    Hi Zhao790,

    According to your description, I suggest you could use the traditional Div with Css to achieve the purpose of two-column layout, and then uses IFrame tags to implement embedded web pages.

    I have made a demo, wish it is useful to you.



            <div id="div">
                <div id="div1">
                    <asp:TreeView ID="TreeView1" runat="server">
                            <asp:TreeNode NavigateUrl="~/WebForm1.aspx" Target="Right" Text="Home" Value="Home">
                                <asp:TreeNode NavigateUrl="~/WebForm2.aspx" Target="Right" Text="New Node" Value="New Node"></asp:TreeNode>
                                <asp:TreeNode NavigateUrl="~/WebForm5.aspx" Target="Right" Text="New Node" Value="New Node"></asp:TreeNode>
                <div id="div2">
                    <iframe id="Right" name="Right" runat="server" frameborder="0" scrolling="auto" width="100%" height="90%"></iframe>


            * {
                margin: 0;
                border: 0;
                padding: 0;
            #div {
            #div1, #div2 {
            #div1 {
                flex:0 0 200px;
                border: 1px solid #00ffff;
            #div2 {
                flex:1 1;
                border: 1px solid #0094ff;

    We could use the iframe name to assign the src property.

    //iframe loading page by code behind.
    this.Right.Attributes.Add("src", "/WebForm1.aspx");

    Feel free to let me know if you have any questions.

    Best Regards
