    I have a quick question.

    Is ther any way to use the Ajax Loading Panel for all Controls on my site that doing a Postback?
    I don't want to define all controls in the manager that do a postback.

    I just want the ajax loading panel to show up every postback.

    Is this possibile?

    Thank you for reading.

    Hello Daniel,

    You could simply wrap the whole page with RadAjaxPanel control and set DefaultLoadingPanelID for it in order to have Loading Image to appear for each request.

    Hi Maria,

    thank you. I tried it, but if the site postback its nothing happened:/

    I added a screenshot how i define RadAjaxPanel and LoadingPanel.

    Is it correct like this?

    If yes, why the loading panel didn't popup?

    Thank you, Daniel.

    Hi Daniel,

    Please try the following sample code snippet which works fine at my end.

    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">
        <asp:Label ID="Label1" runat="server" Text="Loading..">
        <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/round-loading-icon.gif" />
    <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" LoadingPanelID="RadAjaxLoadingPanel1">
        <asp:Panel ID="Panel1" runat="server">
            <asp:Label ID="Label2" runat="server" Text="Demo">
            <asp:Button ID="Button1" runat="server" Text="Load" OnClick="Button1_Click" />

    protected void Button1_Click(object sender, EventArgs e)
