RadGrid not hiding expand column after changing of column position.

[subrat]

I have a radgrid where I hide the expand column using the code mentioned in the link below.
http://www.telerik.com/help/aspnet-ajax/grid-hide-expand-collapse-images-when-no-records-in-self-referencing-hierarchy.html

This works fine and hide the expand button correctly.
The problem arises when I move the columns.
On moving a column to a different position the grid reloads and then the Expand button appears.

Why is this happening? How can i solve the issue.
One strange thing I have observered is that on moving the columns around the page postback and the grid_PreRender event fires before the grid_NeedDataSource. I think PreRender event should fire after NeedDataSource event. Can this be the cause of this issue? How can I solve it?

Hi Subrat,

Thank you for contacting us.

A possible solution is to call Rebind() before executing the method which hides the expand/collapse images. Please check out the following code snippet.

protected void RadGrid1_PreRender(object sender, System.EventArgs e)
{
    RadGrid1.Rebind();
    RemoveExpandIconWhenNoRecords(RadGrid1.MasterTableView);
}

Another possible solution is to enable the client reordering by setting ReorderColumnsOnClient to true in the ClientSettings. This way when you reorder a column no postback will be perform.

I hope this information helps.
