Hi Boki,

Sorting via clicking a column header work well, however, the currently selected row does not retain selection after the sort. It is highlighted as though it is, but it's old row index is the one actually selected. Is there some way of fixing this annoying behaviour?

Best regards

Steve

Hi Boki,

I really like your components, but on occasions I need help or feedback implementing them. Unfortunately it seems like a 50/50 chance of getting a timely reply on the forum. IMO (and I apply these rules personally on my own user support forum) ALL posts should be acknowledged within a day of the original posting, and then answered ASAP after that.

Hello Steve,

I have made this behaviour by design, but I may add option that selection "follow" row after sorting.

Thanks for the reply!

IMO the current behaviour is unintuitive, .. sorting should never move the record pointer to a different data record. The row index will most likely change, but the selected record should remain selected after a sort.

Hello,

unfortunately this does also happen after moving rows. Is there any solution ?

#Thanks.

Hello Ingontrol,

First issue is fixed, but I don't understand new problem

If you move row with mouse, selected row is automatically selected. If you please can send me some more details, I will like to help.

PS. If you use MoveRow method , you may simply update SelectedRow after calling MoveRow.

Hi,

I allowed two methods for moving rows. First is the drag n' drop row moving, not a single problem. The 2nd method is MoveRow via popmenu entry. Once you moved one entry up or down, the selection moved with the item, okay - but try to select another row now, in the end you can mark all rows by moving them and try to select another row after that event.

(Image - one row moved, another one selected after that event) ..

Thanks.
Bye.

Hello Ingontrol,

Please try next example:

1) Add NextGrid on form and set aoHideSelection in AppearanceOptions to FALSE.

2) Add 2 text columns

3) Add one TButton, and on click add next code:

CODE

  NextGrid1.AddCells(['Mike','John','Lisa','Jim','Greg','Dona']);

4) Add one more button and add next code:

CODE

  NextGrid1.MoveRow(NextGrid1.SelectedRow, NextGrid1.SelectedRow + 1);
  NextGrid1.SelectedRow := NextGrid1.SelectedRow + 1;

5) Run project and select first row. If you click on second button, you may see how row is moved.

As I may see all work fine, I hope that this will help you.

If you have any more questions, please ask me.

regards

hi,

there is similar problem with selecting rows with changing rowvisible settings.
mygrid contains a full data set that will be changed according to user selection. There is another control that will trigger the updategrid() method.

CODE

// mygrid.options := [goIndicator,goSelectFullRow,...]


procedure TForm.updategrid();
var
i: Integer;
begin

with mygrid do
begin
// update row filter
for i := 0 to RowCount -1 do
begin
RowVisible[i] := AnsiSameText('Show this row in grid', CellByName[1, i].AsString);
end;

SelectedRow := 0;

// the first row will be not not selected , theres no rowindicator

I just want to have selected the first row of mygrid.

Thanks in advance,
Justus

Hello Justus,

You may try with calling method SelectFirstRow. It is just added in v4.

Please tell me if this work.

Hi again,

sorry for my dishevelment!!!!

I just found a bug in my code, so that now the rowfocus indicator is shown, but the selected row is not colored blue.

The reason might be that the selectedrow is always set to 0.
So is there a possibilty to force the coloring of the selected row?

TIA! and I will better prepared the next time I post!

Best regards,
Justus

Hello Justus,

No problem

You may set SelectionColor to desired color. Or in OnColoringCells event, add similar code:

CODE

  if csSelected in CellState then
  begin
    CellColor := clRed;
  end;
