Known restrictions of animated panels?

Are there any guides to follow when using AnimatedStackPanel or AnimatedDockPanel? I tried them several times but sooner or later these panels start introducing strange UI render or user input bugs.

Examples:

  • after resizing window sometimes controls are placed out of bounds. You have to resize again 1-2pixels then suddenly everything animates into correct place (no native WinForms controls involved, everything pure WPF).
  • Sometimes the UI just doesn't update any more. It still is click sensitive, but doesn't update. Sometimes resizing the container/window helps.
  • 3rd party controls get rendered wrong: Current example (which triggered this post): RangeSlider out of "Extended WPF Toolkit™ Community Edition" 2.2.1: The left padding is always missing and the calculation of the range width gets wrong when they are near.

Hi Markus,

We aren't aware of any issues in rendering.  If you see any issues with native WPF controls, please make a new simple sample project that shows the issue and email that to our support address.  Reference this thread and rename the .zip file extension so it doesn't get spam blocked.  As for third party controls, it's hard to say what could be going on there but perhaps their measure/arrange setups aren't done properly?

Problems still present with 2016.1 on .Net 4.6.1... Seldomly just simpliest triggers on simpliest CheckBoxes don't update or even ComboBoxes don't show their context which you just selected by the use of the dropdown. If you resize the surrounding container (window/docking) by 1 pixel suddenly all bindings/triggers (or maybe just the render engine) become valid.

This seems to happen more often if animated panels are nested (this is not by direct intention but with MEF based composition sometimes huge datatemplates are combined/nested together).

If you'd like us to look into it and see if there's anything we can do, per above, please email us a simple sample project that shows it happening.  Thanks!
