在WPF中自定义窗体标题栏，首先需要将窗体的WindowStyle属性设置为None，隐藏掉WPF窗体的自带标题栏。然后可以在窗体内部自定义一个标题栏。

　　例如，标题栏如下:

        <WrapPanel Height="30" MouseMove="TitleBar_MouseMove" MouseDown="TitleBar_MouseDown" Background="#4C9CFB" DockPanel.Dock="Top">
            <TextBlock Name="txtTitle" Margin="1,0,0,0"  Padding="5,3,2,3" Text="个人信息" 
                   HorizontalAlignment="Left" VerticalAlignment="Center" FontSize="14" FontFamily="微软雅黑"  
                   Foreground="White"/>
            <custom:ImageButton x:Name="btn_min" Template="{StaticResource ImageButton_Template}" Margin="560,5,0,0"
                            Source="../res/img/btn_min1.jpg" ImgWidth="14" ImgHeight="14" Click="btn_min_Click" Grid.Column="0"/>
            <custom:ImageButton x:Name="btn_max" Template="{StaticResource ImageButton_Template}" Margin="30,5,0,0"
                            Source="../res/img/btn_close1.jpg" ImgWidth="14" ImgHeight="14" Click="btn_close_Click">
            </custom:ImageButton>
        </WrapPanel>

　　在后台，为TitleBar添加了MouseMove事件，后台处理代码:

　　#region 标题栏事件

        /// <summary>
        /// 窗口移动事件
        /// </summary>
        private void TitleBar_MouseMove(object sender, MouseEventArgs e)
        {
            if (e.LeftButton == MouseButtonState.Pressed)
            {
                this.DragMove();
            }
        }

        int i = 0;
        /// <summary>
        /// 标题栏双击事件
        /// </summary>
        private void TitleBar_MouseDown(object sender, MouseButtonEventArgs e)
        {
            i += 1;
            System.Windows.Threading.DispatcherTimer timer = new System.Windows.Threading.DispatcherTimer();
            timer.Interval = new TimeSpan(0, 0, 0, 0, 300);
            timer.Tick += (s, e1) => { timer.IsEnabled = false; i = 0; };
            timer.IsEnabled = true;

            if (i % 2 == 0)
            {
                timer.IsEnabled = false;
                i = 0;
                this.WindowState = this.WindowState == WindowState.Maximized ?
                              WindowState.Normal : WindowState.Maximized;
            }
        }

        /// <summary>
        /// 窗口最小化
        /// </summary>
        private void btn_min_Click(object sender, RoutedEventArgs e)
        {
            this.WindowState = WindowState.Minimized; //设置窗口最小化
        }

        /// <summary>
        /// 窗口最大化与还原
        /// </summary>
        private void btn_max_Click(object sender, RoutedEventArgs e)
        {
            if (this.WindowState == WindowState.Maximized)
            {
                this.WindowState = WindowState.Normal; //设置窗口还原
            }
            else
            {
                this.WindowState = WindowState.Maximized; //设置窗口最大化
            }
        }

        /// <summary>
        /// 窗口关闭
        /// </summary>
        private void btn_close_Click(object sender, RoutedEventArgs e)
        {
            this.Close();
        }

        #endregion 标题栏事件
