I used a sample project from another post and have a RadGridView as the DropDownContent for a DropDownButton. The Content of the Button is bound to the SeletedItem of the GridView. And I created a ContentTemplate to display a piece of data from the SelectedItem.
How do I display something (a message that says "Select Source" or something similar) when no item is selected in the GridView. Would I use a TemplateSelector? If so, How? I'm not sure and I've never used TemplateSelector.
Here is my scaled down code for my ddb:
Thanks.
