Yes, you did!

NextGrid v5.9.55 works like a charm and fixes the reported issue.

Boki, you're da man!

Please try to completely replace next method in NxGrid.pas

Please tell me how it works now.

 

I'd love to, but I don't have the NextGrid sources. Did my tests with the free D7 component.

Maybe you could provide a beta compilation for D7 with your recent changes.

Hi Boki,

I'm using lastest version of NextGrid v5.9.50 (Delphi 7).

To reproduce the behaviour, I dropped a TNextGrid and a TButton on a Form, added 3 Columns (2 x nxNumberColumn, 1 x nxTextColumn), set these options ([goHeader,goMultiSelect,goSelectFullRow]) and fill the grid with some lines:

procedure TForm1.btFillClick(Sender: TObject);
const NumLines = 10;
var i,k: Integer;
begin
  NextGrid.AddRow(NumLines);
  for i:=0 to NextGrid.RowCount-1 do begin
    k := Random(100);
    NextGrid.Cell[0,i].AsInteger := i;   // Index
    NextGrid.Cell[1,i].AsInteger := k;   // Random number
    NextGrid.Cell[2,i].AsString := 'This is info text #' + IntToStr(i);
  end;
end;

Now I do this:

a. Click on the column header of the random number

b. Select any 3 lines with click & ctrl-click

c. Click on the column header of the index number

Expectation: The three lines selected in a) are still selected while their rows have changed because of resorting

Reality: Only one line is selected (the one with the highest row number before c)

Hope this helps to verify the problem.

Thanks in advance.

Sorry to bump this old post.

Since I don't see something like "OnBeforeSortColumn": 

Is there a good work-around for my (and MFinkle's) problem that selected rows are deselected after sorting...
