Question

How to call Post method on DropDownList selection in ASP.Net MVC?

Answer 1

A:

Hey,

Are you using JQuery? You could use $.post to post your data in the onchange event... I think in the web forms way it was using a _doPostBack call in the onchange event if you set AutoPostBack to true... not 100% sure about that.

Thanks Brian.I am using Javascript to handle onchange event. How can i do so there?

try doing _doPostBack('<Select element name>', '<command>') and see if that works. That is a part of the MS Ajax framework and so you need to reference that.

+1 A:

You can do this using JQuery

 <select id="idXYZ" name="XYZ" onchange="SetUnit(this.value)">
 <%=  ViewData["YourValue"]%>
</select>

Now use JQuery

<script type="text/javascript">
function SetUnit(unit) {
        $.post("/Admin/YourMethod?itemid=" + unit.toString(), function(data) {
            var data = eval('(' + data + ')');
            $("#idunit").html(data.Value);
        });
    }

</script>

If you are not using Jquery then use Ajax post method directly//POST http.open("POST", url, true);

Thanks Pankaj,but instead of <select>, i have used <%=Html.DropDownList...>.Then i did the same as you have said above. But unfortunately it's not working for me.

@@Kapil you are not using JQuey that's why your $.post is not working.Please use ajax post. see this article to use ajax posthttp://viralpatel.net/blogs/2008/12/ajax-post-method-example-using-javascript-jquery.html
