    Trying to get the tooltip to work within a TemplatedColumn in the UltrawebGrid which is itself within a WebAsyncRefreshPanel.  Followed the example for the RadToolTipManager and added controls to the RadToolTipManager's TargetControls collection within the Grids InitializeRow event handler. 

    The issue I have is that the AjaxUpdate event handler on the RadToolTipManager never fires.  The RadToolTipManager's TargetControls collection gets populated correctly with the link control ClientID from within the TemplatedColumn.   So is RadToolTip on a TemplatedColumn in a UltrawebGrid within a WebAsyncRefreshPanel using the RadToolTipManager just a bad idea or am I missing something simple?

    Hi Ciaran,

    If you followed the RadToolTipManager example and set all ID's OK there should not be any problem.

    Do you actually see the tooltip shown like a little rectangle when you hover over an item?
    If you don't then probably the problem is not with the OnAjaxUpdate not firing, but the tooltipmanager not being fed with proper client ID's.

    Please check whether the ID's do match existing elements on the page by examining the client-side page source ("View Page Source" browser option).

    In case you are not able to resolve the problem, it is best to send us a simple project that reproduces the issue and we will delve further into it.

    Thanks for the response. I have attached sample ASPX/C# code working against Northwind that contains a simulation of what I am doing.

    I have a WARP Panel which contains 2 ASP Panels (one for a search form and the other for the search results grid). Clicking on the button in the iniial visible panel will toggle the panels within the WARP Panel and populate the grid in the other panel. In this scenario, the ToolTip does not work and gives a JavaScript error “Sys.InvalidOperationException: The PageRequestManager cannot be initialized more than once” when the cursor is over the Order column (which shows the ClientID for the links within the Grid TemplatedColumn).

    Also, I noticed that the ToolTip when working (by populating and showing the grid on initial page load) does not position itself correctly when the page is scrolled vertically. It seems to stop at the initial page footer.

    Thanks for your assistance.

    Hello Ciaran,
    Based on the information you provided, I was able to reproduce the problem with the position of the RadToolTip when you have scrolled down the page and forwarded it to our developers. We will fix it as soon as possible.

    However, for the problem with the UltrawebGrid, we will need a whole test project, that we can run without modifications and that is why I will ask you to open a new support ticket and send us such a project as an attachment. As soon as we have a project, we will do our best to find the cause for the js error.

    Kind regards,
    the Telerik team
