    Good morning.

                I have a problem with the vertical scrollbar in a toolwindow. I use your RadControls for WinForms Q3 2009 release. I did the following steps:


    1. New project, WindowsForm Application (with Visual Basic 2008 Express Edition).
    2. Insert a RadDock, “Dock new window to left”. This is ToolWindow1.
    3. Insert a radPanelBar in the toolwindow, dock = fill, groupstyle = explorerBarStyle.
    4. By clicking on a button, the radPanelBar is programmatically filled with RadPanelBarGroupElement:


      Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click


        For i As Integer = 0 To 10

          Dim ri As New Telerik.WinControls.UI.RadPanelBarGroupElement

          ri.Caption = "GroupItem" & i



      End Sub


    If the form is small enough, you can see that no vertical scrollbar appears. As soon as you click on a groupitem, the scrollbar appears. If you click the button again, again the scrollbar disappears. What can I do to solve this problem?


    Thank you.

    Good morning.

                Regarding this problem, I tried to use your new RadControls for WinForms Q1 2010. If you try with the same test project as above, you will notice that the vertical scrollbar doesn’t appear, as before. The only improvement is that now, when you click on a groupitem, the vertical scrollbar appears and doesn’t disappear anymore, but when you programmatically add groupitems to the radPanelBar, again no vertical scrollbar is displayed. Any suggestion? Thank you very much.

    Hello Franco,

    I tested the case with Q1 2010 SP2 (v2010.1.10.504), but I was not able to reproduce the described behavior on my side. I am attaching a sample project to demonstrate that the scrollbar appears initially. Please update your Telerik version if you have not done it so far. Generally, we are developing a new control that will be the successor of RadPanelBar. This control is called RadTabView and you can find more information about it here.

    Kind regards,
    the Telerik team
