Hi Yuval,
Thanks for your interest in Syncfusion Products.
This can be achieved by handling the MoveCurrentCellDirection event of the grid. In the event handler, check for e.Direction and accordingly handle it. Please try the below code.
void gridDataBoundGrid1_MoveCurrentCellDirection(object sender, GridMoveCurrentCellDirectionEventArgs e)
{
GridCurrentCell cc = this.gridDataBoundGrid1.CurrentCell;
if ((e.Direction == GridDirectionType.Left || e.Direction == GridDirectionType.Right) && cc.IsEditing)
{
e.Handled = true;
e.Result = false;
}
}
Let me know if you have any other questions.
Have a nice time.
Regards,
Rajagopal
