i use c#/wpf RadGridView. I bound i Collection calls to my RadGridView. Here i have a RadGridViewDataColumn with a cell template checkbox.
My problem ist that i have perhaps 10 items in my collection with the same telephone-no. if i check one of these items i want to check the rest of
the items in my collection with the same no. too. Also if i uncheck one, i want to uncheck the rest to. How can i do this?
