column group name issue

[Adam]

I've recently implemented the use of column group names in one of my grids and it works as it should. I have another RadGrid that's nested inside a tab control and when I attempt to add the column group names it's acting weird. I set each column to the appropriate column group name but it's setting the columns to the same group name or not setting the column group name at all..

Any thoughts?

Thanks,
Adam

Hello Adam ,

I will check this . Can you please share some details on your setup ( code/XAML) . Any info on how to reproduce the problem would be helpful.

Certainly,
Here you go. This is the tab control with two RadGrids embedded.

Hello Adam,

You should use Name property when define column group:

<telerik:GridViewColumnGroup Name="directCustomerDays" Header=""/>

Agreed,
But how is your syntax different from mine that I supplied above?

Yours:
<telerik:GridViewColumnGroup Name="directCustomerDays" Header=""/>

Mine:
 <telerik:GridViewColumnGroup x:Name="directCustomerDays" Header=""/>  

[Yordanka]

Hello,

In short, the column groups are not visual elements and the logic behind x:Name won't work in this case.

Ah, I got it.

Thanks again!
