Why this simple example of ajaxToolkit:DynamicPopulat
Posted on 2008-10-18
I just created an example of ajaxToolkit:DynamicPopulat
<form>
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" />
<ajaxToolkit:DynamicPopulateExtender ID="dpe1" runat="server"
ClearContentsDuringUpdate="true"
TargetControlID="txtContent" ServiceMethod="HelloWorld" ServicePath="OpenTextFile.asmx.vb" />
<asp:Panel ID="pnlEditor" runat="server" >
<input type="button" onclick="$find('dpe1').populate();" ID="Button1" value="Button" />
</asp:Panel>
<asp:Label ID="txtContent" runat="server" Text="Label"></asp:Label>
</form>
And ere is the service file:
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
Imports System.Web.Script.Services
<System.Web.Services.WebService(Namespace:="http://tempuri.org/")> _
<System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<ToolboxItem(False)> _
Public Class OpenTextFile
Inherits System.Web.Services.WebService
<WebMethod()> _
Public Function HelloWorld() As String
Return "Hello World"
End Function
End Class

Hi,
The service must be registered as a scriptservice in order to be consumable by script (i.e. Ajax..), please add the following line on top of your service declaration:
<System.Web.Script.Service

Hi,
I read through the documentation, it seems the method call requires an arbitrary string parameter (contextKey) which You have not included in your method. Try changing Your method to:

Browser hick-up...
Try changing the method to:
<WebMethod()> _
Public Function HelloWorld(ByVal contextKey As String) As String
Return "Hello World"
End Function
and see if that makes a difference.

Hi,
Please review the attached snippet, this code works just fine for me. If You still can't get it working, I suggest maybe watching the HDI video by Joe Stagner on the DynamicPopulate extender for some tips on how to implement it.

Your code does not work for me!
By the way I opened FF's Error Console I got the following JS error: $find('dpe1') has no properties. Your code does not give any error but it does not work.

Hi,
Hmm, I do not use "$find('dpe1')" anywhere in my provided code, have You left a javascript onclick method anywhere or made any changes to the code I provided?

Hi,
My code definately works, tried it out in IE, FF and Safari. If it's not running for You something must be misconfigured in your project / solution and/or dev. environment. You can have a look at http://norrbom.nu/movies/WorkingCode.swf.html to see an swf movie showing my code build and run on IE, FF, Safari without any problems.
