asp.net mvc 3 - Dynamically load Partial Views

Question

How can i dynamically load a Partial View?

I mean I have this view, lets say ListProducts, there I select some dropdownlists with products, etc, and with the selected values from those I wanna fill a partial view, which would be in a div that was invisible but after onchange() event would become visible and with the data from the specific selected items.

Use jQuery's $.load() with a controller action that returns a partial view.
For example:

HTML

<script type="text/javascript">
$(document).ready(function()
{
    $("#yourselect").onchange(function()
    {
        // Home is your controller, Index is your action name
        $("#yourdiv").load("@Url.Action("Index","Home")", { 'id' : '123' }, 
                                        function (response, status, xhr)
        {
            if (status == "error")
            {
                alert("An error occurred while loading the results.");
            }
        });
    });
});
</script>

<div id="yourdiv">
</div>

Controller

public virtual ActionResult Index(string id)
{
    var myModel = GetSomeData();
    return Partial(myModel);
}

View

@model IEnumerable<YourObjects>

@if (Model == null || Model.Count() == 0)
{
    <p>No results found</p>
}
else
{
    <ul>
    @foreach (YourObjects myobject in Model)
    {
        <li>@myObject.Name</li>
    }
    </ul>
}
