See this thread for a similar issue, there is a workaround posted but in your case binding the ToggleButton's Enabled property to AllowChange might be better.

Aside from warning you about using globals AND public members, you can't use an instance. Try this syntax: Globals.GlobalInts["two"]; If you remove the static modifier, you'll be able to use the instance reference.

Ron, Yes. Give this article a look: http://www.codeproject.com/KB/WPF/WPFTaskDialogVistaAndXP.aspx[^] This is where you need to make a decision. You can have all custom dialogs or use the operating system ones. For the message boxes, I wanted my XP users to have the rich features of the TaskDialog so I wrote the above library to provide that. I also have similar boxes for my file dialogs.

My Bad. I should have noticed this. Good job! 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.

Ok. This works. <Window x:Class="ZoomTest.Window3" x:Name="Me" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window3" Height="300" Width="300"> <StackPanel> <ProgressBar x:Name="Progress" Value="{Binding Path=Val, ElementName=Me, Mode=Default}"/> <Slider x:Name="MySlider" Value="{Binding Path=Val, ElementName=Me, Mode=Default}" Minimum="{Binding Path=Minimum, ElementName=Progress, Mode=Default}" Maximum="{Binding Path=Maximum, ElementName=Progress, Mode=Default}"/> </StackPanel> </Window> But I hate Me. It reminds me of VB. Ideally this would be more concise but doesn't work: <Window x:Class="ZoomTest.Window3" x:Name="Me" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window3" Height="300" Width="300"> <StackPanel> <ProgressBar x:Name="Progress" Value="{Binding Path=Val}"/> <Slider x:Name="MySlider" Value="{Binding Path=Val}" Minimum="{Binding Path=Minimum, ElementName=Progress}" Maximum="{Binding Path=Maximum, ElementName=Progress}"/> </StackPanel> </Window> Is there any way to set the default data context to the window for all of it's children? Sincerely, -Ron

Yes that worked. Thanks. :) Sincerely, -Ron

That's a nice little control you've put together there Dave. 5. Deja View - the feeling that you've seen this post before. My blog | My articles

Thanks Mike. Can't believe I didn't see it.:-O Sincerely, -Ron

Did you read the docs for TabControl? There's a TabPages collection property that has a collection of TabPage instances. Sub-class the TabPage if you want, but you don't need to. The TabControl is fully designable in VS.NET as well. Just try it out. Microsoft MVP, Visual C# My Articles
