Hi Team,

We are using _grid.Print(UltragridLayout, PrintDocumemt, RowPropertyCategories) function for printing the grid. However, we found the memory increased everytime there is a printing opertaion and it never goes down even after printing. This caused our system stale after several time large grid pritning.

I did a profiling for the printing. I found ultraColumns will be doubled after we did a printing operation.Below is the stack trace how these duplicated columns are generated.(Tried both on infragistic 8.2 and infragistic 9.1, all have the same issue)

UltraGridBand.InitColumns(UltraGridBand[])
UltraGridBand.InitListManager(BindingManagerBase, string, UltraGridBand[])
UltraGridColumn.InitPropertyDescriptor(PropertyDescriptor, UltraGridBand[])
UltraGridBand.InitColumns(UltraGridBand[])
UltraGridBand.InitListManager(BindingManagerBase, string, UltraGridBand[])
UltraGridLayout.ListManagerUpdated(BindingManagerBase)
UltraGridLayout.ListManagerUpdated()
UltraGrid.PrintHelper(UltraGridLayout, PrintDocument, RowPropertyCategories)
UltraGrid.Print(UltraGridLayout, PrintDocument, RowPropertyCategories)

Any idea what's the reason for this and how to fix it?

Many Thanks,

Xin
