我正在创建一个带侧边菜单的WPF窗口。当用户单击其中一个侧面菜单项时，我想显示某些文本框，下拉菜单，按钮。这些将根据单击的菜单而有所不同。
我是否需要在xaml中定义所有可能的项目，还是可以构建这些项目并在C＃中动态处理事件？

我已经想出了如何编码和显示不同的网格。现在我无法弄清楚如何从网格中的控件中获取值。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);
