I have a WPF program to which I need to add a "Demo mode". Since I want my designers to be able to modify the demo mode without me having to recompile the program each time, I tough it would be a great idea to use a storyboard from an external XAML file. The "Demo mode" is basically a storyboard animating some of the application's depend...

Hi there, I'm struggling with a binding that only works when declared inside a Window's resources area. As soon as I move the declaration to a UserControl's resources area, the binding fails. No error message, but the value is not updated when the value of the slider (source) is changed. I would like to use the storyboard inside one of ...
I've been teaching myself WPF through Sells/Griffiths' "Programming WPF", and I've found it a great resource, but I'm trying to take some of the concepts they've introduced me to and go a step further, and I'm running into a conceptual snag on how to put the pieces together to accomplish what I'm trying to do. In this exercise, I'm tryi...
I have multiple storyboards that access the same property (not at the same time). After one storyboard changed the property, the other one seems to have no access to it and does not change anything.. What can I do against this? Sample: <ListBox> <ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Sett...

I'm trying ... myStory.Stop(this); Expecting that a subsequent call to .Begin(this); would restart from the timeline at zero, but instead, the storyboard picks up right where it was stopped. I have tried .Remove(this); and I tried .Seek(TimeSpan.Zero); w...

I am animating the user control's opacity, scaletransform.scalex and scaletransform.scaley to pop it in and out of view. It looks cool except for the first time it runs. The animation is set to take 3/1...
I have a trigger on a storyboard for my listboxitem where the trigger is 'Loaded'. It appears that every time the listbox scrolls the item gets the 'Loaded' event. I really only want the storyboard to run once, when the listboxitem gets displayed. I assumed that the Loaded event would only get triggered once. Any help would be great. ...
In an XAML document, I have a gradient brush as a resource and a bunch of shapes that use this resource. I would like to animate the brush using a storyboard, but I don't know how to set the brush in resources as the target of storyboard.

This is a situation that comes up often: In the View, you have a control bound to a ViewModel property (backed by a INotifyPropertyChanged). For example: <TextBlock Text="{Binding Path=Subtotal}"/> When the property changes, you need to bring the user attention to the fact with some creative animation. How I can utilize the fact that...
