WPF侧面菜单和动态显示项目

Question

我正在创建带有侧面菜单的WPF窗口。 当用户单击侧面菜单项之一时，我要显示某些文本框，下拉菜单，按钮。 这些取决于单击哪个菜单。

我是否需要在xaml中定义所有可能的项目，还是可以在C＃中构建这些项目并动态处理事件？

Answer 1

我已经弄清楚了如何编码和显示不同的网格。 现在，我不知道如何从网格中的控件获取值。 我的代码：

private void MenuItem_Click（object sender，RoutedEventArgs e）{// *数据库菜单单击*

        grdExcel.Visibility = Visibility.Hidden;
        grdDatabase.Visibility = Visibility.Visible;
        //grdDataScrubber.Children.Remove(grdExcel);

        // ... Cast sender object.
        MenuItem item = sender as MenuItem;
        // ... Change Title of this window.
        Title = "Process " + item.Header + " Files";


        //InitializeGrid(grdDatabase, item);
        //AddDatabaseControls();
        //grdDataScrubber.Children.Add(grdDatabase);
    }

    private void MenuItem_Click_1(object sender, RoutedEventArgs e)
    {
        //***  Excel Menu Click  ***
        Label lblExcelInfo = new Label();

        grdDatabase.Visibility = Visibility.Hidden;
        grdExcel.Visibility = Visibility.Visible;
        //grdDataScrubber.Children.Remove(grdDatabase);

        // ... Cast sender object.
        MenuItem item = sender as MenuItem;
        // ... Change Title of this window.
        Title = "Process " + item.Header + " Files";

        //InitializeGrid(grdExcel);
        //lblExcelInfo.Content = "In Excel";
        //grdExcel.Children.Add(lblExcelInfo);
        //grdDataScrubber.Children.Add(grdExcel);
    }


    private void InitializeGrid(Grid gridArea)
    {
        gridArea.Height = 330;
        gridArea.Width = 650;
        gridArea.HorizontalAlignment = HorizontalAlignment.Left;
        gridArea.Margin = new Thickness
        {
            Bottom = 0,
            Left = 70,
            Top = 0,
            Right = 0
        };
        gridArea.VerticalAlignment = VerticalAlignment.Top;
        //gridArea.Background = new SolidColorBrush(Color.FromRgb(04, 149, 168));

        grdDataScrubber.Children.Add(gridArea);
    }
