I cannot make same width for first and second buttons and thumb. There is always right margins in the buttons. The below is my coding:
            this.PanelElement.Fill.BackColor = Color.Transparent;
            this.PanelElement.Fill.GradientStyle = GradientStyles.Solid;
            this.RootElement.BackColor = Color.Transparent;
            this.RootElement.ForeColor = Color.Transparent;
            ((FillPrimitive)this.VerticalScrollbar.ScrollBarElement.Children[1]).GradientStyle = GradientStyles.Solid;
            ((FillPrimitive)this.VerticalScrollbar.ScrollBarElement.Children[1]).BackColor = FXStyle.ColorForKey("ScrollBarBackColor");
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.FitToSizeMode = RadFitToSizeMode.FitToParentContent;
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonFill.GradientStyle = GradientStyles.Solid;
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonFill.BackColor = FXStyle.ColorForKey("ScrollBarButtonBackColor");
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ArrowPrimitive.ForeColor = FXStyle.ColorForKey("ScrollBarButtonArrowBackColor");
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.BoxStyle = BorderBoxStyle.FourBorders;
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.LeftColor = FXStyle.ColorForKey("ScrollBarButtonLeftTopBorderColor");
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.LeftShadowColor = FXStyle.ColorForKey("ScrollBarButtonLeftTopBorderColor");
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.LeftWidth = 1;
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.TopColor = Color.Yellow;
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.TopShadowColor = Color.Yellow;
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.TopWidth = 1;
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.RightColor = FXStyle.ColorForKey("ScrollBarButtonRightBottomBorderColor");
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.RightShadowColor = FXStyle.ColorForKey("ScrollBarButtonRightBottomBorderColor");
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.RightWidth = 1;
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.BottomColor = Color.Red;
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.BottomShadowColor = Color.Red;
            this.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.BottomWidth = 1;

            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.FitToSizeMode = RadFitToSizeMode.FitToParentContent;
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonFill.GradientStyle = GradientStyles.Solid;
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonFill.BackColor = FXStyle.ColorForKey("ScrollBarButtonBackColor");
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ArrowPrimitive.ForeColor = FXStyle.ColorForKey("ScrollBarButtonArrowBackColor");
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.BoxStyle = BorderBoxStyle.FourBorders;
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.LeftColor = FXStyle.ColorForKey("ScrollBarButtonLeftTopBorderColor");
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.LeftShadowColor = FXStyle.ColorForKey("ScrollBarButtonLeftTopBorderColor");
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.LeftWidth = 1;
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.TopColor = Color.Yellow;
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.TopShadowColor = Color.Yellow;
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.TopWidth = 1;
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.RightColor = FXStyle.ColorForKey("ScrollBarButtonRightBottomBorderColor");
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.RightShadowColor = FXStyle.ColorForKey("ScrollBarButtonRightBottomBorderColor");
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.RightWidth = 1;
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.BottomColor = Color.Red;
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.BottomShadowColor = Color.Red;
            this.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.BottomWidth = 1;

            this.VerticalScrollbar.ScrollBarElement.ThumbElement.GripImage = null;
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbFill.GradientStyle = GradientStyles.Solid;
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbFill.BackColor = FXStyle.ColorForKey("ScrollBarThumbBackColor");
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.PaintUsingParentShape = false;
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.BoxStyle = BorderBoxStyle.FourBorders;
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.LeftColor = FXStyle.ColorForKey("ScrollBarThumbRightBorderColor");
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.LeftShadowColor = FXStyle.ColorForKey("ScrollBarThumbRightBorderColor");
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.LeftWidth = 1;
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.TopColor = Color.Red;
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.TopShadowColor = Color.Red;
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.TopWidth = 1;
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.RightColor = FXStyle.ColorForKey("ScrollBarThumbLeftTopBottomBorderColor");
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.RightShadowColor = FXStyle.ColorForKey("ScrollBarThumbLeftTopBottomBorderColor");
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.RightWidth = 1;
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.BottomColor = Color.Yellow;
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.BottomShadowColor = Color.Yellow;
            this.VerticalScrollbar.ScrollBarElement.ThumbElement.ThumbBorder.BottomWidth = 1;

Please help to fix it. Thank you!

Hi Jason,

Thank you for writing.

I managed to achieve the desired result by applying additional margin to the first and second buttons of the scrollbar element: 
this.radScrollablePanel1.VerticalScrollbar.ScrollBarElement.FirstButton.ButtonBorder.Margin = new Padding(0, 0, -2, 0);
this.radScrollablePanel1.VerticalScrollbar.ScrollBarElement.SecondButton.ButtonBorder.Margin = new Padding(0, 0, -2, 0);

I am also sending you a screenshot of the result on my end.

I hope this helps. Should you have further questions please do not hesitate to write back.
