The title pretty much explains it. I have the toolscriptmanager on my master page like so:
<ajaxToolkit:ToolkitScriptManager runat="server" />
and in my web.config I have the name declared, like so:
<add tagPrefix="ajaxToolkit" assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" />
Microsoft JScript runtime error: Sys.ArgumentException: An element with id 'form1' could not be found.
Parameter name: elementOrElementId
... followed by
Microsoft JScript runtime error: Unable to set value of the property 'value': object is null or undefined
I had recently moved all my code manually from one project to another, where everything went smoothly and worked fine but I have only just now noticed this error. I have since ripped out all the ajax, redownloaded the latest version using nuget and put
it all back into my project. The problem is still there. Does anyone know what might be going on? I can show you the lines of script that are causing this error as well if you like.
*edit* the script manager is directly inside the form tag with id "form1" as is standard (in a master page).

Hi Ranjeet, thanks for your response.
On doing a view source i can see there is only one "form1". I'm confused. Not even sure how else to troubleshoot this...

I have it fixed. This is rather ridiculous, you'll love it!
When putting a script file into a page, make sure it is <script></script> and not <script />! Not only did this stop all my postbacks working, it also wrecked the VS 2010 designer AND caused ajax control toolkit to throw a load of errors on page load.
Is my understanding incorrect, but shouldn't <script /> be acceptable?

Thank you. I actually signed up just to thank you for this. This little error had been bugging me for quite some time - especially in debug mode. (pun intended)
So, Timmy, thanks, and I agree - <script /> should be acceptable - but I'm sure they'll address it when they have time.
