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
