I just spent some time at Bart de Smet's online blog and found it to be not only useful information for developers but at the same time interesting, fun, reading. The author obviously not only knows his subject matter, but has a talent for making his writing enjoyable to read: ...80 centimeters behind me lies the answer in dead tre...
After you have added Items to the "root" level of a System.Windows.Controls.TreeView, what is the proper way to add in "subitems" by name? System.Windows.Controls.TreeView.Items <-- doesn't seem to have a Find() or [] by name. UPDATE: Oh, wait... is it TreeView.FindName() ? Actually looks like FindName won't work because it returns ...

I have an object that can't inherit DependencyObject OR use NotifyPropertyChanged, and I've binded it to quite a few controls, so when the properties change, I don't want to go to each control and change it's value on the code, so I'm thinking there must be a way to tell the XAML to "Rebind" all that it's bound to with one or two lines o...

Hi, I'm just starting to use the composite application libraries for WPF. In my shell I have a region in a tabcontrol that is used to display different types of views. I also have a toolbar with buttons hooked up to commands, for example save. The commands are bound in my views, and the views have the canExecute and execute methods. T...
Has anyone been able to solve the airspace issues when trying to play a flash (swf) movie in a WPF application? I've been able to play the swf file using a WinForms control and a WindowsFormsHost element, and also using the WebBrowser element - but both have the airspace issues. ...
In my ViewModel I have two commands: ICommand ExecuteMeOnCheck { get; } ICommand ExecuteMeOnUncheck { get; } I wish to attach these commands to a CheckBox and have one of them execute when it is checked and the other execute when it is unchecked.

I'm trying to force a grid/expander to reevaluate whether it needs a scrollbar, as it's showing emptiness. I'm using this layout: <Grid> <toolstrip /> <!-- fixed height row --> <Scrollviewer> <!-- * height --> <Grid> <!-- all rows are 'Auto' height --> <Expander /> <Expander> <!-- this one stretches far too high --...
I need an Image that is grayed out when disabled (IsEnabled=False). A grayed out version of the image can be produced by reading the BitmapImage into a FormatConvertedBitmap which is shown here. I have been able to get this working with a UserControl but now I would like the same behavior in a specialized Image class for more flexibilit...

Would it be worthwhile to convert the application into Silverlight 3 so that they would be able to run/install it on OS X? Will the full features of Silverlight 3 be supported on OS X (like the install feature), li...
I can't figure out what I'm missing here. Here's the problem: Consider a (Control|Data)Template with a Trigger that switches visibility of some inner UI elements. E.g. show a TextBlock when IsReadOnly==true and show a TextBox when IsReadOnly==false. Everything is perfect if you do this without animation - one or two setters would do th...
