Question

ASP.NET MVC application. I have a Html.DropDownList. I want to redirect to another controller when the selection is changed, and want the key of the selected dropdownlist item as a param in the URL.

How should I go about this?

Thanks

You’ll need to do this with Javascript; I would recommend using jquery. Also, put the dropdown in a form, method of get and action of the controller/action URL. Then set the click event to post the form.

So, your HTML will be something like:

<form id="myForm" action="/Controller/Action" method="get">
    <select id="mySelect">...</select>
</form>

And in jquery something like:

$('#mySelect').change(function() { $('#myForm').submit(); });

Note you can use the Html.Form() helper to create the form. Also, I’d recommend having a submit button on the form, which you can hide with javascript. Then people who have JS disabled still have a way to submit the form.
