How can I determine when the Exporter has completed

[Tinygoldwing]

User clicks to export grid they are presented with a list of column title from the grid.  They can check or uncheck the ones they want to export.  They choose them and I set the remainder of the fields visible to false.  So far so good.  Works great.

However I can't determine when the exporter has completed to reset the columns visible property back.  I tried a bunch of ways to including setting a timer but that's a fixed value and no one would want to wait seconds to do this even though it finished seconds earlier.

Thank you for the help.

Hello,

Solution for now (with some practical benefit): 

1. Form OnCreate event ->

procedure TMainForm.UniFormCreate(Sender: TObject);
begin
  with UniDBGrid1.JSInterface do
  begin
    JSAddListener('beforedocumentsave', 'function(sender, params){ajaxRequest(sender, "_beforedocumentsave", {}, false)}');
    JSAddListener('documentsave', 'function(sender, params){ajaxRequest(sender, "_documentsave", {})}');
  end;
end;

2. UniDBGrid OnAjaxEvent ->

procedure TMainForm.UniDBGrid1AjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = '_beforedocumentsave' then
  begin
    UniButton1.Enabled := False;
  end
  else if EventName = '_documentsave' then
  begin
    UniButton1.Enabled := True;
  end;

end;
