I have a transition control inside a viewbox.  When the transition is about to happen, the content of the transition control changes size (slight distort).

Any idea why?

Hello Jeff,

We are not aware of such problem with RadTransitionControl. Could you please give us more information about your scenario? If you send us a sample project that reproduces the problem it would be very helpful.

I am glad to assist you further.

The problem I am having has to do with the fact that I am loading an external image and there is a delay in loading.

I am still having this problem and awaiting some kind of resolution in this forum post:

Hello Jeff,

I would suggest you to load the image, before settings it to the TransitionControl. If this image comes from a RIA service, you could set the image to the RadTransitionControl when loading the data (from the service) is completed.

I hope this helps.

The problem is that I am not able to figure out a way to do that with the ContentTemplate structure of the RadTransitionControl.  If you could show an example or just write generic steps on how to accomplish this, I would greatly appreciate it!

Hello Jeff,

I would suggest you to:

1. handle the Completed event handler of the LoadOperation.  
2. In the handler, when you have the loaded image, you could set it for Content of the RadTransitionControl.

I have had similar issues with the transition.  In my example, each transition is a grid.  The contents of each grid can cause each grid to be of a different height.  For example, assume I'm transitioning from Grid_A to Grid_B.  The contents of Grid_A effectively cause the grid to be 100 pixels high.  But, the contents of Grid_B cause it to be 500 pixels high.  When the transition occurs, Grid_A is momentarily "stretched" to be 500 pixels (to match the new grid), then transitioned.  The stretching only occurs during the transition itself.  There seems to be some "matching of heights" logic going on which causes the momentary distortion.

Hello Jeff,

 As the transition is between a screenshot of the old state and the new state itself, they should be of the same size. In other case the image is either stretched or shrunk. The TransitionControl is designed to work this way.
In order to overcome this limitation you may use the FluidResizePresenter control located in the Telerik.Windows.Controls.TransitionControl namespace of the Telerik.Windows.Controls assembly - it makes a fluid change of the size which will make the transition between different sizes to look better. What you need to do is to just wrap the RadTransitionControl with it like in the following example:

If you have further questions don't hesitate to ask!

*the same resize issue is shown in any other animation(expand/collapse in treeview, menus etc) at random times.
*video is unclassified (no tags, not shared).

Hi Carlos,

Thank you for reporting this problem. This happens when there is no set size of the content. We will fix our examples in our further releases. I am glad to update your telerik points.

Hello,

I have discovered the same problem when using TransitionControl inside a viewbox. I attached xaml of the main page of a test project where this can be reproduced (there's nothing more than a Viewbox and a TransitionControl inside it bound to text property of a textbox, so when you type any text, it should draw transition effects). Note that sizes of all controls are given as fixed values, so that any autosize other than viewbox zoom is impossible. The red rectangle should remain the same, but it seems that the old view of the content template is dropped away from the viewbox and rendered in absolute measures.

Hi Mykhaylo,

 
Thank you for reporting us this problem with the TransitionControl. The issue is logged in our PITS and you can track its progress here - http://www.telerik.com/support/pits.aspx#/public/silverlight/14159. We will look into this issue in our further releases.

I am glad to update your telerik points as well.
