Hello infragistics community -- When grouping on column 'Type', I would like to show all the types, even if no records of that type exist. If a specific type does not have a record, the GroupByRecord should read typeX (0 items).
My thoughts are that I could intercept the grouping event and see if the user is grouping on 'Type' then add a GroupBy record there somehow.
Thanks!

Thanks for the response Stefan. In the meantime, I figured the following workaround (not ideal, but it meets my requirements for now).For the types that do not exist, I add a dummy record of that type and tag it. Then, I set the Visibility of the dummy datarecords to Collapsed in the DRPloaded event. Here is some rough code for the user community:
private void DRPloaded(object sender, RoutedEventArgs e) {
// Hide dummy records. foreach (object o in (sender as DataRecordPresenter).DataPresenter.Records) { recursiveHideDummy(o); }
}
private void recursiveHideDummy(object o) { if (o is GroupByRecord) { foreach (object o1 in (o as GroupByRecord).ChildRecords) { recursiveHideDummy(o1); } } else if (o is DataRecord) { if ((o as DataRecord).DataItem is CustomType1) { if (((o as DataRecord).DataItem as CustomType1).Tag == "DUMMY") { (o as DataRecord).Visibility = Visibility.Collapsed; } } } }
