JScript .NET, Part IX: Code Behind

The IsPrime Consumer's ASP.NET Page

The ASP.NET page is much shorter when the code is behind. Here is the page for consuming the IsPrime Web service, IsPrimeConsumerForm.aspx:

<%@ Page LANGUAGE="JScript" SRC="IsPrimeConsumerForm.aspx.js" 
  INHERITS="ASPPlus.codeBehind" %>
<HTML>
<HEAD>
  <TITLE>IsPrime XML Web Service Test</TITLE>
</HEAD>
<BODY STYLE="font-size:12; font-family:arial,verdana,sans-serif;">
  <FORM RUNAT="server">
    <TABLE BORDER="0">
      <TR>
        <TD ALIGN="middle"><ASP:TEXTBOX ID="first" RUNAT="server" SIZE="4" 
          STYLE="text-align:'right'"/></TD>
        <TD ALIGN="middle"><ASP:LABEL ID="resultControl" RUNAT="server"/></TD>
      </TR>
      <TR>
        <TD><ASP:BUTTON TEXT="Is Prime?" ID="isprime" OnClick="Submit_Click" 
          RUNAT="server"/></TD>
      </TR>
    </TABLE>
  </FORM>
</BODY>
</HTML>

We have three controls. The first ASP:TextBox control serves for inputting the number to be tested. We use the resultControl ASP:Label to display the result of the check, "is not a prime number" or "is a prime number". The last control is the isprime ASP:Button. When clicked, the function Submit_Click() is called from the Code Behind.
