RadGrid - SharePoint Postback Events Issues

[Michael]

I'm currently using the Telerik Controls for Ajax with SharePoint 2010 to create custom web parts and I'm having an issue with the RadGrid and posting back events.

I am dynamically creating the grid in the CreateChildControls method of the SharePoint Web Part and binding the grid on specific conditions.

Allow Sorting is true:

this.gvDocumentsGrid.AllowSorting = true;

With this event:

this.gvDocumentsGrid.SortCommand += new GridSortCommandEventHandler(gvDocumentsGrid_SortCommand);

I've also tried using the "NeedDataSource" event, but whenever I click on a column header to sort the grid the page does postback but the SortCommand event is never fired and I lose the binding. I also have the RadAjaxManager registered in my masterpage.

What am I do doing wrong? This is extremely frustrating.

Hi Michael,

I suspect the problem is due to incorrect ajax settings. You need to add those on the OnLoad event of the web part:

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);

    AddAjaxSettings();//custom method where your ajax settings should be created.
}

In addition, do make sure to call the EnsureChildControls() method in the OnInit event:

protected override void OnInit(EventArgs e)
{
    base.OnInit(e);

    EnsureChildControls();
}

If the problem persists, try pasting your complete code-behind using the CODE-FORMATTER tool of the ticket editor.
