asp.net mvc - KendoUI Upload Control not posting correctly -

using vs'12 kendoui - c# asp.net mvc ef code first internet application template

• i have gotten kendo ddl ( dropdownlist ) work,

  i working on post actionresult when found that

  if (modelstate.isvalid) false when click on kendoui upload button ( 1 bound in control)

• if click on regular submitt button <input type="submit" value="upload" id="do" class="k-button"/> modelstate.isvalid true, none of "upload selected files" in [httppost] actionresult

my question simple , how post both of them controller @ once?

here little example of code ( 2 buttons )

<div>          <p>         <input type="submit" value="upload" id="do" class="k-button"/>     </p> </div>  @(html.kendo().upload()         .name("attachments")         .async(async => async             .save("index", "imageupload")             .autoupload(false)         ) ) 

you configured upload control upload files asynchronously; therefore, doesn't post with form. if want both form data , files post @ same time same controller, need configure upload control synchronous, not async, , need add enctype="multipart/form-data" <form/> tag. in mvc controller, make sure 1 of parameters ienumerable<httppostedfilebase> attachments along form data model parameter(s).
