title: Post data to another aspx page
body: <p>I have simple aspx page that has a form and a input field in it something like below.</p>
  
  <p><strong>//basket.aspx</strong>
      </p>
  
  <pre><code>&lt;input type="text" id="TotalPrice" runat="server" name="TotalPrice" value="100" /&gt;
  
   &lt;asp:button ID="btnBuy" runat="server" Text="make payment" PostBackUrl="~/payment" /&gt;
  
  &lt;/form&gt;
  </code></pre>
  
  <p>This is going to <strong>payment.aspx</strong> but when I debug the Request.Form in the page load of the payment.aspx, I cannot reach the TotalPrice value like Request.Form["TotalPrice"]. What is the best way to make a post to another aspx page to get values ? Why the way I am trying to does not work ? </p>
