Well, I did finally get this to work via the KYNOU.com web site and
trying the tutorial:
http://www.kynou.com/GetTutorial.aspx?TutorialID=51
This is a little bit different from what I was doing, but the concept
is the same.
I didn't use a separate class file, but put the Ajax Method in the code
behind. The app name is CSS:
--Start code behind
Public Class WebForm1
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
AjaxPro.Utility.RegisterTypeForAjax(GetType(WebForm1))
End Sub
<AjaxPro.AjaxMethod()> Public Function GetStateName(ByVal
stateInitial As String) As String
Select Case stateInitial.ToUpper()
Case "CA"
Return "California"
Case "NY"
Return "New York"
Case "IL"
Return "Illinois"
Case Else
Return "What tha'!"
End Select
End Function
End Class
--End code behind
--Start HTML for WebForm1
<HEAD>
<title>WebForm1</title>
<meta name="GENERATOR" content="Microsoft Visual Studio .NET
7.1">
<meta name="CODE_LANGUAGE" content="Visual Basic .NET 7.1">
<meta name="vs_defaultClientScript" content="JavaScript">
<meta name="vs_targetSchema"
content="http://schemas.microsoft.com/intellisense/ie5";>
<script language="javascript">
function getStateName(obj)
{
CSS.WebForm1.GetStateName(obj.value,CallbackFunc);
}
function CallbackFunc(res)
{
document.getElementById('txtStateName').value = res.value;
}
</script>
</HEAD>
<body MS_POSITIONING="GridLayout">
<form id="Form1" method="post" runat="server">
<div>State Initial:</div>
<asp:TextBox id="txtStateInitial" style="Z-INDEX:"
runat="server"
onblur="getStateName(this);"></asp:TextBox>
<div>State Name:</div>
<input type="text" id="txtStateName">
</form>
</body>
</HTML>
--End HTML for WebForm1
