DBComboBox RemoteQuery

[dkeene]

Hello

I am trying to use RemoteQuery on a DBComboBox to build a query based on the value of the DBComboBox's textbox as a user types some keys.

Instead of using the event: DBComboBox.OnChange(Sender: TObject) to process the request, i will set property RemoteQuery to True, and  will now use

uniDBComboBoxRemoteQuery(const QueryString: string; Result: TStrings); to grab the value of QueryString and build an SQL statement.

However, unlike OnChange(Sender: TObject), now I don't have any knowledge of which control is triggering this event. Is there any way of grabbing the sender of this event and why is it not included in as something like

DBComboBoRemoteQuery(Sender: TObject; const QueryString: string; Result: TStrings);

Please help

Thanks

Perhaps one could use the form's ActiveControl property, but I try during the 

procedure TForm.DBComboboxRemoteQuery(const QueryString: string; result: TStrings);

begin

   if self.ActiveControl is UniDBCombobox then
      begin
         ....do something

      end;

 

end

 

Despite the control that triggers this event, Self.ActiveControl is nil...

Any thoughts?>

Any ideas here?

I need that solution too. 😕

To be precise, what exactly is the issue?

[PS1]

Issue was to have sender(DBComboBox) so you just can write one function in which you can use (sender as TUniDBComboBox)... .

i found solution already, there is second event called: 

RemoteQueryEx(Sender: TComponent;  const QueryString: string; Result: TStrings);

 

where the sender is given.
