Passing query string parameters to Visual Web Parts?

Does anyone know how to get the parameters from a query string to a Visual Web Part?
Dan Marth

Hi,
you can read the query string parameter from the code behind using:
Request.QueryString["YourParam"];
You can also use Javascript or jQuery:

How to pass query string parameters in list ?

Hi,
I have a "Links list" it contains the columns "Empname", "Description" and "Susped/resume" .Here Admin enters the records. When admin enter 'suspend' in "suspend/resume" column it will navigate to "suspend
page" similarly if enter 'resume' it will navigate to resume page.
So How I have to set the suspend/resume column by using query string parameter? (dont use hyperlink)
(We are completely developing my project by using out of box )
Appreciate if any one help.
Thank you.

Hi,
It will be easier for others to research on your requirement if you can provide more details about your requirement.
What is the reason of not using a hyperlink field type? As with hyperlink, we can navigate to other pages easily.
If you want to use other field type, we will need to write some code(JavaScript) to meet your requirement.

Using Query String Parameters with Session Scoped bean

I would like to pass query string parameters from a product page (user clicks on a specific product commandLink) that is request scope to a details page that is session scoped.
The problem is that the session scoped page only handles the first request. If you view the details of a product and then navigate back to the product page and choose another product ... the details page will not handle the new query string parameters and display the details for the first product chosen.
Is there a way to make the session scoped bean recognize the query string parameters past the first request?

I was able to replicate this problem with a very simple app that performs a redirection... just like the real app. Here's the simple app that I put together:
From request scope page:
<f:view>
         <h:form>
           <h:commandButton value="Link 1" action="#{reqbean.Link1}"/>
           <br/><br/>
          <h:commandButton value="Link 2" action="#{reqbean.Link2}"/>
        </h:form>
       </f:view>
From request scope bean:
public String Link1() throws IOException
    // Add event code here...
    //redirect the user
    FacesContext.getCurrentInstance().getExternalContext().redirect("untitled2.jspx?p=1");
    return null;
public String Link2() throws IOException
    // Add event code here...
    //redirect the user
    FacesContext.getCurrentInstance().getExternalContext().redirect("untitled2.jspx?p=2");
    return null;
}At this point... I put a println in the constructor of the session scoped bean because this is where I want to get the query string params. The constructor only gets called the first time a redirect is performed.

How to display alert message box in sharepoint 2013 visual web part?

Hi,
I am developing a visual web part which submits data to the list. Once it submits the data, I should convey to the user that the data has been submitted successfully.
I tried using clientScript.RegisterStartUpScript etc, but, none of them are working. It is not throwing any error , but pop up is not getting displayed.
Preferrably, I would like to call this alert message from cs page, because, I will be using it in several places.
Please help me.!
Thanks in advance.
Hepsi

Hepsi,
Step 1. On the Page_Load - This way you can pass parameters. Try this
btn.Attributes.Add(
"onclick", string.Format("return openSPPopup('{0}?{1}={2}', '{3}')", YourPage_URL, var1_Name, value1, Param1_PopupTitle));
Step 2 : Javascript function
function openSPPopup(navigateURL, popUptitle) {
var options = {
width: popupWidth,
height: popupHeight,
url: navigateURL,
scroll: 0
SP.UI.ModalDialog.showModalDialog(options);
return false;
Step 3: The popup close code (in .cs file) – I do it this way as it is just close dialog code and easy to write.
protected void btnClose_Click(object sender, EventArgs e)
{ this.Page.ClientScript.RegisterStartupScript(this.GetType(), "PopupScript", "SP.UI.ModalDialog.commonModalDialogClose(1, 1);", true);

How to customize the SharePoint 2010 search query string parameters

Hi All,
I am trying to redirect default SharePoint search to a custom search results page.
I modified the Search Settings to redirect to the URL that I want.
But my custom search page takes different query string parameters to provide the results.
Eg: SharePoint search passes k=search term when we perform a search. But my custom page needs
test=search term
I would like to pass 'test' instead of 'k' as a query string. Is this possible?
Thanks
Carol

There is no way out of the box to change it. You could always write your own control that passes the value or inherit from SearchBoxEx web part (if you are using a search center) to pass a different value. Query String Filter web part won't
help you here I am afraid. However, wouldn't it be easier just to change your code to take the value that SharePoint passes you?

Visual Web Part Value not Selecting in Page Redirection

Hi..
I have a Visual Web Part having DropDown Controls and adding Webpart in 3 Web Part Pages .. When we redirect from 1 page to another, the selected dropdown values are not coming in 2nd and 3rd page..
Ravindranath

You have added visual web part in three different pages, drop down value will not be selected when you redirect to page 2 or page 3 because they are separate pages and a separate web parts added on each page. Each page has a separate page life cycle.
You can only set dropdown value by passing query string parameter.

Returning Name and Username from People Picker Field in Visual Web Part

Dear All
I am creating a visual web part that displays a list that I have created in SharePoint. One of the fields in the list is a People & Groups column type (People Picker) called 'Presented by'. In my web part, I would like to display the username and
the name of the person who has been 'picked' in this field. However, my using <%# Eval("Presented by") %> only displays their name. How do I get this field to also return their username?
Many thanks for your help
Daniel

You ca use this code:- change it according to your need
int requestForUserID = 0;
string requestForUserLoginName = string.Empty;
string requestForUserName = string.Empty;
string userAccount = peoplePickerEmployee.CommaSeparatedAccounts;
string[] UsersSeperated = peEmployeeOnBehalf.CommaSeparatedAccounts.Split(',');
foreach (string user in UsersSeperated)
SPContext.Current.Web.EnsureUser(user);
SPUser spUser = SPContext.Current.Web.SiteUsers[user];
requestForUserID = spUser.ID;
requestForUserLoginName = spUser.LoginName;
requestForUserName = spUser.Name;

web-part to another web-part. How to achieve this scenario?

Hi Sam,
What you can do is using SPD create a data view webpart which excepts query string value as filters as shown in the below article
http://madanbhintade.wordpress.com/2012/01/08/sharepoint2010dataviewwebpart/
http://sharepoint.stackexchange.com/questions/55184/how-to-filter-dataview-webpart-dvwp-from-query-string
Then When you click on the pie charts particualr section perform a post back by appending the required query string paramter to the same page on which your webpart exist

Access denied error while adding visual web part

i am trying to create visual web part using client side code in SharePoint 2013.
i am able to deploy my web part but when I try to add it on a page it says " Access denied. You do not have permission to perform this action or access this resource" and when i try to debug it it shows exception: "The remote server returned
an error: (500) Internal Server Error."
Following is the code:
protected void Page_Load(object sender, EventArgs e)
var ClientContext = new ClientContext("http://172.20.30.100:1111/");
//SP.ClientContext.get_current();
Web web = ClientContext.Web;
ClientContext.Load<Web>(web);
ClientContext.ExecuteQuery();
var BU = web.Title;
ListCollection ListColl = web.Lists;
List list = ListColl.GetByTitle("LNT_Testimonial");
CamlQuery CmlQry = new CamlQuery();
CmlQry.ViewXml = @"<View>
<Query>
<Where>
<Eq>
<FieldRef Name='BU' />
<Value Type='Text'>" + BU + @"</Value>
</Eq>
</Where>
</Query>
<RowLimit>1</RowLimit>
</View>";
Microsoft.SharePoint.Client.ListItemCollection items = list.GetItems(CmlQry);
ClientContext.Load<ListCollection>(ListColl);
ClientContext.Load<List>(list);
ClientContext.Load<Microsoft.SharePoint.Client.ListItemCollection>(items);
ClientContext.ExecuteQuery();
//var testimonial = items.FieldValues["testimonial"];
foreach (Microsoft.SharePoint.Client.ListItem item in items)
var testimonial = item.FieldValues["testimonial"];
regards, Ritesh Anand

I'm not sure if you are trying to create visual webpart or doing something else? As I understand from your code, maybe, you are trying to access list item. If you have access to the server (on-premise), you can check the ULS log for details of the error.
Is it access denied or 'internal server errror'. If it's internal server error then more details can be found in SharePoint ULS log. About reporting service, not sure if it's related to your original question. Please try to use a single post to focus on single
problem.

UiXML and query string parameters

Is there a simple way to access a query string parameter within the destination page?
Example:
- in my source page I have something like:
<link text="My page destination"
destination="page?param1=value1" />
What I want is to be able to acces directly to the param1 within page.uix without handling events or writing any kind of java code.
I have tried to use ctrl:page, ctrl:eventResult or ctrl:servletRequest without success (thought it was not the right thing to do but gave it a try anyway).
As i understand (?) the doc query string parameters are event parameters:
- does it mean we can only deal with query string parameters in an event handler?
Oscar

Hi Oscar -
As i understand (?) the doc query string parameters are event parameters:
- does it mean we can only deal with query string parameters in an event handler? Right. The UIX Controller allows you to pass data to a new page using URL parameters in one of two ways: as event parameters - in which case you need to have a corresponding event handler - or as page properties. So, the built-in data providers that are supported by the UIX Controller (ctrl:page, ctrl:eventResult) are designed for supporting these two mechanisms.
If you do not want to write an event handler, then you could consider using page properties to pass your parameters. The following link shows how to use the pageURL bound value to construct a destination which includes a single page property:
<link text="Go to target page" xmlns="http://xmlns.oracle.com/uix/ui">
<boundAttribute name="destination">
<pageURL name="targetPage" xmlns="http://xmlns.oracle.com/uix/controller">
<properties>
<property key="prop1" value="value1"/>
</properties>
</pageURL>
</boundAttribute>
</link>
And the following sample shows how to bind to the same property:
<styledText data:text="prop1@ctrl:page"/>

Create a Site Definition file with Visual Web part in Visual Studio

I tried to create a site definition file in Visual Studio 2013 and SharePoint 2013 by following the MSDN tutorial:
Walkthrough: Create a Basic Site Definition Project. Near the end, I added a virtual web part control to the site definition and registered MyWebPartControls in the site definition's default ASPX page as written in the MSDN tutorial:
Unfortunately, IntelliSense doesn't show any MyWebPartControls: tags, and VisualWebPart1 is highlighted with a warning “Element 'SMWebPart3' is not a known element. This can
occur if there is a compilation error in the Web site, or the web.config file is missing.”
Since it’s a warning, I went ahead to build and deploy the solution. However, when I used the site definition template to create a subsite, it returned a parser error:
Unknown server tag 'MyWebPartControls:TestSiteDef1.VisualWebPart1'
I spent half day researching and debugging, and finally solved the problem. The issue is on the registration line:
<%@ Register Tagprefix="MyWebPartControls" Namespace="TestSiteDef.VisualWebPart1" Assembly="$SharePoint.Project.AssemblyFullName$" %>
The $SharePoint.Project.AssemblyFullName$ is a replaceable parameter to provide values for SharePoint solution items whose actual values are not known at design time. Unfortunately, it does not find the right assembly name during the deployment. It should
be replaced by the Assembly’s Strong Name. Here is how I fixed the problem step by step:
In Solution Explorer, open the package node and double click Package.package
Click Manifest tab in the Package.package.
Copy the full assembly name in the package’s manifest. It may be similar like this:
Assembly="TestSiteDef,
Version=1.0.0.0, Culture=neutral, PublicKeyToken=a300f1f2da8ae976"
Back to the site definition’s default.aspx page, replace the
Assembly="$SharePoint.Project.AssemblyFullName"
in the registration line with the copied text:
Assembly="TestSiteDef,
Version=1.0.0.0, Culture=neutral, PublicKeyToken=a300f1f2da8ae976"
Change the Namespace from
Namespace="TestSiteDef.VisualWebPart1"
to
Namespace="TestSiteDef".
The line to register the web part in a site definition file will look like this:
<%@
Register
Tagprefix="MyWebPartControls"
Namespace="TestSiteDef "
Assembly="TestSiteDef, Version=1.0.0.0,
Culture=neutral, PublicKeyToken=a300f1f2da8ae976"
%>
Clean, build and deploy the solution. It works like charm. (Note: the warning message on visual web part may still exist, but you can ignore it).

Assuming your .ascx.vb file is inheriting from the web part class, you can add the custom properties in the same manor (language syntax aside).
Be sure to use the attributes to correctly identify and scope the properties. (see:
http://www.sbrickey.com/Tech/Blog/Post/SharePoint_Attributes_for_Web_Part_properties)
