I use a trigger like this to set a brush for my selected row:
It kind of works, my row is still "standard blue" when selected and the selected cell have a black border. BUT If I scroll the grid horizontal I see my selectionbrush on barts of the row where there is no cells...
How shall I do? I want the hole selected row with my own Brush, and no borders on the selected cell. I have SelectionMode="Single", and GridLinesVisibility="Horizontal"
