I'd like to show a tooltip while hovering over a RadGrid row. This functionality works well until displaying the tooltip with RadToolTipManager. If I hover over a row, the tooltip appears short. It disappears after a while automatically. The page is ajaxified as well as the UserControls on it. How can I get tooltip stayed on the page?
Regards,
Adi

You can set the HideEvent property of RadTooltip as per your requirement.
ASPX:
<telerik:RadToolTip HideEvent="ManualClose" ID="RadToolTip3"
The HideEvent property is an enum and can take the following values, which names describe the effect that you set:
- Default
- FromCode
- LeaveTargetAndToolTip
- LeaveToolTip
- ManualClose
-Shinu.
Shinu has provided the relevant information for your question. What I can add is to suggest to examine the demos below where you can directly test the actual behavior with the different settings:

It was the time the databinding occurs. If the tooltip was displayed, the grid was rebind and therefore the TargetControls collection was recreated. I have refactor the binding logic and now the ToolTip remains. But now I get an other error:
---------------------------
Message from webpage
---------------------------
RadToolTipManager response error:
Exception=Sys.WebForms.PageRequestManagerServerErrorException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Update: I have solved the issue. The sample links from Svetlina were very useful. The PageRequestManagerServerErrorException was resolved by refactoring the AJAX configuration. It works fine, now.
Thanks!
