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?

<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>

<head id="Head1" runat="server">

<title></title>

<asp:ContentPlaceHolder ID="head" runat="server">

<asp:Panel ID="pnlErrors" runat="server" EnableViewState="false">

</asp:Panel>

</form>

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.

Best wishes,
