    We just bought the full telerik suite. We had been using the Q2 trial and now are upgraded to Q3 developer. After doing so, we now have weird issues.

    I have a page with some controls in this hierarchy
    - RadSplitter
    --RadSlidingPane
    ---RadAjaxPanel
    ----various regular controls like RadioButtonList, ListBox, etc

    So after my AJAXPanel comes back from a request, my controls are visible for 1 second, then they disappear.

    This started happening after I upgraded. This does not happen in Safari or Firefox.
    It happens in IE7 and 6

    Help please.

    Hi Matt,

    The observed issue is a problem in the Q3 2008 release, but is fixed in Q3 2008 SP1. Are you using the latest version of RadControls for ASP.NET AJAX?

    More information is available here:

    Your solution does not work. I don't use the VisibleDuringInit property but I tried the fix anyway and i get the same result.

    If I take my controls out of the ajaxPanel and run, I don't have a problem. I really need to not have to PostBack the whole page though.

    I don't know if you got the problem solved Matt, but I had a similar problem before, with the exact same behavior.

    The problem of controls appearing and then disappearing in IE is CSS-related.

    Check to see if you have a DIV tag around them with the following CSS property: position:relative

    If so, what might be happening is everything loads correctly and then disappears when the CSS is applied, in which case you can try placing placing your rotators inside a non positioned DIV.

    Hope this helps...

    Hi there,

    I have the same problem as Matt and Ricardo. My controls disappears when they are inside a DIV tag with the following CSS property: position:relative. The problem is that I need to keep this property, I can,t just delete it ... or disable my RadAjaxPanel AJAX property.

    Is there any other solution ?
