Ok now i see what you mean I've set my project to work with Luna (XP) only (in the App Resource) Unfortunatley, it doesn't solve the problem...

You can find something like that in the downloadable code examples for the Apress book PRO WPF by Matthew MacDonald(Chapter 24) but it doesn't support the paste/copy functionallity. I hope this helps Uros Bregar

If I wanna design an application , I'll use XAML code.

Thanks, I will appreciate if anyone have an idea :) it's a tricky one

Thanks a lot, it's a great solution

Can you post an example? My control doesn't have the event, the scroll viewer does. and it's not necessary exist

It's a 3rd party product which i have the code for

Thanks for the help. unfortunatley i think it won't work for me. The data binding thing i can do only if i know in advanced which items will be in the combo box. what if i bind it to a list of strings? about the automatic thing. it didn't work. i have enough room in a grid's auto size column. the combo box just change it's width every time i choose something from the list to fit the minimum width required (by controls on the same column) any solution for that? Thanks, Yanai

Thanks, Isn't there any source for common practices? GUI has evolved a lot in the past 10 years and i would really think there will be a source for dos and don'ts, ground rules or something like that

Yanai, Just handle the PreviewMouseLeftButtonDown event for the TabControl. Then check if the Source of the RoutedEvent is a TabItem. Perform your testing to see if you want to cancel the event and if so use, e.Handled = True to handle the event which will cancel the tab page switching. Private Sub tcPages_PreviewMouseLeftButtonDown(ByVal sender As Object, _ ByVal e As System.Windows.Input.MouseButtonEventArgs) _ Handles tcPages.PreviewMouseLeftButtonDown If TypeOf e.Source Is TabItem Then 'perform your test here 'if you want to keep editing then use this code e.Handled = True End If End Sub Cheers, Karl » CodeProject 2008 MVP » Microsoft MVP - Client App Dev My Blog | Mole's Home Page | MVP Profile Just a grain of sand on the worlds beaches.

Sounds like ShowMeTheTemplate which uses the WindowsFormsHost and WebBrowser control, there is a better WebBrowser control in .Net 3.5 Sp1 beta. The RichTextBox would support the indentation but you would have to do the syntax highlighting yourself if you wanted that.

but in SelectionChanged you can't cancel the selection, only add stuff to when it's happening

If it wasn't too complicated then I'd look at extending the ListView - the beauty of templates is that you can turn something like the listview into a grid control without too much effort. Mind you, I do use Xceed WPF Grid as well - it's very nice (and free too in the basic version, always a plus point with me). Deja View - the feeling that you've seen this post before.
