Hello,
After the user has been using my application for some time (1-2 hours), some of the controls in the window turn into Red X's and the whole application is unresponsive and has to be ended. Sometimes a 'Not enough storage space is available to process this command' dialogue appears, but often no error dialogue is generated at all. This is happening on both Windows 7 and Windows XP systems.
I am using Infragistics version 12.1.20121.2082, and UltraGrid controls
Is this a known issue in this version? Is there some resource that's being exhausted (garbage collection issue)?
Does the problem always occur after a few hours? Does it ever occur earlier?
If it always takes a while, then it's most likely some kind of memory leak. But whether the leak is something in your code or in the controls is impossible to determine without a sample that we could use to reproduce the issue.
The two controls with red X's in your screen shot are both UltraWinGrid controls?
What kinds of things are you doing with those controls? Are you using images in the cells? How many columns and cells are there? Are you constantly updating the data or the appearances for the rows or cells? Which events are you handling on these controls and what kinds of things are you doing inside those events?
I have a similar problem in Windows 7, Windows 10. A red X is put where the control should be.It happens with Ultragrid, date and ultratap controls. It does not always happen, sometimes it happens only by entering the application, sometimes it happens during work, it is very annoying and I cannot find an explanation because there is not even an error message.
