I just upgraded to the latest release of WinForms and am trying to add controls to a RibbonBarGroup using the following code:
    
Everything builds fine, but when I run the project nothing shows up in the RibbonBarGroup.
                                | private void SetupRibbonBar() | 
| { | 
| RadLabel lblStartDate = new RadLabel(); | 
| lblStartDate.Text = "Start Date"; | 
| lblStartDate.Location = new Point(2, 2); | 
| RadLabel lblEndDate = new RadLabel(); | 
| lblEndDate.Text = "End Date"; | 
| lblStartDate.Location = new Point(2, 24); | 
| RadDateTimePicker StartDate = new RadDateTimePicker(); | 
| StartDate.MinimumSize = new Size(150, 20); | 
| StartDate.Location = new Point(13, 2); | 
| StartDate.Format = DateTimePickerFormat.Short; | 
| RadDateTimePicker EndDate = new RadDateTimePicker(); | 
| EndDate.MinimumSize = new Size(150, 20); | 
| EndDate.Location = new Point(13, 24); | 
| EndDate.Format = DateTimePickerFormat.Short; | 
| RadPanel panel = new RadPanel(); | 
| panel.Controls.AddRange(new Control[] { lblStartDate, lblEndDate, StartDate, EndDate }); | 
| RadHostItem item1 = new RadHostItem(panel); | 
| this.RibbonBarGroupReportPeriod.Items.Add(item1); | 
| } | 
Everything builds fine, but when I run the project nothing shows up in the RibbonBarGroup.
