It would be nice if you provided the same level of documentation on server side programming as you do on client side programming. Specifically I suggest you include some documentation on finding and manipulating controls on the itemdatabound event. Currently the only source for this information is in your forums and most of it consists of try this, if that doesn't work than try that. This is very frustrating because server side programming on RadGrid is substantially different than in Microsoft Grid Control.

Sample code: 

<asp:Button ID="Button1" runat="server" Text="Export" />
<telerik:RadGrid ID="RadGrid1" runat="server">
    <ExportSettings OpenInNewWindow="true" />
</telerik:RadGrid>

void RadGrid1_PdfExporting(object sender, Telerik.Web.UI.GridPdfExportingArgs e)
{
    e.RawHTML = "<a href="absolute url to pdf file">dasdasdasdas</a>";
}

protected void Button1_Click(object sender, EventArgs e)
{
    RadGrid1.MasterTableView.ExportToPdf();            
}

We are using version 2012.Q3 of Telerik, for the RadGrid control.

Once we updated to VS 2013 Update 2, we experienced a rendering problem on our development machines for all RadGrids on our site.

Upon further review we found out that this was due to the Browser Link feature in VS 2013. Browser Link appears to inject code between the development environment and the web server(s).

We were able to fix this upon finding an article pointing us towards the Browser Link feature. However it did take quite a while to figure out the issue, so we wanted to pass this along so that you could create a Knowledge Base article about this so that others can find the solution more easily and quickly.

Resolution:
Add the following item to the AppSettings section of the Web.config
<add key="vs:EnableBrowserLink" value="false" />

My Sort order of records is persisting in normal radgrid but when i am using radgrid with grouping its not persisting.

The ragGrid during page load are as folllows.

Customer group Name        Customer Name      Sort Order
Group 1
                                              Very High                    1
                                                High                          2
                                               ABC                           3

and the filer for columns format are as follow

<telerik:GridBoundColumn HeaderText="Customer Name" FilterControlAltText="Filter column1 column"
                                    DataField="Name" UniqueName="Name" FilterControlWidth="150px" AutoPostBackOnFilter="true"
                                    HtmlEncode="true" CurrentFilterFunction="Contains" ShowFilterIcon="false">
                                </telerik:GridBoundColumn>

And when i filter the grid on customer name with "high" word the grid shows results as follow

Customer group Name        Customer Name      Sort Order
Group 1
                                                  High                        2
                                              Very  High                   1
                                               
And i am needdatasource event then also this problem occurring so please provide me any solution.

I want column width state maintain on postback. here with i am attaching may aspx page

I want to use tab key for filter.
First i am entering filter text in first column then pressing tab. So i want after press tab the courser should go to next column and should allow typing. Check my demo first search with name column then press tab key the courser not going to next column and not allowing typing.

Add RadGrid Support per column/per grid for timezone like the RadScheduler 
Same with the  RadDateTimePicker, RadDatePicker and Calendar.

Hello,

When the user exports RadGrid data, an answer is sent back by the server to the client with the exported file (through response-redirect). Our project requirement is the server will create the export file, without sending such Response-Redirect.
Therefore, it would be nice to have the option to cancel the Response-Redirect.

Thanks,
Daniel.
