Hi team,
when i try to use RadAjaxLoadingPanel inside the content page it is not display while ajax happen
but when i use it in normal page without master page then it display normally, kindly find below the details:

in the master page i have 
<telerik:RadScriptManager ID="DefaultRadScriptManager" runat="server" EnableScriptCombine="true"
        EnableEmbeddedjQuery="false">
        <Scripts>
            <asp:ScriptReference Path="~/Scripts/jquery-1.7.2.min.js" />
            <asp:ScriptReference Path="~/Scripts/jquery.corner.js" />
            <asp:ScriptReference Path="~/Scripts/jquery.blockUI.js" />
        </Scripts>
    </telerik:RadScriptManager>

and in the content page i have 

<telerik:RadAjaxLoadingPanel ID="ralpAssign" runat="server" />
    <telerik:RadAjaxManager ID="ramAssign" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="rbtnOK">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rbtnOK" UpdatePanelRenderMode="Inline" />
                    <telerik:AjaxUpdatedControl ControlID="rgAssigningDetails" LoadingPanelID="ralpAssign" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

Hello,

It seems the one property that was missing in your examples is the "Skin" property of RadAjaxLoadingPanel. To be able to show the loading image, you need to set the Skin property to any of the valid Telerik skins (like Vista, Black, Hay, Outlook, etc.).  Give this suggestion a try and let me know about the result.

Thanks Pavlina ,
I'm sorry I forgot to mention that I assign the default skin in the web.config
<appSettings>
<add key="Telerik.Skin" value="Office2010Silver"/>
however i tried to do the below
<telerik:RadAjaxLoadingPanel ID="ralpAssign" runat="server" SkinID="Office2010Silver" />
but i got the same result.
in the first postback i get the panel appear but after that no.
it is working well in IE only i don't know why.
and if i use a page without masterpage it is working well in all browsers

Hi Mohammed,

You can change your code as shown below
<telerik:RadAjaxLoadingPanel ID="ralpAssign" runat="server" Skin="Office2010Silver" />
 
and if this not helps, I will ask you to open a formal support ticket and send us a sample runnable project. Thus we will be able to replicate the described problem locally and advice you further.

Hi Pavlina,
I created a new screen and moved the other screen controls one by one and tried to test and it it is working now.
