TTMSFMXGrid Memory Leak

FMX TMS FMX UI Pack
1

I?ve already posted this memory leak months ago and it is here again:
1. Memory leak occurs after deleting row (grid.DeleteRow(aRow)) with ReportMemoryleaksonshutdown := true
2. It only will happen if cells within this row where Background-Color Changed
e.g. grid.Colors[ACol, ARow] := TAlphacolors.XX

Reproducable steps:
1. Place TTMSFMXGrid on Form
2. Do some Background Colors on a row on some cells
3. Delete this row
4. Close + Memory Leak (TCellProperties x Amount of Background Cell-Color Changes in deleted rows)

Hi, 


We have placed a TTMSFMXGrid on the form, and used the following code but are not getting memory leaks when pressing delete on the keyboard removing the rows with the colored cells so please send us code that can reproduce the memory leak so we can investigate this here.

  ReportMemoryLeaksOnShutdown := True;
  TMSFMXGrid1.Colors[2, 2] := claOrange;
  TMSFMXGrid1.Colors[2, 5] := claRed;

Kind Regards, 
Pieter

Ok, try this:
..
grid.hidecolumn(4) in same row !
+ And next try to delete multiple times with key del or Delete(ARow) and AV !

ReportMemoryLeaksOnShutDown := true;
    for i := 0 to grid.Columns.Count - 1 do
      grid.Colors[i, 2] := TAlphacolors.Lightgray;
    grid.Cells[2, 2] := 'ABCj lkasjd lkasjd lkasjd lkasjd lkasj dlkasj dlasj dlkjas lkdjas';
    grid.FontColors[2, 2] := TAlphacolors.Blanchedalmond;
    grid.FontStyles[4, 2] := [TFontStyle.fsBold];
    grid.HideColumn(4);

The last update didn?t address the open leak + AV. Will it be fixed soon?

Hi, 


We have investigated this here and have applied a fix for these issues.
The next version will address this.
