Simple, select a row in grid ...

[jorgo]

Hi,
we have a filled grid.
column = 0 has checkboxes

Now I check the checkboxes in rows 1,3,5 -> Ok

Code: Select all

procedure TForm1.IWCGJQButton1JQButtonOptionsClick(Sender: TObject; AParams: TStringList);
begin
   IWCGJQGrid2.JQGridProviderCells.Rows.CellValue[0, 1] := 1;
   IWCGJQGrid2.JQGridProviderCells.Rows.CellValue[0, 3] := 1;
   IWCGJQGrid2.JQGridProviderCells.Rows.CellValue[0, 5] := 1;
   IWCGJQGrid2.JQGridOptions.ReloadGrid;
end;

How can I select row = 3 (like clicking on it)?

Kind regards

Hi,

the button is not on the grid.
It's a button direct on the from.

I tested following, but it didn't select row = 3:

tmpRowId := IWCGJQGrid2.RowId[3];
IWCGJQGrid2.JQGridOptions.SetSelection(tmpRowId, True);

Hi jorgo,

This topic will help you: viewtopic.php?f=34&t=1744

Hi,

IWCGJQGrid2.JQGridOptions.ReloadGrid;
IWCGJQGrid2.JQGridOptions.SetSelection(3, True);

Call of both methods in one event doesn't work.
The selection is shown for milliseconds before the grid is repainted without a selection.

So I need an event after "ReloadGrid" is performed.
I took onLoadComplete:

Code: Select all

procedure TForm1.IWCGJQGrid2JQGridOptionsLoadComplete(Sender: TObject; AParams: TStringList);
begin
   try
      IWCGJQGrid2.JQGridOptions.SetSelection(3, True);
   except
   end;
end;

Hi Jorgo

You did the right thing

My colleague didnt understand you well, he thought you want to track the selected row, not to select a specific row,

[jorgo]

Hi,

if I combine
IWCGJQGrid2.JQGridOptions.SetSelection(x, True);

with
IWCGJQGrid2.JQGridOptions.ScrollRows := True;

grid is scrolled to the last selected row.

[Jorge Sousa]

remember that the first parameter of setSelection is the rowid not the rownumber, can you send us a test case, please? t.i.a.

Ups,

was this the wrong smilie?
It works as I want it.

The bigger problem is to update visual components during a long runing calculation.
Now I use timers and run it part for part but it's ugly source code.

Kind regards
