Hi,

I'm having problems binding xamGrid with a MultiColumnComboColumn to an ObservableCollections(of Class) in my window. This is what I got:

1) An object "FSP" which is an ObservableCollection(of clsFSP), where clsFSP has the members "ID", "AR", "pf_id_01", ...
2) An Object "FL" which is an ObservableCollection(of clsF), where clsF has the members "ID", "Name", "Data", ...

I added xamGrid to my window:

<ig:XamGrid Name="xg" AutoGenerateColumns="False" ItemsSource="{Binding Path=FSP, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}">
      <ig:XamGrid.Columns>
          <ig:TextColumn Key="ID"/>
          <ig:TextColumn Key="AR" />
          <ig:TextColumn key="pf_id_01" />
      </ig:XamGrid.Columns>
</ig:XamGrid>

This works just fine, all items are displayed. Now I want to have a combolist to look up "pf_id_01" in "FL" where the member ID in clsF corresponds with "pf_id_01". So I tried

<ig:XamGrid Name="xg" AutoGenerateColumns="False" ItemsSource="{Binding Path=FSP, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}">
      <ig:XamGrid.Columns>
          <ig:TextColumn Key="ID"/>
          <ig:TextColumn Key="AR" />
          <ig:MultiColumnComboColumn Key="pf_id_01"  
                                     ItemsSource="{Binding Path=FL, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}"
                                     AutoGenerateColumns="False"
                                     DisplayMemberPath="Name"
                                     SelectedValuePath="ID">

              <ig:MultiColumnComboColumn.Columns>
                  <ig:TextComboColumn Key="Name"/>
                  <ig:TextComboColumn Key="Data"/>
              </ig:MultiColumnComboColumn.Columns>
          </ig:MultiColumnComboColumn>
      </ig:XamGrid.Columns>
 </ig:XamGrid>

This time there are displayed no items at all, xamGrid is empty. Any hint on how to solve this problem?

Thanks
