display saveas file dialog box

the type of file should automatically displayed in saveas dialog box.eg if type of file image in saveas dialog box .jpg should automatically displayed. have attached image of output here not clear concept.please help in advance

the savefiledialog windows forms control, doesn't work on website.

a browser display "what want file" dialog whenever server sends stream can't handle default - unfortunately, browsers can handle text streams, display them user.

but should going:

// clear response buffer: response.clear(); // set output plain text: response.contenttype = "application/octet-stream"; // send contents of textbox output stream: response.write(txtnewfile.text); // end response don't else sent (page piece of furniture etc): response.end();
