The header of GridViewColumnGroup doesn't gets refreshed when set programatically.

[Mausami]

Hi Telerik Team,

I have added a GridViewColumnGroup to a WPF RadGridView (version 2011.3.1220.40).

<Telerik:RadGridView.ColumnGroups>
       <Telerik:GridViewColumnGroup Name="gvGroup" Header="Header"></Telerik:GridViewColumnGroup>
</Telerik:RadGridView.ColumnGroups>

The header text is dynamic in my case. The gridview data gets refreshed on click of an hyperlinkcolumn of the same grid, so the header text of the GridViewColumnGroup also needs to refreshed. I tried changing the header text programmatically as given below.

The data in the gridview gets refreshed but the header text of the GridViewColumnGroup is not getting refreshed consistently. 
Sometimes it does gets refreshed where as sometimes it doesn't .

foreach (GridViewColumnGroup item in radgvPrerequisiteRelType.ColumnGroups)

{

           if (item.Name == "gvGroup")

            {

               item.Header = null;

               item.Header = "ProjectId [" + lngProjectId + "]";

            }

}

Could you please let me know the solution for this problem.



Thanks,
Regards,
Mausami

I have the same problem. Is there a solution to this problem, Telerik?

Hi,

I would recommend the standard approach of binding rather than setting things programmatically in WPF.

You may expose a small view model as a static resource on the window / user control. The view model will contain the values that would change over time. You can then bind the text of a textblock in the header to a value of this view model.
