PAging in Asp Repeater control in Visual Webpart
hi
i am trying to create a visual webpart in which i am getting 100 items from the list and showing it on to the page using ASP:Repeater control now i've to apply paging on the Repeater control,can anyone tell me how do i apply paging in Asp.Net Repeater control.
Hi,
There's no built-in pagination in the Repeater control, you can achieve pagination in the Repeater control by creating another Repeater control for pages and use PagedDataSource as it's source.
Here is a blog with the code for your reference:

How to apply pagination to data bind to asp:Repeater control using Camel Query.
Hi All,
I am having a <asp:Repeater> control to which i bind the data from share point list.
I want to apply pagination to that data which is bind to Repeater. I am using CAMEL query to get data from list.
How can i apply the pagination to this data fetch by camel which is bined to Repeater control.
Thanks
amolHi,
From your description, you might want to use CAML to query the needed items from a SharePoint list, then use a Repeater control to bind to these data with paging allowed.
If so, here is a solution like this: Use
CAML to query a collection of items and save them into a
DataTable object. Then use the PagedDataSource object to achieve the paging for us and associate it to a
Repeater control.
Here are two links will provide more details:

Perform CRUD operation on List using Gridview control (SharePoint Visual webpart)
Hi Friends,
I have SharePoint Visual webpart and I want to perform CRUD operation on SharePoint list using Gridview control.
Is there any other way to implement it , please suggest me the solution approach.
Thanks,
Digambar KashidIs there any specific reason you dont want to use Out Of the Box list CRUD operation? Anyways, if you want to use custom approach I think SPGridView is good approach.
There are some samples available for what you are trying to achieve.

I wanted to use ajax controls in visual webpart for sharepoint 2013 so i followed steps.
1-I cut this snippet (see below) from <head></head> Section and paste in <body></body> Section for my master page since it's a requirement for SharePoint 2013 ajax functionality.

in <controls>
<add tagPrefix="ajax" namespace="AjaxControlToolkit" assembly="AjaxControlToolkit, Version=4.1.7.1213, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e" />

Hi there,
I am new to this Flex 2 technology, and am wondering if I can
have paging in my application.
I have an application with a repeater control and a custom
mxml component within the repeater. The datasource is an XML
generated by a PHP script and I also use HTTPService.
The data get's really large and thinking of fitting paging
capability to the repeater. I have googled it but seems like paging
only been done in datagrid but not repeater. So does anyone know if
paging can be done in repeater? If there is example, would be much
appreciated.
Thanks

Enter some keys and values in the resource file
In the next step click on the MyResourceFile.resx file to display the properties. Change the "Deployment Type" attribute to "AppGlobalResource".
Now i created a asp literal control and in the text property i did the following

and then i tried to deplo the solution i get the following error

Please let me know what am i missing,actually i want to deploy my resource files under the AppGlobalResource folder.I am trying to get value from the resource file but not able to deploy my solution.
I added an empty element in my solution and then added resource file in it,after that i used to get resource file value in the mark up file like this
<asp:Literal ID="litControl" runat="server" Text="<%$ Resources:MyResourceFile, Name %>"></asp:Literal>
but when i build/deploy the solution i am getting the following error.

SharePoint DatePicker is not working in Visual webpart
Hi,
The sharepoint date picker is not working for Visual webparts created in VS 2012 (SP 2013).
In my visual webpart, I added the form digest, and then the sharePoint date control.
<script type="text/javascript" src="/_layouts/15/datepicker.js"></script>
<SharePoint:DateTimeControl ID="dtDate" runat="server" DateOnly="true" />
I get the "/ error in Application". Many websites are saying to add the below line to the datepicker:
<SharePoint:DateTimeControl ID="dtDate" runat="server"
DateOnly="true" DatePickerFrameUrl="<%
$SPUrl:~sitecollection/_layouts/15/iframe.aspx %>" />
But adding the "DatePickerFrameUrl" gives error in the "InitializeControl()" method available in OnInit().
Error: The name InitializeControl does not exist in the current context.
I have checked this:
http://developmentsimplyput.blogspot.in/2013/04/sharepoint-datetimecontrol-issue-when.html
http://sharepoint.stackexchange.com/questions/57092/sharepointdatetimecontrol-crashes-in-sp2013-webpart
but did not solve the issue. Also creating a root site for just a DatePicker control is not an option for me.
Has anybody found a solution to this?
How to use the SharePoint datepicker in visual webpart for SP 2013?
Thankshi
did you try to investigate the initial error more deeply, e.g. check stack trace in the logs? In our case it worked quite straightforward (but it was in SP2010) by adding the following control on ascx control:
<SharePoint:DateTimeControl ID="Foo" OnDateChanged="StartTimeChanged" HoursMode24="true" FirstDayOfWeek="1" AutoPostBack="true" runat="server" />
If it is problematic to check logs, you may create custom control which inherits OTB DateTimeControl, override appropriate methods in it and then check the error in debugger:
public class MyDateTimeControl : DateTimeControl

string.Empty;
// Label4.Text = string.Empty;Hi,
This is because the request is sent to the server when you refresh the page.
A workaround for this is that we can “provide a refresh link that redirects to the same page (or if you have some action causing the refresh programmatically, you could just
redirect to the page after that, with Response.Redirect)
so that page is requested by the browser (with GET method, default with hyperlinks)”.

Or we can use the Session to save a value which used as a flag for us to check whether it is a page refresh and perform accordingly.

Ensure event handlers are unhooked - Visual webpart
Hi ,
I have a visual webpart which has buttons and Images.
On click of these images and button an event handler is initiated to execute some function.
Now how and where should i dispose these event handlers.
I want the event handler to be hooked untill the user is viewing that webpart in that page.Once the user closes or moves to another page i want to unhook the event.
Where should i use the logic of unhooking event.
I have User control class which is loded in the webpart class.
Thanks in Advance.
PallaviHi,
Once a Visual Web Part is inserted into a page, we will be able to use it after the page loaded, the buttons or other controls can be clicked at that time.
When we close the page, the Visual Web Part will also be gone, the controls in it will also be inaccessible, then the functions written in the click event of these controls will
also can be executed.
If this is not you really mean, more details about your requirement would be welcome.
Best regards,

Visual studio 2012 the name "initializeControl" does not exist in the namespace in visual WebPart
Hi All,
I'm trying to create a visual webpart in SharePoint 2013 using Visual Studio 2012 and I am seeing that the file ascx.g.cs
is missing and i have this error in file ascx.cs : the name "initializeControl" does not exist in the namespace.
And like i said i use VS2012 Ultimate
Can anyone Help me please!!!
thanks.In most scenarios this is caused by some error in code preventing Visual Studio from generating the designer file. You could try to undo the latest changes and see whether the item is being generated or not. Additionally you could try checking if the custom
tool is still associated with the Visual Web Part SPI in the Properties Window.

Asynchronous visual webpart for SharePoint 2013
HI,
How to create asynchronous visual webparts in SharePoint 2013 (VS 2012) . I can see lot of examples for 2010 version, but not for SP 2013.
I have 2 visual webparts, which I want to make it as a asynchronous webpart. One webpart has the code written in Javascript client object model(loads lot of images), another is a server side webpart which has a SPGridview.
Is there any sample code available for SP 2013?
ThanksHi,
Please try to convert the SharePoint 2010 project to SharePoint 2013.
http://sadomovalex.blogspot.kr/2013/02/convert-visual-studio-sharepoint-2010.html
In SharePoint 2013, we can create a visual web part, then we can use jQuery Ajax and REST API to achieve asynchronous data loading.
