title: How to get a label value from web user control to a content page using master page
body: <p>I have a web user control book.ascx and a formview:</p>
  
  <pre><code>&lt;formview runat="server" id="fv"&gt;
  &lt;ItemTemplate&gt;
  &lt;asp:Label runat="server" id="bookID" Text='&lt;%# Eval ("bookId") %&gt;' /&gt;
  &lt;/ItemTemplate&gt;
  &lt;/FormView&gt;
  </code></pre>
  
  <p>This formview is databind dynamically.
  Now i have a Content page Default.aspx:</p>
  
  <pre><code>&lt;%@ Register src="Book.ascx" tagname="Book" tagprefix="uc1" %&gt;
  
  &lt;asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"&gt;
  &lt;uc1:Book id="book1" runat="server"/&gt;
  &lt;asp:Label runat="server" id="lblBookId" /&gt;
  &lt;/asp:Content&gt;
  </code></pre>
  
  <p>I want to get the value of the label from web user control to a default.aspx page.
  Whats the best method to solve this issue.
  Thank You.</p>
