Datagrid allow row deletion and prevent cell changes

I have been looking and can not find a good way of accomplishing this. I have a datagrid which shows information that my user has chosen. I have made it so that if the user clicks on one cell the entire row is selected. But you can still click a cell and change the contents although the entire row is selected. I want to prevent the user from being able to change individual cells, but allow for them to delete an entire row. Chester
