How do I create xml file browse then display data in gridview

Asked by: yvsupport

Hi

Part 1) I need to create a page that allows a user to browse for an xml file on the client. If possible the open file dialog must have a .xml filter
Part 2) When the import button is clicked the data in the xml file is then displayed in a gridview.
Solution required in ASP.NET2.0 and C#
Thanks in advance.

For Part (1)

private string SelectXMLFile ( string initialDirectory )
{ 
   OpenFileDialog dialog = new OpenFileDialog(); 
   dialog.Filter = 
      "XML files (*.xml)|*.xml"; 
   dialog.InitialDirectory = initialDirectory; 
   dialog.Title = "Select a text file"; 
   return ( dialog.ShowDialog() == DialogResult.OK )
      ? dialog.FileName : null;

Thanks for your reply Suraj, however surely I can't use OpenFileDialog as this is for Windows Forms. Correct me if I'm wrong but I thought you cannot use modal dialogs in a web app.

 

by: surajgupthaPosted on 2007-12-11 at 10:39:56ID: 20451448

arghh am sorry.. made too many assumptions...
If you are not opposed to using AJAX, you can try the modalpopup extender in AJAX. its cool

 

by: yvsupportPosted on 2007-12-13 at 02:21:36ID: 20463397

The only reason why I wanted to use OpenFileDialog was for file extension filtering but
I'll just stick to the html file upload control and validate the file extension instead.
I don't have time to learn AJAX atm.

But thanks for your comments anyway.

 

by: yvsupportPosted on 2007-12-13 at 02:23:46ID: 20463409

To correct my last comment, I meant I wanted something similar to the OpenFileDialog but for a web app.

Some browsers support the ability to restrict the kinds of files (that can be attached to the contents of a form) using an ACCEPT attribute. The value of that attribute is a comma-separated list of MIME content types. For example, ACCEPT="image/*" would restrict files to images. Notice that the ACCEPT attribute is not defined in HTML 3.2, although it is defined in RFC 1867 to which the HTML 3.2 Reference Specification refers in this context for further information.

You can use the <input type="file" name="somename" accept="image/*">

I object. I didn't accept any of surajgupta's solutions. See comment ID 20463397.

Sorry, to make myself clearer, I object to the points being awarded. The question can still be closed.

yvsupport, I have made a suggestion here and there is no response from you indicating it didnt work or if it worked. Because of your inactivity this question is being closed accepting my solution by default. If you have a question open, i would suggest responding to the suggestions made and not just close it without any reason.
