Insertion in DBGrid.

[M477H13U]

Hello UniGUI users !!

 

I would like to know if it is possible to change the behavior of escape shortCut while inserting a new row in a grid.

 

Actually, the behavior is as fallow:

• you're editing the newly inserted row.
• Press escape button
• the whole line is deleted

We would like this behavior:

• you're editing the newly inserted row.
• Press escape button once
• current cell's value is reset
• Press escape button a second time.
• The whole line is deleted.

How could we achieve something like that ?

 

Regards,

Can you try this solution as a "workaround" ?!

 

1. UniDBGrid1 -> ClientEvents -> ExtEvents ->

function canceledit(editor, context, eOpts)
{
    return false
}

2. UniDBGrid1 -> ClientEvents -> ExtEvents ->

function keydown(e, t, eOpts)
{
    if (e.keyCode == 27) {
        ajaxRequest(this.grid, '_cancel', []);        
    };
}

3. UniDBGrid1 -> OnAjaxEvent

procedure TMainForm.UniDBGrid1AjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = '_cancel' then
    with (Sender as TUniDBGrid).DataSource.DataSet do
      if Active and (State in [dsInsert]) then
        Cancel;

end;
