Adding an click event to a programatically added menu item
提问by Boardy
I am working on a C# WPF project and I am storing some items in an SQLite database, when the program loads, it then retrieves the items from the database and adds the items to the menu. What I then need to do is to allow the user to click on one of the added menu items and something is done based on what was clicked. I can't find anything on how to do this, below is the code for how I am adding the menu item to the menu programatically.
我正在处理一个 C# WPF 项目，我将一些项目存储在 SQLite 数据库中，当程序加载时，它然后从数据库中检索项目并将这些项目添加到菜单中。然后我需要做的是允许用户单击添加的菜单项之一，然后根据单击的内容完成某些操作。我找不到有关如何执行此操作的任何信息，以下是我如何以编程方式将菜单项添加到菜单的代码。
StoredDBConnectionManager storedDbConnectionManager = new StoredDBConnectionManager(Properties.Settings.Default.app_dbPassword);
List<string> connections = storedDbConnectionManager.getStoredConnections();
foreach (string connection in connections)
{
mnuFileDBConnections.Items.Add(connection);
}
Thanks for any help you can provide.
感谢您的任何帮助，您可以提供。

Here's an example:
下面是一个例子：
XAML:
XAML：
<Menu Height="23" HorizontalAlignment="Left" Name="menu1" VerticalAlignment="Top" Width="200" />
Code behind:
后面的代码：
public MainWindow() {
InitializeComponent();
MenuItem item = new MenuItem { Header = "test" };
item.Click += new RoutedEventHandler(item_Click);
menu1.Items.Add(item);
}
public void item_Click(Object sender, RoutedEventArgs e) {
MessageBox.Show("Hello!");
}

There should be a MenuItemcontrol you can instantiate and use the connectionas its Headeror Content.
应该有一个MenuItem控件可以实例化并将connection用作它的Headeror Content。
MenuItemwill then have a Clickevent handler against it or you can set the command.
MenuItem然后将有一个Click针对它的事件处理程序，或者您可以设置命令。
Ideally however, you should be retrieving the connectionscollection, setting it to a property on your modeland then have the menubound to that collection, that way it's a simple matter of making use of an ItemTemplatefor the menu.
然而，理想情况下，您应该检索connections集合，将其设置为您的属性model，然后menu绑定到该集合，这样使用ItemTemplate菜单就很简单了。
e.g.
例如
StoredDBConnectionManager storedDbConnectionManager = new StoredDBConnectionManager(Properties.Settings.Default.app_dbPassword);
List<string> connections = storedDbConnectionManager.getStoredConnections();
foreach (string connection in connections)
{
var mi = new MenuItem()
{
Header = connection,
};
mi.Click += ConnectionMenuItemClicked;
mnuFileDBConnections.Items.Add(mi);
}
OR with binding:
或绑定：
<Menu ItemsSource="{Binding Connections}">
<Menu.ItemTemplate>
<DataTemplate>
<MenuItem Header="{Binding}" Click="ConnectionsMenuItem_Clicked">
</MenuItem>
</DataTemplate>
</Menu.ItemTemplate>
</Menu>

foreach(string menuCaption from ...)
{
MenuItem mi=new MenuItem();
mi.Header = meniCaption;
mi.Click += (s,e) =>
{
...
}
}
