How to Generate a .CSV file on the client side and save it as download?

Hi,

i try to allow the client to download the data he manipulated on the client side.
But i have no idea how i can pop up a "save export" dialog.

Can someone please explain how to do that?

The basic idea is, to use the data he entered, put a long string together and allow him to save this as download.
(The data is not available on the server)

Thanks

As far as I know this won't be possible on the client side. The browser opens the Save dialog when it receives a response from the server with Content-Disposition set to attachment. I don't think this can be achieved using GWT (which internally uses javascript and javascript can't do this)...
