Hello i have a dropdownlist on my masterpage.

But how can i select the index of that dropdownlist from my content ?

I thought to add the index to a session but de page load event is done before the index changed event ?

You can locate the DropDownList by running Master.FindControl

Dim ddl As DropDownList = DirectCast(Master.FindControl("DropDownList1"), DropDownList)
ddl.SelectedIndex = 3

Postback events are always raised after Page_Load.

You can alos create a property in the master page and acess it through the content page. More OOP.

Can you expand on the   property in the master page   I have a master page that contains:

<div id="mainmenu">
   <ul>
       <li><a href="<%=Page.ResolveUrl("~/default.aspx")%>" id="tab_Home" class="selected">Home</a></li>
       <li><a href="http://forums.asp.net/AddPost.aspx?PostID=1388327#" id="tab_Services">Services</a></li>
       <li><a href="http://forums.asp.net/AddPost.aspx?PostID=1388327#" id="tab_Contact">Contact</a></li>
       <li><a href="<%=Page.ResolveUrl("~/About.aspx")%>" id="tab_About">About</a></li>
       <li><a href="<%=Page.ResolveUrl("~/AboutSelected.aspx")%>" id="tab_AboutSelected" class="selected">AboutSelected</a></li>
                <%if(Page.User.IsInRole("Administrator")){ %>
        <li><a href="<%=Page.ResolveUrl("~/admin") %>" id="tab_Admin">Admin</a></li>
              <%} %>
   </ul>
</div>

The tab_Home is set for  class="selected"  (the default page) and when another tab is clicked I would like to know how to set the Master Page "class" for the tab_Home to not-selected???  and then set the appropriate tab to  "selected"

Something like  Master.mainmenu.tab_Home.selected=""   and then

                        Master.mainmenu.tab_About.selected="selected"   in the Page_Load of the About page...

This will (I hope) move the Highlight from the tab_Home tab to the tab_About tab...

Can you please tell me how to do this in C# 

Thanks,

Paul
