You should set DefaultCellStyle.WrapMode property of column to DataGridViewTriState.True. After that text in cells will be displayed correctly.

Set the ReadOnly property of the other columns to true. (You’ll probably need to loop through the Columns collection and use an if statement)

The ForeColor/BackColor kludge wasn’t working for me, because I had cells of different colors. So for anyone in the same spot, I found a solution more akin to actually disabling the ability. Set the SelectionChanged event to call a method that runs ClearSelection private void datagridview_SelectionChanged(object sender, EventArgs e) { this.datagridview.ClearSelection(); }
