How to call action method without view

I want to call a action method in controller. but the actonmethod has no view.

I have this:

 <div class="col-lg-6 col-md-8 col-sm-10 ">       
        <a href="@Url.Action("GeneratePDFFFromHtml", "Product")" class="btn btn-primary enabled"><i class="fa fa-fw fa-check"></i> @Resources.Action.Navigation.GeneratePDF </a>      
    </div>

and this is my action method:

[HttpPost]    
public ActionResult GeneratePDFFFromHtml(EditProductModel model, string data)
{           
    SubmittedForm sf = new SubmittedForm();
    string schema = requestSchema;
    customer_DbConnection db = new customer_DbConnection();
    RenderFormController renderController = new RenderFormController();
    renderController.GeneratePdf(data, db,sf);
    //return RedirectToAction(model.DesignId, "Prdocut/Edit");
    return Content("It works");           
}

Thank you Andy Korneyev!!! Your sample code helped me solve something I have been struggling with all day. I used your code (and modified it slightly) to go back after running a code block function without a refresh/view.

return Content("<script type='text/javascript'>window.history.back();</script>");

I know this is really old but hopefully you see this.

Easier way is to use routing, route attribute with your controller as below.

In your controller simply decide the needed route and add it. I've used ImportExport 

[Area("Exporting")]
[Route("api/ImportExport")]
public class ImportExportController : Controller
{
    ............

    [Route("GeneratePDF")]
        [HttpPost]    
            public void GeneratePDFFFromHtml(string designId, string strData)
            {           
                SubmittedForm sf = new SubmittedForm();
                string schema = requestSchema;
                customer_DbConnection db = new customer_DbConnection();
                RenderFormController renderController = new RenderFormController();
                renderController.GeneratePdf(strData, db, sf);
                //return RedirectToAction(model.DesignId, "Prdocut/Edit");       
            }

    .......

And in your cshtml page simply call this path as below 

<form enctype="multipart/form-data" method="post" action="~/api/ImportExport/GeneratePDF" id="frmGenerate" novalidate="novalidate" class="form-horizontal">
.....

If you want do to some work based off a button/link, why not just use an ajax call?

For example:

<div class="col-lg-6 col-md-8 col-sm-10 ">       
    <button onclick=GeneratePdf('@Model.DesignId', <string data>) class="btn btn-primary enabled"><i class="fa fa-fw fa-check"></i> @Resources.Action.Navigation.GeneratePDF </button>      
</div>

And in your .cshtml, I would recommend having a Script section at the bottom of the file:

@section Scripts{
    <script type="text/javascript">
        //modify as needed to make it pass in what you need.
        function GeneratePdf(designId, stringData) {
            $.ajax({
            url: "@Url.Action("GeneratePDFFFromHtml","Product")",
            data: { designId: designId, strData: stringData },
            cache: false,
            contentType: false,
            processData: false,
            type: "POST",
            success: function (data) {
                //TODO: Add whatever if you want to pass a notification back
            },
            error: function(error) {
                //TODO: Add some code here for error handling or notifications
            }
        }
    </script>
}

Then, in your controller, you can have your function return void. NOTE: I am not really sure if you even need to pass in the DesignId but you have it in there so I will keep it there. You will most-likely need to edit this method some more to make it work properly but hopefully this will get you going.

[HttpPost]    
public void GeneratePDFFFromHtml(string designId, string strData)
{           
    SubmittedForm sf = new SubmittedForm();
    string schema = requestSchema;
    customer_DbConnection db = new customer_DbConnection();
    RenderFormController renderController = new RenderFormController();
    renderController.GeneratePdf(strData, db, sf);
    //return RedirectToAction(model.DesignId, "Prdocut/Edit");       
}

Also, this will be async so you may want some notification to the user that some action is being done like a spinner.

Try with System.Web.Mvc.EmptyResult or redirecting to same page with System.Web.Mvc.RedirectResult.
