Introduction

Why another MenuStrip? The standard MenuStrip is too limited in functionality and I couldn't find a custom control written that did all that I wanted. This is a User Control with Microsoft Office 2007 Visual Style. It is simple to use, just drop it on the form, and use it like the normal MenuStrip.

Background

MBMenuStrip is a MenuStrip which inherits all the properties of simple MenuStrip control. I added Microsoft Office 2007 like Visuals in MBMenuStrip. The language used is VB.NET. There are so many classes which provide the same functionality, but for that we have to write minimum two lines of code to add that renderer class in our application. MBMenuStrip is the MenuStrip which already contains MBRenderer class. You Just add the reference of MBMenuStrip.dll and used it by dragging and dropping.

Code

The concept for this MenuStrip came from the Microsoft Office 2007 Right Click Menu. I organized methods of MBMenuStrip into layers like this.

The following methods are responsible for rendering a simple MenuStrip like Microsoft Office.

This method Render Background of MBMenuStrip item:

Protected Overrides Sub OnRenderMenuItemBackground_
	(ByVal e As System.Windows.Forms.ToolStripItemRenderEventArgs)
        If e.Item.Selected Then
            Dim g As Graphics = e.Graphics
            g.SmoothingMode = SmoothingMode.HighQuality
            Dim pa As GraphicsPath = New GraphicsPath()
            Dim rect As Rectangle = New Rectangle(2, 1, e.Item.Size.Width - 2, _
			e.Item.Size.Height - 1)
            DrawArc(rect, pa)
            Dim lgbrush As LinearGradientBrush = New LinearGradientBrush_
            	(rect, Color.White, Color.White, LinearGradientMode.Vertical)
            Dim pos As Single() = New Single(3) {0.0F, 0.4F, 0.45F, 1.0F}
            Dim colors As Color() = New Color(3) {GetColor(0, 50, 100), _
            	GetColor(0, 0, 30), Color.FromArgb(R0, G0, B0), GetColor(0, 50, 100)}
            Dim mix As ColorBlend = New ColorBlend()
            mix.Colors = colors
            mix.Positions = pos
            lgbrush.InterpolationColors = mix
            g.FillPath(lgbrush, pa)
            g.DrawPath(New Pen(StrokeColor), pa)
            lgbrush.Dispose()
        Else
            MyBase.OnRenderMenuItemBackground(e)
        End If
    End Sub

This method renders Image of MBMenuStrip Item:

Protected Overrides Sub OnRenderItemImage_
	(ByVal e As System.Windows.Forms.ToolStripItemImageRenderEventArgs)
        e.Graphics.SmoothingMode = SmoothingMode.HighQuality
        If Not (e.Image Is Nothing) Then
            imageheight = e.Item.Height - offsety * 2
            imagewidth = ((Convert.ToDouble(imageheight) / _
				e.Image.Height) * e.Image.Width)
        End If
        e.Graphics.DrawImage(e.Image, New Rectangle_
		(offsetx, offsety, imagewidth, imageheight))
    End Sub

This method handles painting of MBMenuStrip:

Public Sub DrawArc(ByVal re As Rectangle, ByVal pa As GraphicsPath)
        Dim _radiusX0Y0 As Int32 = _radius, _radiusXFY0 As Int32 = _radius, _
        	_radiusX0YF As Int32 = _radius, _radiusXFYF As Int32 = _radius
        pa.AddArc(re.X, re.Y, _radiusX0Y0, _radiusX0Y0, 180, 90)
        pa.AddArc(re.Width - _radiusXFY0, re.Y, _radiusXFY0, _radiusXFY0, 270, 90)
        pa.AddArc(re.Width - _radiusXFYF, _
	re.Height - _radiusXFYF, _radiusXFYF, _radiusXFYF, 0, 90)
        pa.AddArc(re.X, re.Height - _radiusX0YF, _radiusX0YF, _radiusX0YF, 90, 90)
        pa.CloseFigure()
    End Sub

Using the Code

It is very easy to use the MBMenuStrip in your application. Simply add the reference of the provided DLL to your application and just drag and drop.
