Binding for "IsVisible" does not work

[Richard Koslik]

Hello!

I have a RadGridView and want to display the columns dynamically, so I use a Databinding for my variable in the ViewModel.

<telerik:RadGridView ShowColumnHeaders="False" AutoGenerateColumns="False"
                     IsBusy="{Binding bIsDataLoading}"
                     SelectedItem="{Binding SelectedDataItem,Mode=TwoWay}"
                     ItemsSource="{Binding tab_Data}" Name="grdOverview"
                     HorizontalAlignment="Left" VerticalAlignment="Top"
                     Width="640" Height="350" Margin="0,50,0,0">
   <telerik:RadGridView.Columns>
       <telerik:GridViewDataColumn IsVisible="{Binding bsColumn1}"
                DataMemberBinding="{Binding S1}" Width="{Binding iWidthsColumn1}" />
       <telerik:GridViewDataColumn IsVisible="{Binding bsColumn2}"
                DataMemberBinding="{Binding S2}" Width="{Binding iWidthsColumn2}" />
       <telerik:GridViewDataColumn IsVisible="False"
                DataMemberBinding="{Binding S3}" Width="{Binding iWidthsColumn3}" />
   </telerik:RadGridView.Columns>
</telerik:RadGridView>

In the ViewModel I initialize for example "S2=false" and call then "this.OnPropertyChanged(p => p.S2)" for my variable. After that I show the window with the GridView, but the column is still displayed! When I click onto the column the first time the data is deleted, when I click a second time the data gets visible. It looks crazy! If I set the property "IsVisible=false" without a binding the column is not shown and it works.

I have included a screenshot of my gridview.

Maybe I am missing something, so that it works.

Best regards, Richard
