    I'm having an issue updating content on a master page, using strongly typed controls. 

    On my master page, i have public classes that expose the .visible property of an asp.net panel, the content page sets the param to true or false. I have a radajaxmanager on master page and proxy on sub page, however I am unable to ajaxify the panels on the master.

    For the solution I would prefer not to use FindControl()

    Can someone point me in the correct direction?

    Hi Dan,

    For accessing the Master Page control in Content Page you have to define some public properties in the master page as follows.

    Master Page ASPX:
    <asp:Panel ID="Panel1" runat="server">
        <asp:TextBox ID="TextBox1" runat="server">
    <asp:Label ID="Label1" runat="server" Text="demo">

    Master Page C#:
    public Panel pnlDemo
            return Panel1;

    Thus in the content page try the following code snippet to access the control.

    Content Page C#:
    protected void Page_Load(object sender, EventArgs e)
        if (!IsPostBack)
            //RadAjax_PanelAjax is the class name of the master page
            RadAjax_PanelAjax master = Page.Master as RadAjax_PanelAjax;
            master.pnlDemo.Visible = false;
