ASP.NET Navigation and Validation quesitons

Two things I am trying to figure out.

Question 1.
A site map comes from the master page.  The site map is displayed in a tree view.  How can I disable the tree view until there are no more pages errors.

Question 2.
Both the current and prior page use  MasterPageFile="~/Site.Master"
And
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1"

Page 1 has a control named TextBox1.

Why does this PageLoad() code never find control TextBox1?
{
   ContentPlaceHolder cp = ((ContentPlaceHolder)PreviousPage.Master.FindControl("ContentPlaceHolder1"));
           string fname = ((TextBox)cp.FindControl("TextBox1")).Text;
           valuesFromPriorPage.Text = fname;
}


Thanks

Q1: It's not clear what are you trying to achieve, but I'll try a response:
 - change in code visible =false for tree and change it back when the page is free of errors or
- add  Page_Error event in page and hide the tree if there is any error
http://msdn.microsoft.com/en-us/library/ed577840.aspx
- use try/catch for the code that raises error and manage tree visibility in catch code

Q2: You are probably searching the wrong container:
- try to find control recursive

- check if indeed you need to search PreviousPage or directly the Master of the current page:
 ContentPlaceHolder cp = ((ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1"));
