Linking Code Behind to the IsPrime Web Service Consumer

We showed you in Column 114 how to consume the IsPrime Web service from an ASP.NET page. Let's now split the presentation from the business logic by putting the JScript .NET code in a separate Code Behind file. 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.
