title: Form tag on master page and Content pages
body: <p>I have a ASP.NET application with one Master Page and Multiple content pages. </p>
  
  <p>This is a start of Master Page </p>
  
  <pre><code>&lt;body&gt;
  &lt;form runat="server"&gt;
      &lt;asp:ScriptManager runat="server"&gt;
          &lt;Scripts&gt;
              &lt;%-- Scripts Omitted --%&gt;
          &lt;/Scripts&gt;
      &lt;/asp:ScriptManager&gt;
              .
              .
              .
              .
              .
  </code></pre>
  
  <p>Now, i have a Registration page with a form to submit. Here is the start</p>
  
  <pre><code>&lt;asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server"&gt;
  &lt;br /&gt;
  &lt;form id="Form1" runat="server"&gt;
  &lt;div class="register"&gt;
      &lt;br /&gt;
              .
              .
              .
  </code></pre>
  
  <p>Whenever I tried to run the <code>Register.aspx</code> page, it gives me error as : <code>A page can have only one server-side Form tag.</code> and I know its because I have a Form tag on Master Page. Now if I tried to remove the form tag from Master Page (Which I thought unnecessary), I got error as : <code>Control 'ctl01' of type 'ScriptManager' must be placed inside a form tag with runat=server.</code></p>
  
  <p>My Question is : <strong>How can I use <code>Form</code> tag on Master as well as on content page without removing <code>ScriptManager</code>. Or is there any alternative to accomplish this ?</strong></p>
