In a previous article I described how to build a Blend 3.0 Behaviour that logged details based on an event on a UIElement. This article moves a little further forward in that a TextBox element is enhanced to provide a watermark when the text is empty.

With this behavior, we would be able to set focus to any controls when we trigger any control events.
For example,wheneverwe click the button, we want to textbox got focused, or when we select the Option 1 for the veryfirst time, the textbox will get focused as below image.

A collection of useful triggers and actions: MouseWheel support for ScrollViewer using smooth animations, HideOnInstall behavior, InstallAction, ToggleFullScreenAction, ToggleVisibilityAction.

Collection of triggers, actions and behaviors that I've been using for various prototyping and experimentation. This includes the full list of behaviors that I demoed at MIX '09, plus some more experiemental ones.
