Good afternoon.
    I have a problem with RadPanelBar. I use VB Express 2008.
I create a new WinForm project and add a RadPanelBar control. Dock = True, GroupStyle = ExplorerBarStyle.
This is the code:
Imports Telerik.WinControls.UI
Public Class Form1
  Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Dim rpbge As RadPanelBarGroupElement
    For i As Integer = 0 To 10
      rpbge = New RadPanelBarGroupElement
      rpbge.Caption = "Group" & i
      rpbge.EnableHostControlMode = True
    Dim rlc As New RadListControl
    rlc.Height = 2
    rlc.Width = rpbge.ContentPanel.ClientSize.Width
    rlc.Anchor = AnchorStyles.Left Or AnchorStyles.Right Or AnchorStyles.Top
    rpbge.Expanded = True
  End Sub
End Class

- Run the project and scroll down with the vertical scroll bar.
- Collapse and Expand the last group (Group10).
- Now try to scroll down again with the vertical scroll bar and you'll see the flicker.
Is there any solution?
Thank you in advance.

Hi Franco,

I confirm that this issue appears when using the RadPanelBar control. This is an obsolete control and we plan to remove it from our suite. We no longer support it. You can use the RadPageView control instead. For more information about the upgrade process, please refer to the following help article:
