We are using UltraChart 8.3 for windows. Recently we are experiencing a problem on display Tooltips.
The tooltips can be correctly displayed in our main window. But when I create a new window on top of the main window, and display chart in this new window, tooptip just won't show. I can only see a circle at the data point, but not the tooltip text. There is no difference on how the chart gets created and displayed in the main window or floating window.
I suspect it's related with the parent of the forms.
Any clue?
Thanks,

tooltip positioning and parenting is an area that we often find exceptions to - that is, we get a lot of reported cases were an app's window architecture causes the tooltip parenting or positioning to fail.
so please test this with the latest available service release, as recent fixes might resolve the problem for you. if the problem persists, please contact us with steps to reproduce or a sample project so we can fix the problem in our code.
I have the same problem. I have tested this using the latest available release and the problem is still there i.e. when the window is docked the tooltip is displayed, when it is undocked (floating) the tooltip is not displayed.
I am working as a freelance software developer for a very large corporation utilising infragistics controls in its internal bespoke software applications. Is there someone I can start an email dialogue with at Infragistics?
Thank you for your suggestion. The problem i relate to is a generic problem. I originally encountered this problem with the Chart FX graphing control. After some investigation I realised that the problem was not peculiar to this particular control. I put this simple solution together to illustrate the problem. Put simply Tooltips do not work in undocked windows for several control types, inlcuding, as I have shown in the sample solution, the most basic of .NET controls, e.g. labels.
sorry i didn't finish my post.
I was going asking, by looking at the control list from the from, i can see it's Infragistics Tooltip, and where is the WinDockManager in place?
Thanks
I am using UltraChart.
musakhan:
your sample project uses a Windows Forms ToolTip with the UltraDockManager; the WinChart is not involved. for an answer, please post your question in the WinDockManager forum: http://community.infragistics.com/forums/84.aspx
i can tell you that using the Infragistics ToolTip instead will resolve this problem:
new UltraToolTipManager().SetUltraToolTip(lbl, new UltraToolTipInfo("TooltipForLabel", ToolTipImage.None, "", DefaultableBoolean.True));
I attach a Visual Studio 2008 solution which demonstrates this problem.
To reproduce the behavior:
1. Start of the application and place the cursor over the only label. You should see a tooltip appear.
2. Undock the pane containing the label and place the cursor over the label, you will see that the tooltip no longer works.
