GGC: How to enable backspace in editable foreign key referrenced cell?

I am using grid grouping control, setting for some columns:

columnDescriptor.Appearance.AnyRecordFieldCell.DropDownStyle = GridDropDownStyle.Editable;

This columns are foreign key referrenced to other tables using ForeignKeyReference RelationKind.

The problem is that BackSpace is not working whrn editing such cell. Is there any solution to such task?

Thank you for your help.

Hi Konstantin,

You can handle the QueryCellStyleInfo event and set the Style.DropDownStyle property to GridDropDownStyle.Editable in a ForeignKeyCell. See the below code snippet for more details.

private void grid_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
if( e.Style.CellType == "ForeignKeyCell")
{
e.Style.ReadOnly = false;
e.Style.DropDownStyle = GridDropDownStyle.Editable;
}
}

Let me know if this helps.

Best Regards,
Haneef
