GridGroupingControl: Strange behavior.

[Administrator]

Hello.

I using GridGrouingControl.
I need some workaround when new row added.
Your team provide me next code:

private void gridGroupingControl1_TableControlCurrentCellStartEditing(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCancelEventArgs e)
{
Element el = this.gridGroupingControl1.TableControl.Table.CurrentElement;
if(el != null && el is GridAddNewRecord)
{
this.gridGroupingControl1.Table.AddNew();
Record r = el as Record;
// Do something
}
}

But it occured anytime I start to edit cell from this row.
Actually I should handle only once, when start to edit new row.

Is it possible ?

Thanks. Vadim.

You can try setting a flag so your code is only hit once per new row. To reset it, you can handle the TableControlCurrentCellMoving.

private bool doOncePerNewRow = true;
private void gridGroupingControl1_TableControlCurrentCellStartEditing(object sender, GridTableControlCancelEventArgs e)
{
	Element el = e.TableControl.Table.CurrentElement;
	if(doOncePerNewRow && el != null && el is GridAddNewRecord)
	{
		doOncePerNewRow = false;
		e.TableControl.Table.AddNew();
		Record r = el as Record;
		Console.WriteLine("oncePerNewRow");
	}
}

private void gridGroupingControl1_TableControlCurrentCellMoved(object sender, GridTableControlCurrentCellMovedEventArgs e)
{
	if(e.TableControl.CurrentCell.MoveToRowIndex != e.TableControl.CurrentCell.MoveFromRowIndex)
		doOncePerNewRow = true;
}
