I'm having an issue when triggering a storyboard from the code behind. I've just changed the storyboard to use a dependency property, which works, but only after the calling FindResource() twice. I build the dependency property using a UIPropertyMetadata object to set the initial value which appears to work. Does anyone know what I'm doi...

I found and inserted the code below on my navigation-based WPF application~ It worked on my (development) machine no problem but when I released it on the workstations, it was quite slow. I noticed that when the application is not maximized, it works at normal speed, but when the app is maximized, it looked like the application stops for...
Why do animation classes (like DoubleAnimation) require dependency properties? Dependency properties have a lot of overhead when compared to a simple property. Wouldn't passing in an object and property name and using to reflection to retrieve a setter delegate have made the animation classes more flexible and generally more usable? I...

I've been trying to animate around 1000 lines which are all added to a Canvas, and it is extremely slow to the extend that animation is not feasible at all. At first I thought it was probably because of all the calculations, but then I tried a very simple experiment. I generated around 1000 random lines and I tried to move them to new r...
I am poking around the animation in WPF and I am confused. For RectAnimation, By cannot be negative for height and width. So, if you use the "By" keyword, rectangles can only grow (instead of "To")? Here is some example code: <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsof...
This is a two part question from a WPF animation newbie. First, here is my code: public void AnimatePaneBox(ContentControl destination, UIElementCollection source) { // Create a NameScope for this page so that // Storyboards can be used. NameScope.SetNameScope(this, new NameScope()); Canvas ...
I have an animation that I have setup on a transparent canvas. I set that canvas to be the content of a button and then run the animation. (See this question for the code.) The problem is that sometimes the animation gets put behind other UI elements of my app (I am using Avalon Dock and it is in front of the DockableContent it is in,...
Hello, What is the best way to trigger an animation while using the MVVM pattern? More specifically, I have a form which has several fields. When a user click's the save button, I would like to show an animation. I have been able to achieve this by exposing a property ShowMessage and setting it to True and a DataTrigger picks up this va...
(Note: I have seen this question and it uses a cursor not an animation.) I have a wait animation (that I did not make but found on the internet). I want to show it while my app is doing some processing. However, it gets stuck while my app is processing. Is there a way to make it keep going smooth? I usually think of a thread for t...
Hi, In WPF, when a user gets focus in a TextBox, I would like some animation that would make the TextBox becomes multiline and make its width bigger (while he is typing) and when the focus is lost, that the textbox goes back to its original size. The size is unknown. Also, ultimately, that TextBox needs to be within a WPF Datagrid. I...

Hi, I have to change the color of a TextBlock to indicate whether the number is positive or negative - red for negative, blue for positive.
