the JQuery to wrap everything in the TD the way I need it, since it technically hasn't been rendered yet, even with a document ready function around it, the JQuery never does what it is supposed to do.
here's the JQuery:
$('td.ms-vb').each(function() {
$(this).find( 'a' ).wrap(
$('<ul style="padding:0px;margin:0px;;">
<li style="list-style-type:disc;color:white"></li></ul>') );
I know the JQuery code works because I've tried it on a plain HTML page. The problem is the way the List View web part renders the output. since it's not available on the screen, the JQuery does not work.
I really need to do this without any programming, since this type of interface appears many times throughout the site.
Any ideas on how to accomplish this (get the HTML to show in 'view source' so I can apply the JQuery)?

(bump)
anyone?

How do I remove the grouping headings in my list view web part?

I don't have access to SharePoint Designer and so far, that is all I can find that people are saying to use. I understand and know how to edit the HTML in SharePoint, just don't know what code to put in and where exactly to put it so that the Document
Library List View web part is grouped how I want, but doesn't actually show the group titles. Any help would be greatly appreciated. Thank you!

Hi,
I understand that you want to hide list view group headers, based on your description, I can suggest as follow:
Add this code to a Content Editor Web Part (CEWP) in the list view. Adding a CEWP in a SharePoint 2010 list view will unfortunately remove the list view selector.
<script type="text/javascript" language="javascript">
_spBodyOnLoadFunctionNames.push("HideHeaders");
function HideHeaders()
var elements = getElementsByClassName(document, "td", "ms-gb");
var elem;
for(var i=0;i<elements.length;i++)
elem = elements[i];
elem.childNodes[3].style.display = "none";
elem.removeChild(elem.childNodes[4]);
elements = getElementsByClassName(document, "td", "ms-gb2");
for(var i=0;i<elements.length;i++)
elem = elements[i];
elem.childNodes[3].style.display = "none";
elem.removeChild(elem.childNodes[4]);
elements = getElementsByClassName(document, "tr", "ms-viewheadertr");
for(var i=0;i<elements.length;i++)
elem = elements[i];
elem.style.display = "none";

Updating List View Web Part property in page

I have a List View web part (In the page > Add web part > App > document library name). I need to update the TitleUrl property of this web part through C# code.
The SaveChanges() method below works for my visual web parts, but not for the List view webpart. I get an error saying: Exception has been thrown by the target of an invocation
webpartManager = myPage.GetLimitedWebPartManager(System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared);webPart.TitleUrl = titleURL;webpartManager.SaveChanges(webPart);
I did a casting as below
XsltListViewWebPart listViewWebPart = (XsltListViewWebPart)webPart;listViewWebPart.TitleUrl = titleURL;webpartManager.SaveChanges(listViewWebPart);
(Please note that casting to ListViewWebpart instead of the XsltListViewWebpart gives a invalid cast exception, which is the reason why I cast it to XsltListViewWebpart)
But I get the error at SaveChanges() method.
An exception of type 'System.Reflection.TargetInvocationException' occurred in Microsoft.SharePoint.dll but was not handled in user code
The error description is as below

Tried casting back as below
webpartManager.SaveChanges((System.Web.UI.WebControls.WebParts.WebPart)listViewWebPart)
but still the error at SaveChange() is there.
AllowUnsafeUpdates is set to true within this block and code runs in elevated privileges.

Hi Ahamed,
According to your description, there is an issue when you try to update the TitleUrl property of a List View Web Part.
For a better troubleshooting, I suggest you do as the followings:
1. Debug your code step by step and make sure every object and variable is valid.
2. Here is a code snippet about update web part property programmatically:
SPWeb web = SPContext.Current.Web;
SPFile file = web.GetFile(HttpContext.Current.Request.Url.ToString());
SPLimitedWebPartManager manager = file.GetLimitedWebPartManager(PersonalizationScope.User);
System.Web.UI.WebControls.WebParts.WebPart webPart = manager.WebParts[this.ID];
((UpdateMeWebPart)webPart).Message = “Test”;
try
web.AllowUnsafeUpdates = true;
manager.SaveChanges(webPart);
finally
web.AllowUnsafeUpdates = false;
Here is a detailed article for your reference:
