Hello,
The following exception is being thrown from the winchart and I don't understand why. Any help will be greatly appreciated.
I don't understand how it is setting a null value for the tooltip.
Thanks,
Mike
i think this happens in rare circumstances when the chart's tooltip ends up getting disposed before the top level control is painted. i was never able to reproduce this problem, but i did fix the potential null reference for another forums customer.
the change was made on 1/20, so it didn't make it into the hotfix that's currently available on our website. however, it will be fixed in the next hotfix as well as the 9.1 release.
Is there a way I can get my hands on this fix for 8.3? I have a production product we are putting in the field next week and my manager would like this gone before customers actually see it. If there are steps to go through to get this item, I will do them.
if your subscription includes source code, you could just download the source and add the null check in IGWinTooltip.AddToControlsCollection.
Infragistics Developer Support (http://infragistics.com/gethelp) might be able to provide you with a private hotfix build if there is one available.
Thanks for the help.
