See more: WPF DataGrid Binding
Hi

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: http://wpf.codeplex.com/workitem/9699[^]

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

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

Bound property:
public ObservableCollection<CatalogueResultItemViewModel> TitleContainsSearchResults
{
    get
    {
        return titleContainsSearchResults;
    }
    set
    {
        titleContainsSearchResults = value;
        OnPropertyChanged("TitleContainsSearchResults");
    }
}

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