I am looking for asp.net mvc dropdown list which can adds records if scrollbar is scrolled. I am completely beginner to this area. Could some one guide me on how to implement th
Jquery Code
Below is the Code for using ajax call to controller and get records then bind into to dropdown
var mySelect = $('#mySelect');
var sIndex = 11, offSet = 10, isPreviousEventComplete = true, isDataAvailable = true;
mySelect.scroll(function (e) {
if($(this).scrollTop() + $(this).innerHeight()>=$(this)[0].scrollHeight)
{
var scrollto=$(this).scrollTop();
if (isPreviousEventComplete && isDataAvailable) {
isPreviousEventComplete = false;
$(".LoaderImage").css("display", "block");
$.ajax({
type: "GET",
url: 'Your url',
success: function (result) {
$.each(result, function(val, text) {
mySelect.append(
$('<option></option>').val(val).html(text)
);
});
mySelect.scrollTop( scrollto );
isPreviousEventComplete = true;
if (result == '') //When data is not available
isDataAvailable = false;
$(".LoaderImage").css("display", "none");
},
error: function (error) {
alert(error);
}
});
}
}
});

You can also try this JQuery Select which will support infinite scroll of results.
