Grid update/delete refresh not working

[Marco]

I have read tons of questions regarding the update of the grid ;not working, but I can't seem to find a solution :(
I a grid filled with a list of objects. When I press refresh it updates the lines, but when I add or delete an item the grid is not updated. When I change an object and save, the line IS updated.

My code:

protected override void Page_Init(object sender, EventArgs e)
        {
            base.Page_Init(sender, e);
            CreateGrid();
        }

        protected void Page_Load(object sender, System.EventArgs e)
        {
            lblLocation.Text = Location.Title;
            if (!IsPublished)
            {
                lblStatus.Text = " - " + _location.Status.ToString();
                lblStatus.Visible = true;
            }

            if (_ajaxmanager != null)
            {
                _ajaxmanager.AjaxSettings.AddAjaxSetting(Grid, Grid);
            }
        }

        public void CreateGrid()
        {

            GridButtonColumn edit_col = new GridButtonColumn();
            edit_col.Text = "wijzig";
            edit_col.UniqueName = "EditColumn";
            edit_col.CommandName = "Edit";
            edit_col.ItemStyle.Width = Unit.Pixel(35);

            GridButtonColumn copy_col = new GridButtonColumn();
            copy_col.Text = "kopieer";
            copy_col.UniqueName = "CopyColumn";
            copy_col.CommandName = "Copy";
            copy_col.ItemStyle.Width = Unit.Pixel(40);

            GridButtonColumn del_col = new GridButtonColumn();
            del_col.Text = "verwijder";
            del_col.UniqueName = "DeleteColumn";
            del_col.CommandName = "Delete";
            del_col.ItemStyle.Width = Unit.Pixel(50);

            RadGrid grid = new RadGrid();
            grid.UpdateCommand += new GridCommandEventHandler(grid_UpdateCommand);
            grid.DeleteCommand += new GridCommandEventHandler(grid_DeleteCommand);
            //grid.ItemDataBound += new GridItemEventHandler(grid_ItemDataBound);

            grid.ID = "grdFreeplaces";
            grid.AutoGenerateColumns = false;
            grid.ShowStatusBar = true;
            grid.Width = Unit.Pixel(737);
            grid.ClientSettings.AllowKeyboardNavigation = true;
            grid.ClientSettings.KeyboardNavigationSettings.InitInsertKey = GridFocusKeys.I;

            grid.MasterTableView.EditFormSettings.EditFormType = GridEditFormType.Template;
            grid.MasterTableView.EditFormSettings.FormTemplate = new VisualObjectEditorFreeDaysFormTemplate(this, _location);
            grid.MasterTableView.CommandItemSettings.AddNewRecordText = "Toevoegen";
            grid.MasterTableView.CommandItemSettings.RefreshText = "Herladen";
            if (IsPublished)
                grid.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.TopAndBottom;
            else
                grid.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.None;
            grid.MasterTableView.EditMode = GridEditMode.PopUp;
            grid.MasterTableView.EditFormSettings.PopUpSettings.Width = Unit.Pixel(765);
            grid.MasterTableView.EditFormSettings.PopUpSettings.Height = Unit.Pixel(240);
            grid.DataSource = Location.FreePlaces;
            grid.MasterTableView.DataKeyNames = new string[] { "LexiconItemID" };
            if (IsPublished) grid.MasterTableView.Columns.Add(edit_col);
            if (IsPublished) grid.MasterTableView.Columns.Add(del_col);
            grid.MasterTableView.Columns.Add(CreateDataColumn("Omschrijving", "Description"));
            grid.MasterTableView.Columns.Add(CreateDataColumn("Leeftijd", "AgeRangeDescription"));

            phFreePlace.Controls.Add(grid);
        }

And the command-functions:

        protected void grid_UpdateCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
        {
            bool isnew = false;
            GridEditableItem item = e.Item as GridEditableItem;
            VisualObjectEditor editor = (e.CommandSource as Button).Parent.FindControl("edtFormTemplate") as VisualObjectEditor;
            LexiconItem freeplace = null;

            Location.Location.Document.ContentControl.CheckOut(Framework, Framework.ActiveUser);

            if (item.ItemIndex < 0)
            {
                freeplace = _location.Location.CreateNewFreePlace().LexiconItem;
                isnew = true;
            }
            else
                freeplace = Location.FindFreePlace(item.OwnerTableView.DataKeyValues[item.ItemIndex]["LexiconItemID"].ToString()).LexiconItem;

            editor.GetContentStorageValues(freeplace.Content.DocumentType, freeplace.Content);

            if (editor.Validate(freeplace))
            {
                Location.Location.GetFreePlaceContentField().LexiconItems.Add(freeplace);
                Location.Location.Document.ContentControl.Publish(Framework, Framework.ActiveUser);
                Grid.DataSource = Location.FreePlaces;
                Grid.Rebind();
            }
            else
            {
                Location.Location.Document.ContentControl.UndoCheckOut(Framework, Framework.ActiveUser);
                e.Canceled = true;
            }
        }

        protected void grid_DeleteCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
        {
            Location.Location.Document.ContentControl.CheckOut(Framework, Framework.ActiveUser);
            string lexiconitemid = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["LexiconItemID"].ToString();
            Location.Location.DeleteFreePlace(lexiconitemid);
            Location.Location.Document.ContentControl.Publish(Framework, Framework.ActiveUser);
            Grid.DataSource = Location.FreePlaces;
            Grid.Rebind();
        }

the code is in a control that is created in a main page, if you want' I could add that code as well.

I've tried both the rebind and the NeedDataSource event, but that doesn't make any difference.

I really hope you guy's could help me out with this one.
Thanks

I finally found out that Location.FreePlaces, that was the datasource, was not updated properly and therefore the grid wasn't filled correctly. Stupid me... sorry to bother you
Could you delete the thread?
