Show your loading image before ajax request, and hide on success or error handlers.

add <div class="loading">Loading...</div> to your markup

$('.loading').fadeIn(50);
$.ajax({
    url: '@Url.Action("CheckLogin","Home")',
    data: postdata,
    success: function (msg) {
        $('#Result').html(msg);
        $('.loading').fadeOut(50);
    },
    error: function (data) {
        $('#Result').html(msg);
        $('.loading').fadeOut(50);
    }
});

Take a look at the ajaxStart() and ajaxStop() event handlers in jQuery. You could use these to show and hide a layer with a gif-animation.

use beforSend and complete attributes.

$.ajax({
        url: '@Url.Action("CheckLogin","Home")',
        data: postdata,
        success: function (msg) {
            $('#Result').html(msg);
        },
        error: function (data) {
            $('#Result').html(msg);
        },
        beforeSend: function() {
            $("body").append("<div class=\"ajaxLoader\" id=\"ajaxLoader"\"><div class=\"ajaxAnimation\"></div></div>");
            $("#ajaxLoader").hide();
            $("#ajaxLoader").fadeIn('fast');
        },
        complete: function() {
        $("#ajaxLoader").remove();
    }

   });

And specify animation with css

.ajaxAnimation {
    background-image: url('images/ajax-loader.gif');
    background-repeat: no-repeat;
    background-position: center center;
}
