for my Web Application (Visual Studio 2010 .NET 4.0 Framework w / Telerik Rad Controls for ASP.NET AJAX Q2 2010 NET 40)
I am replicating the exact same functionality as in the Example above with a repeater control, but when I mouse over the Repeater the tool tips shows the me information about another image within the tooltip.
For Example
Mouse Over Image 4 = Tooltip shows me information about Image 8
The only repeater item that works consistently is the first repeater item that is rendered
***It seems that the when I mouse over the Repeater image ToolTipManager calls the webservice method multiple times
I have isolated everything that could cause a problem. I have checked my webservice call to the database and it is working fine.
Looks like some issue with the control not sure what is happening here.
Attached is the code

I am not sure what could cause the same code to work at our side and not at yours. However, what I can suggest is to set UniqueID to the user control where you render it in the WebService and test again.
If this does not resolve the problem on your side, please provide an isolated sample demo where we can observe the issue and we will do our best to help.

Did you resolve this issue? If so, what was the solution? I have a simliar problem. Basically I can see in fiddler the tooltipmanger gets the tooltip for every single target control -- then it seems to display them randomly.
Thanks,

I was able to resolve the problem.
I was using VS 2010 with .NET Framework 4.0, and I ran into several issues with VS 2010 and .NET Framework 4.0 it was very quirky and slow. VS 2010 w/ .NET 40 was just not behaving well - during debugging it would overwrite my code, during programming it would reformat my code, debugging was slow and painful, and it did not play well with AJAX or 3rd party controls.
So I switched to VS 2008 and now instead of using a webservice to load the tool tip on demand, I simply preloaded loaded the tool tip on the page load event. This resloved my problem.
I have the flexiblity in my app to not using a webservice, When I switched my project to VS 2008 I did not try to use webservice to load the tool tip on demand but I think it would have worked in VS 2008 and .NET Frame 3.5
Hope that helps let me know if you have any other questions.
We were recently able to reproduce and find the reason for the problem and it comes from the fact that MicrosoftAjax.js file for version 4.0 was referenced and it replaces some of the built - in js functions with others and in the case in particular it introduces the observer context which is new in ASP.NET 4.0. We already found and fixed another problem related to this but we will need some additional time to find a suitable way to fix this problem in particular.
If this is the case on your side, what we can suggest is to reference an older version of the js file as a temporary solution and once we resolve the problem, I will write back to you and you will be able to switch back.
In case this is not the case on your side, please provide more details how to reproduce the issue and we will do our best to help.
