Hi, is there any way to determine the visible region of a WPF control that is clipped by parent controls (e.g. ScrollViewer, Canvas, or panes)? Background of my question: we are using the WebBrowser control in our application. Since it is derived from HwndHost, parent controls cannot clip it, i.e. it will overlap parent controls, whic...

I have a strange behavior in VS2008 a few times: After some changes in a xaml file, removing a control with a compile time error, VS2008 keeps saying the error is still there, even when the control itself is not there anymore. I could only fix it by creating a new xaml file, copying the content and deleting the original file. I cleaned t...

I...

I am developing a WPF app that contains a webbrowser control that loads a silverlight application. I would like to be able to launch the app from visual studio (F5) and have the debugger attach to the silverlight code. However, I've not had any luck with this.

I have a ContentControl bound to a PhoneNumber object, and the control's Style.Triggers applies different ContentTemplates when the control has or doesn't have keyboard focus. <Setter Property="ContentTemplate" Value="{StaticResource DisplayPhoneNumberDataTemplate}" /> <Style.Triggers> <Trigger Property="IsKeyboardFocusW...

Hello, It appears that the args object passed into an override of OnPreviewMouseLeftButtonDown describes the current (live) mouse button state, not a snapshot of the state present when the event occurred. Is this proper behavior? Shouldn't event arguments reflect event data at the moment the event occurred (a snapshot) and not be autom...

This is how I'm doing it now in my data class: MainWindow.Instance.Menu1Instance.Button1.Click += new RoutedEventHandler(Button1_Click); Proble...

The binding is partially there because the view model's property getter and setter each get called once when a row is selected (And thus causes the details view to expand). However t...
