GridGroupingControl: How to implement Cancel.

[Administrator]

Hello.

Please tell me, how to leave the form with control, if the input is not complete (or not correct).

I try .CancelEdit() in Cancel button handler, but control cannot leave focus, cause cannot validate input.

So, how to implement Cancel.
Thank you. Vadim.

One way you can do this is to handle the TableControlCurrentCellValidating event, and if you are clicking on your cancelButton, call CancelEdit on the CurrentRecordManager.

private void gridGroupingControl1_TableControlCurrentCellValidating(object sender, GridTableControlCancelEventArgs e)
{
	if(this.cancelButton.Bounds.Contains(this.PointToClient(Control.MousePosition))
		&& Control.MouseButtons == MouseButtons.Left)
	{
		if (this.gridGroupingControl1.Table.CurrentRecordManager.IsEditing)
		{
			this.gridGroupingControl1.Table.CurrentRecordManager.CancelEdit();
		}
	}
}
