    I want to drag and drop from a RadListBox To another RadListBox in a table ?

    and persist this server side but it not works :

    My .cs :

    protected void Page_Load(object sender, EventArgs e)
                // Total number of rows.
                int rowCnt = 4;
                // Current row count.
                int rowCtr;
                // Total number of cells per row (columns).
                int cellCtr;
                // Current cell counter
                int cellCnt = 7;

               // rowCnt = int.Parse(TextBox1.Text);
               // cellCnt = int.Parse(TextBox2.Text);

                for (rowCtr = 1; rowCtr <= rowCnt; rowCtr++)
                    // Create new row and add it to the table.

                    HtmlTableRow tRow = new HtmlTableRow();
                    for (cellCtr = 1; cellCtr <= cellCnt; cellCtr++)
                        // Create a new cell and add it to the row.
                        HtmlTableCell tCell = new HtmlTableCell();
                       // tCell.Text = "Row " + rowCtr + ", Cell " + cellCtr;
                        RadListBox rr = new RadListBox();
                        rr.ItemTemplate = new RadListBoxTemplate();
                        rr.SelectionMode = ListBoxSelectionMode.Multiple;
                        rr.AllowReorder =true;
                        rr.AutoPostBackOnReorder =true;
                        rr.EnableDragAndDrop =true;
                        List<int> i = new List<int>();
                        rr.DataSource = i;
            class RadListBoxTemplate : ITemplate
                public void InstantiateIn(Control container)
                    Label id = new Label();
                    id.ID = "idLabel";
                    id.CssClass = "idClass";
                    id.DataBinding += new EventHandler(id_DataBinding);
                    Label name = new Label();
                    name.ID = "nameLabel";
                    name.CssClass = "list";
                    name.DataBinding += new EventHandler(name_DataBinding);
                    HyperLink details = new HyperLink();
                    details.ID = "details";
                    details.CssClass = "list";
                    details.Text = "Details";
                    details.DataBinding += new EventHandler(details_DataBinding);
                private void id_DataBinding(object sender, EventArgs e)
                    //Label target = (Label)sender;
                    //RadListBoxItem item = (RadListBoxItem)target.BindingContainer;
                    //string id = Convert.ToString((int)DataBinder.Eval(item.DataItem, "ID"));
                    //target.Text = id;
                private void name_DataBinding(object sender, EventArgs e)
                    //Label target = (Label)sender;
                    //RadListBoxItem item = (RadListBoxItem)target.BindingContainer;
                    //string name = (string)DataBinder.Eval(item.DataItem, "Name");
                    //target.Text = name;
                private void details_DataBinding(object sender, EventArgs e)
                    //HyperLink target = (HyperLink)sender;
                    //RadListBoxItem item = (RadListBoxItem)target.BindingContainer;
                    //string id = Convert.ToString((int)DataBinder.Eval(item.DataItem, "ID"));
                    //target.NavigateUrl = "Details.aspx?ID=" + id;
    My .aspx like this :

      <telerik:RadScriptManager runat="server" ID="RadScriptManager1" />
        <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" CssClass="example-panel">
