launch download from dbgrid

[delagoutte]

hello,

i have a unidbgrid linked to a datasource that displayed a list of filename.

Actually if i'm using the event onDblClick and i have this code :

procedure TUniForm.GridDCEDblClick(Sender: TObject);
var urlFile : string;
begin

    urlfile := UniMainModule.GetUrlFileServer+'/?'+UniMainModule.getParameterCurrentFile;
    UniSession.AddJS('window.open('''+urlfile +''',''_blank'');');
  end;
end;

urlfile is a url that is on another webserver than unigui webserver.

SO when i double click on cell that must launch a file download.

 

WIth this methode i'm blocked by webbrowser because it think it is a popup. If i unblock popup security the file download is launched.

It's working but i think there must be a better solution without unblock popup security.

 

how would you do? hope I was clear enough

Check download demos. Maybe something will help you.

the download demos work with stream or file that are on the unigui web server but in my case the file are on other server.

issue :

i had a TUniURLFrame with property visible := false

 

and

ir replace

UniSession.AddJS('window.open('''+urlfile +''',''_blank'');');

with

UniURLFrame1.URL:= urlfile ;

Create a new calculated field, put link to the file there in OnCalcFields

DataSet.FieldByName('download').AsString := '<a href="' + UniMainModule.GetUrlFileServer+'/?'+UniMainModule.getParameterCurrentFile + '">Download</a>'

User will see an ordinary link in this cell which he can click.
