我正在完成以下教程：
我已经在步骤8达到了期望的输出（链接办公室导航栏和导航栏控件），但是在步骤10却无法实现期望的输出（更改导航页面以显示不同的标签，具体取决于选定的导航栏组）。
这是我的Form1.Designer.cs：
namespace dev_express_again
{
partial class Form1
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()

#endregion
private DevExpress.XtraBars.Navigation.NavigationFrame navigationFrame1;
private DevExpress.XtraBars.Navigation.NavigationPage navigationPage1;

private DevExpress.XtraNavBar.NavBarGroup navBarGroup1;
private DevExpress.XtraNavBar.NavBarGroup navBarGroup2;
private DevExpress.XtraBars.Navigation.OfficeNavigationBar officeNavigationBar1;
private DevExpress.XtraEditors.LabelControl labelControl1;
private DevExpress.XtraEditors.LabelControl labelControl2;
}
}
还有我的Form1.cs：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace dev_express_again
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
navigationPage1.Tag = navBarGroup1.Caption = navigationPage1.Caption = "Employees";
navigationPage2.Tag = navBarGroup2.Caption = navigationPage2.Caption = "Customers";
officeNavigationBar1.NavigationClient = navBarControl1;
}
private void navBarControl1_ActiveGroupChanged(object sender, DevExpress.XtraNavBar.NavBarGroupEventArgs e)
{
navigationFrame1.SelectedPage = (DevExpress.XtraBars.Navigation.NavigationPage)navigationFrame1.Pages.FindFirst(x => (string)x.Tag == e.Group.Caption);
}
}
}
据我所知，两者都与本教程完全相同。运行代码时，我会看到一个窗口，该窗口与本教程中的窗口完全相同。当我在办公室导航栏中更改选择时，它会反映在导航栏控件中，但不会更改导航页面。
关于我想念的东西有什么想法吗？
答案 0 :(得分：0)
找出解决方案。忽略了该教程，您还必须在Form1.cs中添加行navBarControl1.ActiveGroupChanged += new DevExpress.XtraNavBar.NavBarGroupEventHandler(navBarControl1_ActiveGroupChanged);，以使用户更改活动组可以实际调用navBarControl1_ActiveGroupChanged函数。
