See more: WPF DataGrid Binding

I have met following problem.
I use DataGrid and MVVM pattern. When bound collection become empty I get exception:
The specified Visual is not an ancestor of this Visual

Same problem is here:[^]

But nobody wrote about solution there...And also, I dont use grouping.
I cant find any solution in the Internet...S.O.S! Smile | :)

Thanks in advance

<DataGrid Visibility="{Binding ElementName=btnListView, Path=IsChecked, Converter={StaticResource BooleanToVisibilityConverter}}"
          ItemsSource="{Binding TitleContainsSearchResults, Mode=OneWay}"  FocusVisualStyle="{x:Null}"
          ColumnHeaderStyle="{StaticResource ResultsDataGridHeader}">

Bound property:
public ObservableCollection<CatalogueResultItemViewModel> TitleContainsSearchResults
        return titleContainsSearchResults;
        titleContainsSearchResults = value;

When DataGrid is hidden then ok, when visible - then after bound collection cleared I get excepetion
