    Hi there,

    it's working fine on IE7, Firefox, Chrome.

    On IE8 it just has full background color. Is there any workaround for this?

    I have tried both setting transparency for the radajaxloadingpanel declaratively + through CSS opacity property.

    Hello waircit,

    Please try our online demos:


    If the problem exists there as well, then check your browser security settings - probably they are too restrictive with regard to scripting, ActiveX, etc.

    Best wishes,

    The demo does not answer the question (which I have as well).

    In the demo, the declaration does not include transparency, e.g. 
    <telerik:RadAjaxLoadingPanel ID="LoadingPanel" runat="server" Transparency="10"

    In IE8, the circle that shows progress, does not show. In all other browsers it does.
    Any solution (other than ignoring the Transparency capability?)

    Hello Chen,

    Internet Explorer does not support animated images placed inside an element with a filter style applied (the transparency in IE uses such a style).

    You can workaround this by creating a custom skin for RadAjaxLoadingPanel and use the desired loading image there.


    Also you can simply override the styles of an existing skin, you need only these three CSS rules:
    .RadAjax_[Skin_Name] .raDiv /*use this rule if you need to change the loading image */
    .RadAjax_[Skin_Name] .raColor /*use this rule if you need to change the bg color*/
    .RadAjax_[Skin_Name] .raTransp /*finally use this rule for changing transparency level*/
        -moz-opacity:0.2; /*For old Mozilla Browsers*/
        filter:alpha(opacity=20); /*For IE*/

    I hope this helps.

    Setting transparency=0 solved IE8 image display problems, thank you! (2012 Q1)
