i have a TabControl with a DataTemplate including a Radgridview and a Toolbar.
When a row in the Grid is selected I want to enable a Button in the Toolbar.
My Question is: How can I access the properties of the button in the same TabItem?
I have tried the ParentOfType property for the Sender Object in the "SelectionChanged" Event of the Gridview, with no success.
How can I achieve this?
