I have DataGrid, I setup its ReadOnly property to true. But I still can click on the individual cells and they get highlighted. Is there way to allow to select only the whole row? I need it because I have the contects menu for the DataGrid, but if I select the cell(if I click on the cell) and then click the right button on the mouse, some system contects menu pops up with "Cut, Paste ect." instead of my contects menu. Can somebody help me?
