How to make scroll buttons visible all the time on WinForms TabControlAdv in single line mode?

Platform: WinForms |
Control: TabControlAdv

Scroll buttons

You can make the scroll buttons visible on the TabControlAdv when it is in single line mode. This can be achieved by creating the custom class and overriding the AdjustScrollButtonDimensions function in the TabControlAdv.


//Sets the TabControlAdv in single line mode.
this.tabControlAdv1.Multiline = false;
public class TabControlExt : TabControlAdv
    public TabControlExt()
        //Initializes the TabControl.
    protected override void AdjustScrollButtonDimensions(ref RectangleF tabPanelBounds, bool scrollNeeded)
        // Init the scrollbuttons used to scroll the tabs, when not already inited.
        if (this.ScrollButtons == null && !this.Multiline)
        // Needs the second argument to enable in order to show the scroll button.
        base.AdjustScrollButtonDimensions(ref tabPanelBounds, true);


Public Class TabControlExt
    Inherits TabControlAdv
    Public Sub New()
        'Initializes the TabControl.
    End Sub
    Protected Overrides Sub AdjustScrollButtonDimensions(ByRef tabPanelBounds As RectangleF, ByVal scrollNeeded As Boolean)
        'Init the scrollbuttons used to scroll the tabs, when not already inited.
        If Me.ScrollButtons Is Nothing AndAlso (Not Me.Multiline) Then
        End If
        'Needs the second argument to enable in order to show the scroll button.
        MyBase.AdjustScrollButtonDimensions(tabPanelBounds, True)
    End Sub
End Class



The TabControlAdv can be set as single line by disabling the Multiline property in the TabControlAdv.
