Question

Hi I have this code in my view..

<%=Html.DropDownList("ProductTemplate",new SelectList(Model.ProductTemplate,"Value","Text"))%>

I know if this dropdownlist box is in between BeginForm submit I can able to access the value in Controller using collection["ProductTemplate"];

if it is not in my beginForm still I can able to access this selected value in controller?

thanks

You could use AJAX to send the value of the currently selected element to a controller action. This is pretty trivial with jQuery:

$.post('/home/foo', { productTemplate: $('#ProductTemplate').val() }, function(data) {
    alert(data.success);
});

And to access the selected value in your controller action simply use a parameter:

[HttpPost]
public ActionResult Foo(string productTemplate)
{
    // TODO: do something with the selected productTemplate
    return Json(new { success = true });
}
