code-behind

In an asp.net windows forms application, in the C# code behind you can use: MessageBox.Show("Here is my message"); Is there any equivalent in a asp.net web application?

There are several examples of how to populate a tree view from a collection of file paths such as this or this other example. I cannot seem to find such example for WPF. I know I can integrate windows forms and use a different control in order to make it work but it will be nice if I could do the same thing with a wpf treeview control. The tree view that I want to construct consists of about 50,000 files therefore I think it will be better if it is bind it to something.

I'm trying to access a user control which is inside the control template of a content control. Specifically: <ContentControl x:Name="MyList" > <ContentControl.Template> <ControlTemplate x:Name="MyControlTemplate"> <Border RenderTransformOrigin="0,0" x:Name="border"> <UserControls:MyControl x:Name="MyControlName" Width="100" ViewModel="{Binding}" /> I can access this.MyList but it says this.MyControlName is not found.
