ถ้าต้องการให้ลาก button ใน gridview แล้วให้ drag & drop โดยใช้ JQuery

function griddragdrop() {
  /*Drag & Drop*/
  $(function () {
    $("[id*='ugv'] tbody").sortable({
      items: 'td.class-name', // Only allow dragging and dropping within td elements
      cursor: 'pointer',
      axis: 'y',
      dropOnEmpty: false,
      start: function (e, ui) {
        ui.item.addClass("selected");
      },
      stop: function (e, ui) {
        ui.item.removeClass("selected");
      },
      receive: function (e, ui) {
        // Get the target and source rows
        var targetRow = $(this).closest('tr');
        var sourceRow = ui.sender.closest('tr');

        // Move the source row before or after the target row, depending on the drop position
        if (ui.position.top > ui.originalPosition.top) {
          // Drop position is below the source row, so insert after the target row
          targetRow.after(sourceRow);
        } else {
          // Drop position is above the source row, so insert before the target row
          targetRow.before(sourceRow);
        }

        // Reset the table sorting
        $(this).sortable("refresh");
      }
    });
  });
}
