Hi,
You can cancel the selection in the SelectedRecordsChanging event based on the TableDescriptor name.
this.gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.None;
this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.MultiExtended;
private void gridGroupingControl1_SelectedRecordsChanging(object sender, SelectedRecordsChangedEventArgs e)
{
if(e.Table.TableDescriptor.Name != "ChildTable")
{
e.Cancel = true;
}
}
Also refer this article below to know the selection types of GGC.
