  2. upload begins when open clicked in dialog
  3. the file type in dialog should restricted csv, txt , files
  4. the initial directory should able set depending on user preferences

i've used jquery first 2 requirements (shown below) not if best way or how accomplish last two.

view:

@using (html.beginform("import", "date", formmethod.post, new { enctype = "multipart/form-data", id="fileupload" })) {     <input type="file" name="file" id="file" style="display: none;" />     <input type="button" id="import" value="import" /> }  <script type="text/javascript">     $(document).ready(function () {          $('#file').change(function () {             $('#fileupload').submit();         });          $('#import').click(function () {             $('#file').trigger('click');         });      }); </script>

controller:

[httppost] public actionresult import(httppostedfilebase file) {       // stuff }
