Saving form when there is autopostback

Question

I'm very new to MVC3.In my view page I've a dropdown list and some fields data in the following way.

View:-

 //dropdownlist data
 @Html.DropDownList("Category", new SelectList(categoriesList, selectedCategory), "Select One", new { onchange = "this.form.submit();" })


  @Html.EditorFor(model => model.Name)
  @Html.ValidationMessageFor(model => model.Name)


  <input type="submit" name="Create" value="Create" />

Here both the submit button and dropdown control submitting the form I'm wondering how the controller can identify the call is happened via submit button but not from the dropdownlist. your help is really appreciate.

Please clarify what do you exactly want to do. – Yair Nevet Jul 19 '12 at 15:29 — Yair Nevet, Jul 19 '12 at 15:29

There is no AutoPostback concept in ASP.NET MVC. Autopostback is a feature of WebForms.

ASP.NET MVC uses normal form posting. so your controller action will get the values when the form is posted by clicking on the submit button.

you can always write some javascript code to listen to the change event of the dropdown and so a form submit. So in your case, It is the onchange event calling the form.submit method

I got the solution. Just name the buttons and pass the button name as String to the controller method and verify with the vale by doin the following. – Trinadh Jul 19 '12 at 15:52
