Memory Leak issue in group by row
posted

when I use group-by-column feature on a column that had many different values (which will create many sub-rows), the application simply hung, and when I stopped, I got the following on the call stack.

And, another question is that even I did "SuspendSummaryUpdate()" on grid, does this get resume by default, or once I suspended, does it remain suspended?

(Top is the when I broke)

    Hi tboy79,

    I am seeing what looks like memory leaks from Infragistics Grid and the PerCederberg components are listed too so think it might be related to your post. Did you manage to get this logged as as an issue and fixed? If so, can you remember what the fixed version was? I am using winforms 9.2

    Thanks

    Javier

    It's not really possible to determine the cause of this issue on the forums, so what you should probably do is submit the issue to Developer Support along with a sample demonstrating the issue so that they can look into it, or see if the issue has already been addressed.  One thing to try before you do this is to make sure that you have applied the latest hotfix.

    As for your question about SuspendSummaryUpdate(), they will not be resumed until a call to ResumeSummaryUpdates is made.
