Loading panel does not work in a RadGrid inside a RadDock

[JR]

Hi,

I'm using a RadAjaxManager to handle postbacks for a RadGrid insde a RadDock.  I specified a default loading panel but it doesn't seem to work.  Loading panel does not display.  

The RadDock contains a search function that will bind the results to the RadGrid.

Sample code:

    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"
        DefaultLoadingPanelID="RadAjaxLoadingPanel1">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="rtbSearch">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="rgDefinitionList" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
    </telerik:RadAjaxManager>
    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default">
    </telerik:RadAjaxLoadingPanel>
    <telerik:RadDockLayout ID="RadDockLayout1" runat="server">
<telerik:RadDockZone ID="RadDockZone1" runat="server" Orientation="Vertical" Style="border: 0px; float: left; margin-right: 1px; margin-bottom:1px; width:100%;">
        <telerik:RadDock ID="rdSearch" runat="server" Width="300px" DockMode="Docked" Title="Fee Definitions" DefaultCommands="ExpandCollapse" EnableAnimation="true" EnableEmbeddedSkins="false" Skin="LWTSkin">
        <ContentTemplate>
        <table>
        <tr>
        <td>
            <asp:RequiredFieldValidator ID="rfvSearch" runat="server" ErrorMessage=""
            ControlToValidate="rtbSearch"
            ValidationGroup="SearchRequired"></asp:RequiredFieldValidator>
            <br />
            <telerik:RadTextBox ID="rtbSearch" runat="server" Width="25em" MaxLength="100"
                ValidationGroup="SearchRequired"
                EmptyMessage="Search for a Fee Definition" Skin="WebBlue" />
            <telerik:RadButton ID="rbSearch" runat="server" Text="Search"
                onclick="rbSearch_Click"
                ValidationGroup="SearchRequired" />

        </td>
        </tr>
        <tr>

Hello Jr,

Note that The RadDock is not a standard control and you can't update only one RadDock separately or inner for it controls. If you want to make an Ajax call you should update the parent RadDockZone. 
Please give this a try and let me know if the loading panel will appear.
