Hi Dinesh,
Thanks for your patience.
You could try the code below in the TableControlCurrentCellKeyDown event of the grid, to detect the changes made to the checkbox cells through spacebar.
void gridGroupingControl1_TableControlCurrentCellKeyDown(object sender, GridTableControlKeyEventArgs e)
{
GridCurrentCell cc = e.TableControl.CurrentCell;
if(e.Inner.KeyCode == Keys.Space && cc.Renderer.StyleInfo.CellType == "CheckBox")
Console.WriteLine("CheckBox state changed");
}
Let us know if you have any further questions.
Have a nice time.
Regards,
Rajagopal
