Drag and Drop GridView not woking when Paging enabled

In your drag drop code you just ignore first child but to ignore paging line i want to ignore last child 

<script type = "text/javascript">
         $(function () {
             $("#cs100_placeholder1_GridView1").sortable({
                 items: 'tr:not(tr:first-child)',
                 cursor: 'crosshair',
                 connectWith: '#cs100_placeholder1_GridView2',
                 axis: 'y',
                 dropOnEmpty: true,
                 receive: function (e, ui) {
                     $(this).find("tbody").append(ui.item);
                 }
             });
         });
 
     </script>

Ask new question for this as this is different from what was asked in actual question

i aked this question here because i was thinking if we ignore first and last child (footer where pages index are display)are ignored then may be its possible to drop row in that grid view where page index are display,,please try to give possible solution if we ignore headers of grid then is there any way to ignore footer  of grid view

The logic of drag and drop is for tables hence as said before it will not work for gridview with paging.

You will have to remove paging if you need to use this
