Handling 2 buttons submit Actions in a single View/Form - ASP.NET MVC 2 RTM

Question

I have a View in which the user is able to upload a file to the server.

In this view I also have 2 buttons: one to Upload a file and other to Download the last file

Answer 1

maybe this will give u the idea:

view:

<form enctype="multipart/form-data" method="post" action="/Media/Upload/Photo">
    <input type="file" name="file" id="file" /> 
    <input type="submit"  name= "submitImport" value="Upload" />
    <input type="submit" name = "submitExport"  value="Download" />
</form>

controller:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Action (FormCollection formCollection)
        {
            if (formCollection["submitImport"] != null)
            {
                return Import(formCollection);
            }
             if (formCollection["submitExport"] != null)
            {
                return Export(formCollection);
            }
        }

the Export and Import are the appropriateactions

Answer 2

To generate a POST request for the upload, use the File Input form element and just post back to the server ala normal.

Have a look at this blog post from Scott Hanselman. http://www.hanselman.com/blog/ABackToBasicsCaseStudyImplementingHTTPFileUploadWithASPNETMVCIncludingTestsAndMocks.aspx

Answer 3

You have to use a "multipart/form-data" form, and submit the form. No ActionLink.

<form enctype="multipart/form-data" method="post" action="/Media/Upload/Photo">
    <input type="file" name="file" id="file" /> 
    <input type="submit" value="Upload" />
</form>
