How to implement file download with AJAX and MVC

Question

I would like to provide a file download operation by using the jQuery AJAX call with some params under MVC

Example

(javascript)
function DoDownload(start         


        

Answer 1

Using the ActionLink helper, you can pass multiple params to your controller:

HtmlHelper.ActionLink(
    string linkText, 
    string actionName, 
    string controllerName, 
    object routeValues, 
    object htmlAttributes
)

So in your case:

@Html.ActionLink("Download file", "GetFile", "MyController", new { startDate = "##" }, new { id="mydownloadlink" })

Using jQuery you can change the value of the startDate in the link with the content of your date picker or textbox.

$("#mydownloadlink").attr("href").replace("##", $("#yourdatetexbox").val);

Then, in your controller, just use one of the other answers here, about FileResult.

Hope this help you...
