I am working for the first time with the radgrid drag and drop feature; I believe I do have it working properly as I can view the row count growing as I drop new items. However, my grid does not reflect this. My code is below. PLEASE HELP!
Imports System.Data Partial Class Sales_SalesPresentationGenerator Inherits System.Web.UI.Page Dim ds As New DataSet Dim TitleName As DataColumn = New DataColumn("Title", Type.GetType("System.String")) Dim TitleID As DataColumn = New DataColumn("TitleID", Type.GetType("System.Int32")) Dim Territory As DataColumn = New DataColumn("Territory", Type.GetType("System.String")) Dim TerritoryID As DataColumn = New DataColumn("TerritoryID", Type.GetType("System.Int32")) Dim Medium As DataColumn = New DataColumn("Medium", Type.GetType("System.String")) Dim MediumID As DataColumn = New DataColumn("MediumID", Type.GetType("System.Int32")) Private Property dt As DataTable Get Return ViewState("dt") End Get Set(value As DataTable) ViewState("dt") = value End Set End Property Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load If Not IsPostBack Then dt = New DataTable() dt.Columns.Add(TitleID) dt.Columns.Add(TitleName) dt.Columns.Add(TerritoryID) dt.Columns.Add(Territory) dt.Columns.Add(MediumID) dt.Columns.Add(Medium) SelectedGrid.DataSource = dt SelectedGrid.DataBind() End If End Sub 'Add to selected Protected Sub TitlesGrid_RowDrop(sender As Object, e As Telerik.Web.UI.GridDragDropEventArgs) Handles TitlesGrid.RowDrop 'e.DraggedItems.Count For Each r In e.DraggedItems Dim temp As DataRow temp = dt.NewRow() temp.Item("TitleID") = CType(CType(r.Item("TitleID"), TableCell).Text, Integer) temp.Item("Title") = CType(r.Item("Title"), TableCell).Text temp.Item("Medium") = CType(r.Item("Medium"), TableCell).Text temp.Item("MediumID") = CType(CType(r.Item("MediumID"), TableCell).Text, Integer) temp.Item("Territory") = CType(r.Item("Territory"), TableCell).Text temp.Item("TerritoryID") = CType(CType(r.Item("TerritoryID"), TableCell).Text, Integer) dt.Rows.Add(temp) ' MsgBox(dt.Rows.Count) Next SelectedGrid.Rebind() End Sub 'Remove from Selected Protected Sub SelectedRowDrop(sender As Object, e As Telerik.Web.UI.GridDragDropEventArgs) Handles SelectedGrid.RowDrop End Sub End Class

Hi Brad,
Try implementing advanced data-binding for the second RadGrid and see if this fixes the issue:
Advanced Data-binding (using NeedDataSource event)
