In my current project I need to load the user control dynamically without post back. After some googling found couple of posts which converts the partial view as string. The issue here is it doesn’t support viewcontext, in my case i have custom view engine which implements localization. Earlier i have gone through this useful cheat sheet. Below is the simple implementation which works with custom view engine and view context.

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult LoadTopDestinations()
{
    return PartialView("TopDestinations");
}

And this is how i call the controller from the javascript using jquery post.

function TopDestinationClick() {
    proxy.invoke("/Home/LoadTopDestinations", "", TopDestinationCallback, OnError);

}

Thanks to Rick Strahl for the easy service proxy for jquery post.

function serviceProxy(serviceUrl)
{
    var _I = this;
    this.serviceUrl = serviceUrl;
    
    // *** Call a wrapped object
    this.invoke = function(method, data, callback, error) {
        // *** The service endpoint URL        
        var url = _I.serviceUrl + method;
        //alert(url);
        $.ajax({
            url: url,
            data: '',
            type: "GET",
            contentType: "html",
            timeout: 10000,
            success: callback,
            error: OnError
        });
    }
}

// *** Create a static instance
var serviceUrl = "";
var proxy = new serviceProxy(serviceUrl);

And the callback event, just use jquery.html() method to load the partial view result.
