ASP.NET: Create CSV and save file on client machine

Question

Requirement: I have an ASP.NET application where a page has data displayed in gridview. This form also has a textbox which takes filepath as input, with a save button beside it. Now when the user clicks on save the csv should save it on client machine at the path the user entered.

I tried opening up a SaveAs Dialogbox using the "Content-Disposition attachment filename". But it always opens up on its default path. Is there a way to open up this SaveAs Dialog on user-specific path.

Else is there any other way of creating file on server and copying it to client machine?

Please suggest.

This cannot be done, because of security restriction. Let the user download the CSV and choose the location on his own.

Hey Michiel, so you mean only way is to open up the SaveAs Dialog and let the user save it on his own?

yes, because of security, you will have to let the user choose.

If you are trying to force the download to always give a Save As, you should set the content-type to application/octet-stream. However, it will always be up to the user to decide where that file is saved and that is as it should be for security reasons.
