C#

using DevExpress.Web.ASPxNavBar;
...
protected void Page_Load(object sender, EventArgs e) {
     NavBarGroup group1 = new NavBarGroup("group1", "group1");
     NavBarItem item1 = new NavBarItem("item1", "item1");

     ASPxNavBar1.Groups.Add(group1);
     group1.Items.Add(item1);

     group1.HeaderTemplate = new MyTemplate();
     group1.HeaderTemplateCollapsed = new MyTemplate1();

}

public class MyTemplate : ITemplate {
     void ITemplate.InstantiateIn(Control container) {
          Label label = new Label();
          label.Text = "The group is expanded";
          container.Controls.Add(label);
     }
}

public class MyTemplate1 : ITemplate {
     void ITemplate.InstantiateIn(Control container) {
          Label label2 = new Label();
          label2.Text = "The group is collapsed";
          container.Controls.Add(label2);
     }
}

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
     Dim group1 As New NavBarGroup("group1", "group1")
     Dim item1 As New NavBarItem("item1", "item1")

     ASPxNavBar1.Groups.Add(group1)
     group1.Items.Add(item1)

     group1.HeaderTemplate = New MyTemplate()
     group1.HeaderTemplateCollapsed = New MyTemplate1()

End Sub

Public Class MyTemplate
     Implements ITemplate
     Private Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn
          Dim label As New Label()
          label.Text = "The group is expanded"
          container.Controls.Add(label)
     End Sub
End Class

Public Class MyTemplate1
     Implements ITemplate
     Private Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn
          Dim label2 As New Label()
          label2.Text = "The group is collapsed"
