Property Value

Type Default Description
Int32

0

An integer value specifying the width of the menu bar in pixels.

Remarks

If the MenuBarWidth property value is 0, the menu bar is not displayed. Change this property value to display the bar. The image below displays the default appearance of a popup menu when the MenuBarWidth property is set to 20.

MenuBar - PopupMenuStandard

Nothing is painted in the menu bar by default. You must handle the PopupMenu.PaintMenuBar event to paint the menu bar's contents. This event provides parameters that allow you to obtain the painting surface and the bounding rectangle of the bar.

Examples

The following sample code handles the PopupMenu.PaintMenuBar event. The handler fills the menu bar area with a linear gradient brush and paints "XtraBars Suite" on it.

The image below displays an example of using such a PopupMenu.PaintMenuBar event handler. (Note that the PopupMenu.MenuBarWidth property of the corresponding popup menu should be set to 20 to obtain similar output).

MenuBar - PopupMenuCustom

using System.Drawing;
using System.Drawing.Drawing2D;

readonly Font textFont = new Font("Tahoma", 11, FontStyle.Bold);
private void popupMenu1_PaintMenuBar(object sender, 
  DevExpress.XtraBars.BarCustomDrawEventArgs e) {
   // filling the background
    using(var backBrush = new LinearGradientBrush(e.Bounds, Color.Black,
        Color.Blue, LinearGradientMode.Vertical))
        e.Graphics.FillRectangle(backBrush, e.Bounds);

    // formatting the output string
    using(var outStringFormat = new StringFormat()) {
        outStringFormat.Alignment = StringAlignment.Near;
        outStringFormat.LineAlignment = StringAlignment.Center;
        outStringFormat.FormatFlags |= StringFormatFlags.DirectionVertical;

        // transforming the painting surface and modifying the bounding rectangle
        // this is needed to provide proper string orientation
        e.Graphics.RotateTransform(180);
        Rectangle rect = e.Bounds;
        rect.Offset(-rect.Width, -rect.Height);

        // painting the string
        e.Graphics.DrawString("XtraBars Suite", textFont,
            Brushes.White, rect, outStringFormat);
        e.Graphics.ResetTransform();
    }

    // prohibiting default painting
    e.Handled = true;
}
