Hi,
I've a XamDataGrid with a bound DataContext (A List).
I want to make (For now, the count property of the list) the UnboundField showing this property.
So, I've created this binding:
Binding Path=DataContext.Count,RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type igWPF:XamDataGrid}}}
Unfortunately, I got this binding error: System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Infragistics.Windows.DataPresenter.XamDataGrid', AncestorLevel='1''. BindingExpression:Path=DataContext.Count; DataItem=null; target element is 'ValueHolderWithDataContext' (HashCode=62236609); target property is 'Value' (type 'Object')
Did I miss something? I think, It must be possible to bind an UnboundField out of the field scope...
Thank you,
this is exactly what I want to know!
Hi
Can you try this binding:
<igDP:UnboundField Label="Count" Binding="{Binding Path=Cell.DataPresenter.DataContext.Count, RelativeSource={RelativeSource Self}}"/>
And let me know if that is what you were looking for?

in this case every cell have the same value.because every cell is bound to the list's count property.
But this would be something I could build on...
I am sorry but I am not sure I follow the scenario. Can you provide more information or a sample application ?
The XDG unbound field is bound to a list of objects that have count property ? Or the idea is to bind the unbound field to the list's count property because in that case all the cells will have the same value ?
Thanks,
Slavi
