End Sub
</script>

<html>

<form runat="server">
Enter your name: <input id="name" type="text" size="30" runat="server" />
<br /><br />
<input type="submit" value="Submit" OnServerClick="submit" runat="server" />
<p id="p1" runat="server" />
</form>

</body>
</html>

Output Result:
Enter your name:

  

IF you enter your name  "shaohai" in the textbox ,if will show :

Enter your name:

Welcome shaohai! 

In this example we declare one HtmlInputText controls, one HtmlInputButton control, and one HtmlGeneric control (the <p> tag) in an .aspx file (remember to embed the controls inside an HtmlForm control). When the submit button is triggered, the submit subroutine is executed. The submit subroutine writes a welcome message to the p element.
