In the following example SelectedValue of TabControl is always null.

I have a DataTemplate I want to reuse. The part I want to factor out is the binding, because it's the only thing that changes. My DataTemplate looks roughly like this. (There's actually quite a bit more to it, but I've taken out the extraneous stuff.) <DataTemplate> <TextBox Text="{Binding Name}" /> </DataTemplate> How can I reuse...
The following code puts the two text elements at the top even though the second one is marked "Bottom". The background color goes all the way to the bottom so the DockPanel seems to stretch to the bottom.

I have a slider with minimum value 0 and maximum value 1. When I currently slide it, the value gets set to a decimal value between 0 and 1, e.g. 0.2342343. However, I want the value to only be either 0 or 1 (so that my ViewModel property will register the change only if it is 0 or 1 and not multiple times as the user drags it from 0 to...
In the following code example, you can move the slider from German to English and see that text block get translated at runtime, however: only the TextBlock bound to a string gets updated the TextBlock bound to a Dictionary does not get updated It seems that the View simply gets the Dictionary object once and then doesn't update anym...

Over at the StackOverflow question How can WPF Converters be used in an MVVM pattern? I've learned that Value Converters should not be used in the MVVM pattern since the functionality of a Value Converter should be handled by the ViewModel itself. This makes sense. But I remember reading that you should not expose XAML elements to the ...
Is it possible to use a multiTrigger to evaluate properties on multiple elements? That don't reside within a template, but are within the Usercontrol/Window. Example: <CheckBox x:Name="checkBox1" /> <CheckBox x:Name="checkBox2" /> <CustomControl> <CustomControl.ContentTemplate> <DataTemplate> ...

Why do we have to spend more $$$ for Expression Blend after I already spent $$$$ for Visual Studio 2008 with MSDN subscription? Will there be a service pack for 2008 to support this, will it be part of VS2010, or will we always have to use a separate tool? Thanks ...
I have a couple of applications for clients that were dragged into the web kicking and screaming. I'd like to take a crack at moving some to Silverlight 3.0 if even just as a proof of concept exercise. I'd like to see if I could make them full apps, layout and all. I think the layout of the web app along w/ the graphics is good and do...
In the following code, I tell the ComboBox to use the DataTemplate called CustomerTemplate by assigning its ItemTemplate attribute. StackPanel, however, doesn't have an ItemTemplate attribute.

I could put a fixed Width in the Border element, but then a very long customer name might get cut off.
