RadComboBox and CallMethodAction

[Poubelle]

Hi,

I’m developing a Gridview application in Silverlight, where i’ve got inside a CellEditTemplate with a RadComboBox. I need to call specific method in my ViewModel when i click in my RadComboBox. How can i redefine again my context to fin the method, because with my code (below), I’ve the error that say my RadGridView ItemSource do not contains my method.
Anyone can help me?
Thanks
Regards

Hi,

I’ve found a solution.
1) Add my ViewModel as ressouce in my window

<Window.Resources>
   <AppViewModel:MainWindowsViewModel x:Key="MyViewModel"/>
</Window.Resources>

2) Change the DataContext from the RadComboBox

DataContext="{Binding source={StaticResource MyViewModel}}"

Thanks all.
