It's hard to tell exactly what your problem is, but I think you are saying that you can't access MasterPage objects from the Page that is using the master? If so, try adding <%@ MasterType VirtualPath="~/Master.Master" %> to your aspx page.

Master.treevew1  //  Here I cannot access masterform objects

You cannot directly access controls of master page.

You need to either strongly couple the master page with child page in page tag OR you need to use FindControl to find the control in master page OR you can expose a public property in Master page that exposes the needed server control.

Pick the one you like.
