How do you submit a dropdownlist in asp.net mvc

Question

<% using (Html.BeginForm() { %>

  <%=Html.DropDownList("TopItemsList", ViewData["ListData"], new { onchange="[???]" })%>

<% } %>

In the above example, what value should you set onchange to? Or, how do you get the correct form?

Is there any difference with Ajax.BeginFrom?

try this:

<%=Html.DropDownList("TopItemsList", ViewData["ListData"], new { onchange="this.form.submit();" })%>

Every form element in the has a "form" property that is pointed to the form that contains this element.

Yes, using "Html." and "Ajax." has a difference. Ajax. means that partial page update will be used and the whole page will not be reloaded.

Just to correct the statement, <%=Html.DropDownList("TopItemsList", ViewData["ListData"], new { @onchange="this.form.submit();" })%> note the @ symbol.

If you have multiple dropdowns or textboxes you need to do this too, I created a CSS class and added this JS. $(".ajaxForcePost").change(function () { this.form.submit(); });

Why are you mixing your html with javascript??

Delete the onchange attribute and add some JQuery:

$("#TopItemsList").change(function () {

    $("input[type=submit]").click();

});

Will cause issues if you have more than one submit input.
