The first error is:
A run time error has occured.
Do you wish to debug?
Line: 3
Error: Syntax error
(This error is repeated 4 times)
The second error is:
Microsoft JScript runtime error: 'AjaxData' is undefined.
(I know exactly where this error is occuring, and believe that it is
related to the fact that the class AjaxData has not been properly
registered.
Here is the code that I am using:
The AjaxData class - saved in the App_Code folder of the project:
Imports Microsoft.VisualBasic
Imports System.Data
Public Class AjaxData
'Reference to web service that accesses the database
Dim myAjax As New wsAjax.AjaxProcessData
<AjaxPro.AjaxMethod()> _
Public Function GetSubType(ByVal type As String) As DataView
GetSubType = Nothing
Dim dvwSubType As DataView
dvwSubType = New
DataView(myAjax.GetSubType(type).Tables("SubType"))
Return dvwSubType
End Function
End Class
My Javascript file ("AjaxDataProvider") - saved in a folder called
scripts:
function LoadType(identifier)
{
var type =
identifier.options[identifier.selectedIndex].value;
AjaxData.GetSubType(type, LoadType_CallBack);
}
function LoadType_CallBack(response)
{
//if the server-side code threw an exception
if (response.error != null)
{
//we should probably do better than this
alert(response.error);
return;
}
var subTypeCode = response.value;
//if the response wasn't what we expected
if (subTypeCode == null || typeof(subTypeCode) !=
"object")
{
return;
}
//if the user choses other disable the second
drop-down.
switch (document.getElementById("ddlOrgType").value)
{
case "Other":
document.getElementById("ddlSubType").style.display="none";
document.getElementById("txtOther").style.display="";
document.getElementById("ddlSubType").options.length = 0;
return;
case "Select Organisation Type":
document.getElementById("ddlSubType").style.display="";
document.getElementById("txtOther").style.display="none";
document.getElementById("ddlSubType").options.length = 0;
return;
default:
document.getElementById("ddlSubType").style.display="";
document.getElementById("txtOther").style.display="none";
}
//Get the states drop down
var SubTypeList =
document.getElementById("ddlSubType");
SubTypeList.options.length = 0; //reset the states
dropdown
//Remember, its length not Length in JavaScript
for (var i = 0; i < subTypeCode.length; ++i)
{
//the columns of our rows are exposed like named
properties
SubTypeList.options[SubTypeList.options.length] =
new Option(subTypeCode[i].SubType,
subTypeCode[i].SubType);
}
}
The page_load event for my web page (Subscriptions):
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
AjaxPro.Utility.RegisterTypeForAjax(GetType(AjaxData))
End sub
The section out of my web config file:
<httpHandlers>
<add verb="POST,GET" path="ajaxpro/*.ashx"
type="AjaxPro.AjaxHandlerFactory, AjaxPro.2"/>
</httpHandlers>
located just before the
<compilation debug="true" strict="false" explicit="true">
And the call to the javascript in the source of my web page along with
the reference to the javascript file:
<asp:DropDownList ID="ddlOrgType" onchange="LoadType(this)"
runat="server" Font-Names="Tahoma" Font-Size="XX-Small"
TabIndex="11"
AutoPostBack="True">
</asp:DropDownList>
javascript file located in the <head> of the page
<script language="javascript" type="text/javascript"
src="Scripts/AjaxDataProvider.js"></script>
I am using the AjaxPro.dll which I only downloaded today, and it is
referenced in my bin folder.
