Q:

after Jquery onDrop, how to Ajax GET and append ActionResult of PartialView to Div

In a page, I have 
<ul id="myPicsMakeAlbum" > 
    <li id="pic1" data-index-number="picture1"></li>
    <li id="pic2" data-index-number="picture2"></li>
    <li id="pics3" data-index-number="picture3"></li>
</ul> 
list of thumbnails/imgs and  where user can drag and drop those thumbnails of documents.
Following the OnDrop() event: How do I trigger/male an Ajax call to the ASP MVC Action Method, with the id of the list item.
Then append the return ActionResult from the partialview/View as a nest div inside the container.
<div id="container"></div> 

    $("#containere").droppable({ 
        accept: "#container",
        drop: function( event, ui ) {
            //how to make the ajax call with item id?
        } 
});

How do I wrap this inside an onDrop Call with a unique Id of the item
$.ajax({
    type: "GET",
    url: "/Home/GetMyPartialView/",
    data: ThumNailId,                //** how do I wire this up to the dragDrop**
    success: function (myresult) {     
        if (myresult.Status === 300) { //300 is an arbitrary value I just made up right now
            showPopup("You do not have access to that.");
        }

        $("#Container").html(myresult.ViewString); //the HTML I returned from the controller
    },
    error: function (errorData) { onError(errorData); }
});

Should I use Html.Partial or Partial View here?

A:

The ui parameter contains the information about the element that was dragged, so you can use
$("#containere").droppable({ 
    accept: "#container",
    drop: function( event, ui ) {
        var id = ui.draggable.data('index-number'); // returns 'picture1' if the 1st li element is dragged/dropped
        // or var id = ui.draggable.attr('id'); if you want the 'pic1' value
        $.ajax({
            type: "GET",
            url: '@Url.Action("GetMyPartialView", "Home")', // don't hard code url's
            data: { ThumNailId: id },
            ....
        });     
    } 
});

Note, this assumes your method is signature is
public ActionResult GetMyPartialView(string ThumNailId)
