How do I get from Wpf DataGrid the Row, Column and Cellvalue on a click or a select event?
Is this so difficult?
I have almost the solution but not at the same time
If I put the DataGrid in SelectionUnit="Cell" I get the column and cellvalue
If I put the DataGrid in DataGridSelectionUnit.FullRow; I get the Row
But not at the same time !!!

What I have tried:
