View 3 RepliesI have a custom datagridview control. I am loading data into it row by row. The control does not resize its cell width to its content. It only does so if I set autosize column property to Fill or AllCells. The problem is I can not use autosize because its killing my performance as I am loading large amount of data into the grid.
The cell does not display the contents completely, it just clips it. e.g for "sampletext" it would display "Samplet..." .
I want the cell to be resized according to the cell that contains the longest string value.
