I have this “little” problem:

I’m trying to use AjaxControlToolkit (AjaxControlToolkit.dll 3.5.40412.2) in my custom module.

I tring to use the CalendarExtender extender for example, because is veri esay to implement.

First I First I change the target FrameWork to .NET Framework 3.5 this will enable the Ajax control tool kit controls tab.

Then I add add a ToolkitScriptManager from the AjaxControlToolkit tab

After that I add a textbox from the standar Tab to my page (ascx) and then a CalendarExtender from the AjaxControlToolkit tab.

I configure the calendar extender so the result is this.

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">

    </asp:ToolkitScriptManager>

<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>

<br />

<asp:CalendarExtender ID="CalendarExtender2" runat="server" TargetControlID="TextBox2">

</asp:CalendarExtender>

If you put this code in a regular web site project and run the project it will work. When you click on the textbox I will display the calendar.

If you run this code in your DNN module you’ll get the fallowing error:

A critical error has occurred.
Object reference not set to an instance of an object.

If I change ToolkitScriptManager and use this one ScriptManager

 

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>

<br />

<asp:CalendarExtender ID="CalendarExtender2" runat="server" TargetControlID="TextBox2">

</asp:CalendarExtender>

I will get this error

A critical error has occurred.
Object reference not set to an instance of an object.

And finily if I use only the CalendarExtender 

<ajx:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="TextBox1"

    PopupButtonID="btnInUpdatePanel">

</ajx:CalendarExtender>

I get these java script errors

Those any one knows how to manages this issue o knows how to work in DNN with the AjaxControlToolkit ?????

Same problem here.   No ajax on my site is working.   Running DNN.5.06.1  ... VS 2008.   Didn't solve the problem.   VS 2008 cant access the web.config and my module doesn't seem to register the 'AjaxControlToolkit'.    VS reports an 'unregistered tag'.

Does anyone have a solution ?

Hi again... this is funny. I just could make it work.
I mean: I have an VIEW.ASCX control file which is part of a custom Module I've been dealing with, and I managed to make the Calendar Extender appears and work.

I guess you wanna know how. :)

1. I removed all the AJAX controls I had in my "AJAX Control Toolkit" tab in my Visual Studio 2008 (not Express). I also removed the tab.
2. I downloaded something I guess is a previous version of the ajaxcontroltoolkit.dll, from http://ajaxcontroltoolkit.codeplex.com/releases/view/33804
(I found that sugestion here http://dnnblog.lexicoreinc.com/2010/12/dotnetnuke-5-and-ajax-for-net-35.html )
3. I unzipped the downloaded file (oops, I forgot to "unlock" it, as the asp.net site told me. Anyway... it worked).
4. I took the AjaxControlToolkit.dll file and put it in "C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE". (I did that because I alway saw that VS tried to look for the file there).
5. In VS again, with my view.ascx opened, I created the "AJAX Control Toolkit" tab in the toolbox, and then right-clicked below it to "Choose elements", went to the folder I said before and choose the AjaxControlToolkit.dll.
6- Once VS populated the toolbox, I selected a textfield from my ascx, clicked on the little arrow it has, selected "Add externder", there it was my very expected "Calendar Externder", I selected it, and saved the page. Generate it, and gave it a try.

The result: ¡The Glory! - clicking on the textbox, the calendar pops up and once I select a date, it sends it to the textbox.

Now I have to see if I can make it work in my production environment.
