Unable to group gridview

[Joseph]

Hi,
I'm new to Telerik and have just downloaded the latest WPF trial.
I'm having trouble with the Gridview (version 2010.3.1110.35).
I'll post the XAML below, but I'm populating from an observableCollection pulled from a WCF service.
The grid populates OK, but I cannot group the columns please can you advise.
The window is binding to an ViewModel.

I've tried another sample wher I create some objects on the fly, putting them into an observableCollection and binding to it ... and
the grouping has worked fine.

Many thanks,
Joseph.

Hi,

Think I've found the culprit.
I was doing this in the Window_Loaded method...

StyleManager.SetTheme(radGridView1, new Office_BlueTheme()); 

Moving that into the constructor seemed to make the problem go away.

Please could someone confirm this as a problem... Or, was I wrong putting that line of code in the
Window_Loaded method?

Thanks,
Joseph.

Hello Joseph,


Window's Loaded event is to late to set a theme, it is working in InitializeComponent because that is the right place.
