After first Window open/close, window opens invisibly

[Gary Davis]

This code used to work but now does not (WP7 nor WP8). Clicking a button opens the RadWindow and clicking a button within the window or outside the window closes the window. The first time, it works correctly and from then on, does not.

The 2nd attempt to open the window does work (opening and opened events fire) but the window does not display. Closing the invisible window does briefly pop up the window and the close animation runs.

The open animation is set to use the default properties which assumes Axes="Y". If I change to use Axes="N", the open animation works and the invisible window is left displayed. So this is a good temp fix but I'd like to use Axes="Y" on the open.

I have a test project but was unable to attach it to this post.

Hello Gary,

Thanks for writing.
I am not sure why this XAML has worked previously. Your animations should have FillBehavior="Stop" set on them in order for the end values of the animation to be removed after the animation has finished. If you have a look at the default window animations they have FillBehavior="Stop" set for the same reason.

All the best,

Thanks, that did work.

I don't know why it used to work - I have at least three apps in the store from about a year ago with that code and they do work with the Axes="Y" and no FillBehavior="Stop".

Thanks.

Hello Arun,

Did you set the FillBehavior to Stop as mentioned on this thread?
