RadGridView scrollbar not scrolling

[Oliver]

I have placed a RadGridview in a toolWindows of a RadDock.
When I click on the down/up arrow of the scrollbar, it worked. As soon as I drag the scrollbar, either up or down. It stopped working thereafter.

Am I missing something?

Hello Oliver,

This should work just fine. What version of the controls are you using?

Here is a very simple exmaple to try in a new project.

Designer File

<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class Form1
    Inherits System.Windows.Forms.Form

    'Form overrides dispose to clean up the component list.
    <System.Diagnostics.DebuggerNonUserCode()> _
    Protected Overrides Sub Dispose(ByVal disposing As Boolean)
        Try
            If disposing AndAlso components IsNot Nothing Then
                components.Dispose()
            End If
        Finally
            MyBase.Dispose(disposing)
        End Try
    End Sub

    'Required by the Windows Form Designer
    Private components As System.ComponentModel.IContainer

    'It can be modified using the Windows Form Designer.
    'Do not modify it using the code editor.

Let me know if that works for you.

Hi Richard,

Sorry for the late reply. I did try you suggested solution. Tried it before I submitted this thread. The scrolling worked without any problems.
However, on another project, I had other controls on the document tab strip. That didn't work. The RadGridView worked fine until I drag the scroll bar. I suspect by dragging the scroll bar on the RadGridView, triggered something else.

Hello Oliver,

If you could post a sample of this issue, I'll be very happy to take a look at it for you.
Regards,
Richard

Hi Oliver,

Since we also cannot reproduce the described issue on our side, I would second the reply of Richard: Could you please open a new support ticket and send us a small sample application, which demonstrates the strange behavior. This will allow us to further your case further and provide you with accurate assistance.

All the best,
Martin Vasilev

I am having the exact same problem.  I did not notice this until I upgraded my project to the most recent version of Winforms using the "Project Update Utility".

Hello Larry,

Thank you for writing.

Could you please open a new support ticket and send me a small sample project, which demonstrates the issue? I am still struggling to reproduce it on my side and this prevents me from investigating it  further.

Kind regards,
