AjaxSettings for Page trying to access UserControl in MasterPage

[Scott]

On my page I have a radgrid "rgdProductList" and I'm trying to add ajax settings to update a UserControl "Navigation" within the master page. Inside the UserControl "Navigation" I have a div with an id of "nav"

On Master Page:

<%@ Register Src="../Modules/Controls/nav.ascx" TagName="Navigation" TagPrefix="uc1" %>
...
<uc1:Navigation ID="Navigation" runat="server" />

On "Navigation" UserControl:

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="nav.ascx.vb" Inherits="Modules_Controls_nav" %>
<div id="nav" runat="server" class="navigation">
    <!-- Inner Content Goes here -->
</div>

On "Products" page (which inherits that master page above): [NOTE: rgdProductList is a radgrid on the products page]

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    Dim oNavigation As Modules_Controls_nav = DirectCast(Me.Master.Controls(0).FindControl("Navigation"), Modules_Controls_nav)
    RadAjaxManager.AjaxSettings.AddAjaxSetting(rgdProductList, oNavigation)

    Dim oNav As HtmlGenericControl = DirectCast(Me.Master.Controls(0).FindControl("Navigation").FindControl("nav"), HtmlGenericControl)
    RadAjaxManager.AjaxSettings.AddAjaxSetting(rgdProductList, oNav)

End Sub

As shown above, I tried adding AjaxSettings to both the UserControl itself as well as the inner div tag. I also tried adding a ajaxsetting to the master page, but it generates a radcodeblock error. I also tried wrapping the div tag in a update panel to no avail.

Any help on this subject would be GREATLY appreciated. NOTE: all other ajax settings on the page work fine and I don't see any JS errors. I tried adding a radloadingpanel and it did not show up for these ajax settings, but did for all other ajax settings on the page.

Hi Michael,

Please go through the following help article which elaborates on this subject and see if it helps.

Additionally, to avoid the radcodeblock error simply wrap your JS code around RAdCodeBlock/ RadScriptBlock. For more details please visit: http://www.telerik.com/help/aspnet-ajax/ajxradscriptblockradcodeblock.html
