Hi,
I have a form that contains several panels, each with a chart on it (actually each chart is on it's own form and an instance of that form is added to each panel). I have the following two problems with tooltips, which may a may not be related:
1. The tooltip appears about 2 inches (!) below the mouse position, this deosn't seem right and looks ridiculous.
2. When I set the tooltip overflow option to ChartArea (or ClientArea) the tooltips always appear on the first chart, even when I hover over a data point on one of the other charts!
Any ideas on what's causing these problems and how I can fix them?
I'm using version 8.3 with Visual Studio 2008.
Thanks.
Brian
i wasn't able to reproduce this problem, although i have seen it happen before (and fixed it) in some dockmanager or MDI-based applications. could you provide some sample code or a sample project?
if you look at the "options" tab when composing a message on these forums, you should see an option to upload attachments.
you can also send this directly to infragistics developer support at http://infragistics.com/gethelp
I have attached a project that shows the problem.
It was working correctly when it was a single form application, but when I made the form (From1) an MDI child the tooltip suddenly moved down about an inch (although it's worse than this on my own project)! I noticed that If you have the child window maximized the tooltip looks ok (although it might be a little too low), but when you restore the child to it's normal position (not maximized) the tooltip moves down noticeably!
I then added an UltraTabbedMdiManager to the main form (I use this in my application), which defaults to showing the child windows as tabs, and in this mode the tooltips were also down about an inch.
So the problem is definitely to do with MDI support.
I also tried setting the chart tooltip Overflow property to ChartArea this caused the tooltip to always appear in the top chart, even when hovering over a data point in the bottom chart!
