Hi dakreyi,

What do you mean? Do you mean that you do not want to load the TreeView Menu for all pages?

If so, you can refer this code,

MasterPage.master:

<%@ Master Language="C#" %>


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">


<script runat="server">


</script>


<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Demo</title>
    <asp:ContentPlaceHolder id="head" runat="server">
    </asp:ContentPlaceHolder>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:TreeView ID="TreeView1" runat="server">
            <Nodes>
                <asp:TreeNode Text="A" Value="A"></asp:TreeNode>
                <asp:TreeNode Text="B" Value="B"></asp:TreeNode>
                <asp:TreeNode Text="C" Value="C"></asp:TreeNode>
            </Nodes>
        </asp:TreeView>
        <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
        

        </asp:ContentPlaceHolder>
    </div>
    </form>
</body>
</html>

Default.aspx:

  <%@ Page Language="C#" MasterPageFile="~/MasterPage.master" Title="Untitled Page" %>

<script runat="server">

    protected void Page_Load(object sender, EventArgs e)
    {
       Page.Master.FindControl("TreeView1").Visible = false;
     }
</script>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
</asp:Content>

Hi Hong-Gang Chen

Thanks for your help.

Although I did not mean that, I was very happy for your reply since you have just taught me a very important thing.

What I meant is: when navigate amnog pages, I would like to see that the Master page does not get refreshed with the pages (ContentPlaceHolder).

That was the case, but since I added the TreeView, when I click on a url to go to another page, the master page content gets also reloded.

I would like to see only the content of pages get changed.

Thanks again

In such case, I think we can use UpdatePanel to solve this problem. Say, put an iframe to an UpdatePanel, and assign the Target property as the iframe's ID, and assign the TreeView control as the trigger, and set the the trigger's event as "Changed", refer the following code,

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <iframe>
            </iframe>
        </ContentTemplate>
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="TreeView1" EventName="SelectedNodeChanged">
            </asp:AsyncPostBackTrigger>
        </Triggers>
    </asp:UpdatePanel>
