After creating & populating a row, I code the following

CODE

NextGrid1.EditCell(1,i,'New Item');

The cell is in edit mode.

But if I clear the cell, the AfterEdit event never occurs !

How can I control the cell content in this case ?

I try next the EditAccept event.... but NextGrid1.Cell[ACol,ARow].AsString is always an empty string.

Hello qi,

Can you please tell me what do you think with "clear the cell":

1) Enter in edit-state and clear all text with Delete or Backspace and then finish editing
2) Press ESC key and exit from edit state.

When Esc key is pressed, there is no call for OnAfterEdit event.

Best regards

Hi Boki

It's the #1.

Cursor is at the end of the string 'New Item'. Then, backspace or select all+del, then clic outside the cell.

Regards.

May be...

Can you tell me which events occur when I click outside the cell I'm currently editing ?

Hello Qi,

There is no event when editing is canceled. If edit is completed (new value is added/changed), OnAfterEdit occur.

I agree that new event when editing is finished (canceled or accepted), need to be added. I will add it as soon as possible.

I think that Grid must call "OnBeforeEdit" when Grid open any inplace editor
and call "OnAfterEdit" when Grid close inplace editor.

Other events must be fired in specific cases. It is logical.


With best wishes.

Hello Shaman,

I agree that this is a problem. Because OnAfterEdit is already reserved for successfully editing (maybe many users are using it), I will like to add new edit when editing is finished no matter how.

I only don't know which will be good name be for this event

May be "OnOpenEditor" and "OnCloseEditor"?

The most impotant task - find out when Grid in edit mode.

Hello,

Maybe OnEditExit? I will most probably add this kind of event in next 1-2 days.

Hello,

I have added OnEditExit event. This event have no parameters.

This event occur when editing is over, not matther if is accepted or not. This event is last event in editing events array.

Thanks. Very suitable event.

Hello Shaman,

If you already installed v4.2.1, please change next procedure:

CODE

procedure TNxCustomGridControl.EndEditing;
begin
    if (Assigned(InplaceEdit)) then
    begin
    ShowWindow(InplaceEdit.Handle, SW_HIDE);
    if gtEdit in GridState then RefreshCell(FEditingCell.X, FEditingCell.Y);
    if gtInput in GridState then RefreshColumn(Columns[FInputingColumn], gaInput);
    TGraphicsProvider.SetClipingRect(Canvas, ClientRect);
    end;
  if gtEdit in FGridState then
  begin
    DoEditExit; { event }
  end;
    FGridState := FGridState - [gtEdit, gtInput];
  FEditingCell := Point(-1, -1);
  if FInputingColumn <> -1 then
  begin
    Columns[FInputingColumn].Input := False;
    FInputingColumn := -1;
  end;
  InplaceEdit := nil; { important }
end;

in NxCustomGridControl.pas file (Sources\Next Grid).

This will cause that this event is called ONLY after grid exit from edit cell state (not from Input state too).

I hope that this is correct behaviour.

Best regards
