NavBarCalcGroupClientHeightEventArgs.Height Property

Gets or sets the group's client area height.

Namespace: DevExpress.XtraNavBar

Assembly: DevExpress.XtraNavBar.v20.1.dll


public int Height { get; set; }
Public Property Height As Integer

Property Value

Type Description

An integer value specifying the height of the group's client area in pixels.


When the NavBarGroup.CalcGroupClientHeight event is invoked, the automatically calculated group client area height is assigned to the Height property. Assign a value to this property to implement custom height for the group' client area.


The following sample code handles the NavBarControl.CustomDrawGroupClientForeground event to custom paint the text on a group's client foreground. The group doesn't contain any links initially and thus the NavBarGroup.CalcGroupClientHeight event is handled to specify the group's height.

The image below shows the result.

CustomDraw - GroupClientForeground

using DevExpress.XtraNavBar.ViewInfo;
using DevExpress.XtraNavBar;

readonly Font mailFont = new Font("Verdana", 8, FontStyle.Bold);
readonly Font siteFont = new Font("Verdana", 8);
private void navBarControl1_CustomDrawGroupClientForeground(object sender, 
  CustomDrawObjectEventArgs e) {
    // Identifying the processed group.
    NavGroupClientInfoArgs info = e.ObjectInfo as NavGroupClientInfoArgs;
    if(info.Group.Caption != "Support Info") return;

    // Specifying the text rectangle.    
    Rectangle rect = e.RealBounds;
    rect.Height /= 4;

    // Formatting the output string.
    using(var outStringFormat = new StringFormat()) {
        outStringFormat.Alignment = StringAlignment.Near;
        outStringFormat.LineAlignment = StringAlignment.Center;

        // Painting the first string.
        rect.Offset(0, rect.Height);
        e.Cache.DrawString("E-mail:", mailFont,
            Brushes.Black, rect, outStringFormat);

        // Painting the second string.
        rect.Offset(0, rect.Height);
        e.Cache.DrawString("", siteFont,
            Brushes.Black, rect, outStringFormat);

    // Prohibiting default painting.
    e.Handled = true;

private void navBarGroup2_CalcGroupClientHeight(object sender, 
  NavBarCalcGroupClientHeightEventArgs e) {
   e.Height = 70;
