Hi:
I have masterpage with a RadScriptManager and a asp:panel (panel used for messages).  In my one of my content pages, I have a RadAjaxPanel.  In my code behind, I am updating the panel pnlErrors.  Sometime the changes to pnlErrors does not display.  Any suggestions?

<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %>
<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<head id="Head1" runat="server">
    <title></title>
    <asp:ContentPlaceHolder ID="head" runat="server">
    </asp:ContentPlaceHolder>
</head>
<body>
    <form id="form1" runat="server">
    <telerik:RadScriptManager ID="masterPageRadScriptManager" runat="server" AsyncPostBackTimeout="180" >
        <Scripts>
            <asp:ScriptReference Path="Scripts/jquery-1.4.1.js" />
        </Scripts>
    </telerik:RadScriptManager>
    ...
    <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="False" />
    <telerik:RadMenu ID="RadMenu1" Runat="server" DataSourceID="SiteMapDataSource1" Width="100%" style="z-index:2900">
        <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>
    </telerik:RadMenu>
    ...
    <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
 
    </asp:ContentPlaceHolder>
    <asp:Panel ID="pnlErrors" runat="server" EnableViewState="false">
    </asp:Panel>
    </form>
    ...
</body>
</html>

Hi Phil,

Could you please elaborate a bit more on your ajax settings.

How does the Panel is updated exactly. Posting some code from the content page and related code behind could help us further research on the problem and provide proper solution.

Hi:

You really do not need to know this info.

I have an interface for both the Master page and the content base page.  I have a list of strings in the master page.  All content pages inherit the content base page. The content pages adds to the list via the base page.  On pre-render, the master page populates the pnlErrors with the data in the list.

Hi Phil,

Note that if you need to update some content on the page during ajax request the same should be added as updated control in RadAjaxManager settings or wrapped by the  RadAjaxPanel control. Please ensure that the panel which should be updated and the ajax initiator are both added into the ajax settings.

Hi:

Thanks for your response.  The answer seems to be RadAjaxManager.  So, I just found the following:
ajax-load-control-from-another-webusercontrol-in-different-masterpage-contentplaceholder
So, I will start from the above content.
