The following code makes the contents of a StackPanel fade in when it is loaded (StackPanel.Loaded). What do I have to change to get the fade it to start when the contents of the StackPanel change, e.g. every time a message in the StackPanel changes I want it to fade in again? <Style x:Key="MessageStyle" TargetType="StackPanel"> <S...
When using fx. Word, I'm able to specify how much the font spacing should be reduced in points (ie. Condensed 3 pt). In XAML I can only use values from the FontStrech enum. Is there any other way specify the condensing in XAML, or is the only alternative to use a transformation to achieve something similar? ...
Ordinarily I wouldn't just post an error message on SO, but after a Google search only found one hit, I thought I'd at least open the floor for this error here on SO.

I found on Window object StateChanged, but it fires when Window object is already in Minimize state, then it's too late. So, I need something like "StateChanging" event to handle, while Window object is still in previous state. Is it possible t...

Hi, I'm certain this has come up before, but I haven't been able to find the answer.

I also have a ListBox and a TreeView that are databound t...

So I have a StackPanel that I am using as a ContentControl. I have a place where I want buttons to be generated based on data that I am binding to, and that is all working good, but I want the buttons to be laid out horizontally, not vertically as is what is currently happening.

Hi, What's a good method to bind Commands to Events? In my WPF app, there are events that I'd like to capture and process by my ViewModel but I'm not sure how. Things like losing focus, mouseover, mousemove, etc. Since I'm trying to adhere to the MVVM pattern, I'm wondering if there's a pure XAML solution. Thanks! ...
Hi, I am binding a list of items to a ListBox, I need some help with XAML to be able to display a button for each item.

I also need to stop the row highlighting for the ListBox, as the button ...

Hola, I'm developing a Silverlight app and would like to create a grouping of 5 toggle buttons (used for menu options) that animate when clicked (grow in size) and also cause any previously clicked buttons in the group to unclick and animate back to their shrunken size. I know I could use a brute force approach where the app is directl...

With WPF 3D, is it possible to have a texture with an alpha channel? I am wanting to make a 3d scene where everything is flat surfaces (like everything is paper cutouts).
