I have been trying to implement drag and drop within a listbox in my application and I can’t seem to get the following lines to work from the tutorial and other solutions that admins have posted on the forum:
<vsm:VisualState x:Name="NoDrop" />
I get the following error message from VS:
The tag 'VisualStateGroup' does not exist in XML namespace 'clr-namespace:System.Windows;assembly=System.Windows'.
Is there something I am missing?
I am using VS2008 in Windows XP and the trial version of Telerik RadControls for WPF.
Any help would be greatly appreciated! :)
