QuestionWPF.MDI Pin

membercolumbos1492725-Jan-13 9:37 
Hello,
I'm using WPF.MDI.dll assembly in my project.

This is my Main window XAML file:
<Window x:Class="PL.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:mdi="clr-namespace:WPF.MDI;assembly=WPF.MDI"
        Title="MainWindow" Height="400" Width="800">
    <DockPanel>
        <mdi:MdiContainer>
        </mdi:MdiContainer>
    </DockPanel>
</Window>


As soon as i added the lines:
<mdi:MdiContainer>
</mdi:MdiContainer>


I got the next message at the designer:
System.NullReferenceException
Object reference not set to an instance of an object.
   at WPF.MDI.MdiContainer.MdiContainer_Loaded(Object sender, RoutedEventArgs e)
   at System.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target, RoutedEventArgs routedEventArgs)

   at MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler)


Any body can help me solve the problem?

Thanks!!!
