Master page managing ContentPlaceHolder

Question

Hi, this is my issue:

I have a master page in C#, where I have this code:

<div style="width: 30%;height: 500px;float:left">
        <asp:ContentPlaceHolder ID="cphMenu" runat="server">
        </asp:ContentPlaceHolder> 
    </div>


    <div style="width: 65%;height: 500px; float:right">
       <asp:ContentPlaceHolder ID="cphMain" runat="server">            
       </asp:ContentPlaceHolder>        
    </div>

As you can see, I have two ContentPlaceHolders, the first one is the left menu (cphMenu), and the second one is the page itself. So, I want to click an item from the menu (the menu is a treeview) and load that specific page on the second contentplaceholder (cphMain).

How can I get that behaviour??

Thanks in advance.

Answer 1

create content pages for each 'specific page', make them use your master page, place correct content into the cphMain

then in treeView add URLs for these pages.

Master page is like a template for content pages, so it will fill the content from content page into placeholders.
