This thread is the continue problem of the thread below:
https://sharpgl.codeplex.com/discussions/441132

In XAML, there is a textbox, and has bind the TextChanged Event,

<TextBox x:Name="txtState" Width="0" Height="0" Text="{Binding StateContent, Mode=OneWay}" Grid.Row="3" TextChanged="SystemState_TextChanged"/>

But ffter display a 3D model by OpenGLControl, WPF's data/event binding lost effect.
That's to say, SystemState_TextChanged() will not be called after then on Text property changes.

And the Text is bind to View Mode's StateContent below:
   public string StateContent
    {
        get { return stateContent; }
        set
        {
            stateContent = value;
            RaisePropertyChanged("StateContent");
        }
    }
It maybe RaisePropertyChanged("StateContent"); lost effect too.

Based on several times test, On Windows 7, this problem has not occured.
