I guess i was misunderstood (maybe this comes from lacks in my english).
The problem I'm talking about is the "duplication of loading panels".
Here a screenshot of my problem: http://wow.puzzle101.net/images/loadingpan.png
As told above I already made a post which includes (some aspects) of this problem.
And what Dimo told here is true on the one hand - and wrong on the other.
>>the control's Skin property value is set to "" by default, so one will not receive two animated images with the Q1 2009 version
That sounds true - but the fact is that default isn't looking that good so I have to set a Skin - which results in double animations.
The other problem - if you don't set a loading panel (keep the things as they are) - the complete controls is grayed out (especially with skin black) and somewhere is that spinner. (In the middle of the control). With big grids where you have to scroll - this is really nasty looking (the users sees only a dark gird - nothing more).
Anyhow I have to set my panel - and the result is what you see in the screenshot.
And this is not even a telerik control - it is an image - no chance to set a Skin.
I found the source of the problem - there is a skin set - I do it in web.config since my customer should be able to change the general look of the telerik controls.
But the post of Dimo brought me to a solution. I set this CSS rule:
And I have to do this for every available skin since my customer can change skins.
But finally this makes the nasty extra spinner disappear.
