change headerText at runtime

[Wai]

Hello,

In the header, I would like to include the number of items in the radGrid
I have something like this after the grid is bound, but the header is not changed.

RadGrid.Columns("col").HeaderText = counter

Someone in the forum suggested to use Rebind() in PreRender event.  Does anyone know if there are any other ways to change the header?

Thanks,

Wai

Hi Wai,

Try the following code snippet to set the HeaderText of a GridColumn to the number of the items in Grid.

CS:

protected void RadGrid2_ItemDataBound(object sender, GridItemEventArgs e)
    {
        string count = RadGrid1.PageSize.ToString();
        if (e.Item is GridHeaderItem)
        {
            GridHeaderItem header = (GridHeaderItem)e.Item;
            header["columnUniqueName"].Text = count;
        }
   }

Thanks
Princy.

Thank you for your reply.

Actually, my counter is set like this:

Private Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)
    If TypeOf e.Item Is GridDataItem Then
        counter += 1
    End If
End If

I wonder if there is a way to change the header after the grid is bound.

Thanks,

Wai

Hello Wai,

This can be done intercepting the PreRender event of the grid as shown in the last paragraph of this help topic. Do not forget to rebind the grid explicitly (invoking its Rebind() method) to commit the changes.
