Hello,
it seems that the TooltipManager control does not save the dynamically added ToolTipTargetControls in its viewstate, correct?
Instead after a postback it works like the default behaviour without assigned TargetControls (all elements with an assigned 'title' property on the page are affected)
Is this behaviour intended?
The problem is critical when the TargetControls are assigned during DataBound events on list items. It does not make sense to reassign them (rebind) on every postback.
Any ideas or workkaround?
Kind reagrds.

Hello Rainer Friedl,
We are not aware of this issue. As you can see, your scenario is very close to one of our online examples, where we add the TargetControls in the repeater1_ItemDataBound handler.
Could you please prepare and send us a simple project, demonstrating this behavior?
Kind regards,

I am facing 2 issues in ths code,
1) I have a template column with an image button in the RADgrid. On click of this button a page postback happens, and tooltip does not work.
2)For this grid am using a css stylesheet to display decorated grid and a custom tooltip. But when I check this page on IE, the tooltip is not showing proper style, but when I use inbuilt skin as I mentioned in Line number 5 in above code(skin="Glassy") am getting tooltip with desired custom style.
I dont know how to post the whole project so I am sending a code snippet along with this. Please let me know is this possible to post my whole sample project in this forum.
kindly reply for these queries as I am desperately looking for some solution.
Thanks in advance,
Hans.

Hi Hanumesh,
We have fixed the problem, that is being discusses in this thread. Now the TargetControls collection is persisted across postbacks. Please find the attached hotfix that contains that fix. In case you are a customer, please open a new support ticket and we will send you the dev version of the hotfix.
As for the custom skin, please open a new support thread and send us a simple running project as you cannot attach files in the forum.
Kind regards,
Tsvetie

Hi Hanumesh,
I have to mention one additional thing you have to keep in mind when updating your version of the Telerik.Web.UI - you should not change the IDs of the controls you add in the TargetControls collection:
lblContactName.ID = currentRow.Row["CustomerID"].ToString();

With the new Telerik hotfix 612 some of the previous issues have been fixed, However in the same page when I use a Prometheus RadAjaxManager or more than one UpdatePanel, the tooltip doesn't show.
Thanks,

Hello CK,
You approach for passing the ORDERID is very natural.
As for the integration between Ajax and ToolTipManager, please review the other thread you have started with the same question.

HI,
I am able to download the hotfix, and I tried to display tooltip using this hotfix. But still the tooltip is not displaying on postback of the page.
I have replaced DLLs in my bin directory with this hotfix and I have not done any changes to my code which I posted in my previous mail.
I am adding targetcontrols as follows,
in Datagrid_ItemDataBound event.
Please let me know whether I need to make code changes to use this DLL? so that TargetControls of RAD tooltip will persist even after page postback.
Thanks,
Hans.

Hello Hanumesh,
As mentioned before, you should not change the IDs of the controls you add in the TargetControls collection:
lblContactName.ID = currentRow.Row["CustomerID"].ToString();

I am not modifying the target controls IDs of the tooltip. as I already mentioned I am adding target controls only in ItemDataBound event of the grid.
So, when I click on the button which is inside a grid column, the page is getting postback but Tooltip is not working.
Please suggest me.
Thanks,
Hans.

>>As mentioned before, you should not change the IDs of the controls >>you add in the TargetControls collection:
>>
>>lblContactName.ID = currentRow.Row["CustomerID"].ToString();
If I dont change the ID of the controls as mentioned above, how the tooltip manager identify which control is calling the tooltip.
Can you please send me a sample code, so that I can modify my existing code accordingly.
I hope you understood my problem.
I am in need of some solution as soon as possible.
thanks in advance.

Hello Hanumesh,
I suppose you mean that you do not know how to pass the CustomerID to the AjaxUpdate handler of the manager - actually, this is general ASP knowledge and the implementation depends on the application needs. A possible solution would be to use the approach of CK (have a look at the code - it is part of this thread) - in the ItemDataBound handler, add the CustomerIDs to a collection and in the DataBound handler of the RadGrid, save the collection in the Session.
An updated version of the RadToolTip control will be available with the upcoming update, scheduled for 26 June. This update will contain all fixes made to the control and in case you decide to use the new version, you should not have any problems. In case you do, please open a new support ticket and send us a simple running project - we will get back to you as soon as possible.
