Hi Al,
You would have to override the ListBoxMouseUp method in a MyComboBoxCellRenderer class and set the selected value of the ListBox to cell using the below code.
protected override void ListBoxMouseUp(object sender, MouseEventArgs e)
{
MyObject curobj = new MyObject();
if( ListBoxPart.SelectedItem != null )
curobj.Value = ListBoxPart.SelectedItem.ToString() ;
Grid.Model[RowIndex, ColIndex].CellValue = curobj;
base.ListBoxMouseUp(sender, e);
}
Please refer to modified sample for more details.
