右键单击菜单项并显示选项
我有菜单 ServerList,我使用 C# 代码动态添加菜单项。它从文件中读取服务器列表并填充菜单项。我为每个服务器添加了右键单击选项。编辑&删除。
这一切都运行良好。问题是单击“编辑/删除”时如何读取实际服务器名称。
这是代码
public MainWindow()
{
InitializeComponent();
LoadMenuItems();
}
//Currently static values, but reads from file. later
private void LoadMenuItems()
{
MenuItem item2 = new MenuItem();
item2.Header = "Server1";
AddContextMenu(item2);
MenuItem item3 = new MenuItem();
item3.Header = "Server2";
AddContextMenu(item3);
ActualMenu.Items.Add(item2);
ActualMenu.Items.Add(item3);
}
private void AddContextMenu(MenuItem item)
{
MenuItem item1 = new MenuItem();
item1.Header = "Edit";
item1.Click += item_Click;
MenuItem item2 = new MenuItem();
item2.Header = "Detlete";
item2.Click += item_Click;
ContextMenu menu = new ContextMenu();
menu.Items.Add(item1);
menu.Items.Add(item2);
item.ContextMenu = menu;
}
void item_Click(object sender, RoutedEventArgs e)
{
MenuItem item = sender as MenuItem;
string header = item.Header.ToString();
}
I have menu ServerList, I am adding the menuItems dynamically using C# code. It reads the servers list from file and populate the menu items. I have added the right click options for each server. Edit & Delete.
All this is working fine. the problem is how do I read actual server name when Edit/Detele is clicked.
Here is the code
public MainWindow()
{
InitializeComponent();
LoadMenuItems();
}
//Currently static values, but reads from file. later
private void LoadMenuItems()
{
MenuItem item2 = new MenuItem();
item2.Header = "Server1";
AddContextMenu(item2);
MenuItem item3 = new MenuItem();
item3.Header = "Server2";
AddContextMenu(item3);
ActualMenu.Items.Add(item2);
ActualMenu.Items.Add(item3);
}
private void AddContextMenu(MenuItem item)
{
MenuItem item1 = new MenuItem();
item1.Header = "Edit";
item1.Click += item_Click;
MenuItem item2 = new MenuItem();
item2.Header = "Detlete";
item2.Click += item_Click;
ContextMenu menu = new ContextMenu();
menu.Items.Add(item1);
menu.Items.Add(item2);
item.ContextMenu = menu;
}
void item_Click(object sender, RoutedEventArgs e)
{
MenuItem item = sender as MenuItem;
string header = item.Header.ToString();
}

默认情况下,MenuItem 的 Header 使用 TextBlock 来显示内容。因此,在这种情况下,您需要将 Header 转换为 TextBox,然后查看 Text 属性。
例如,
By default, the Header of a MenuItem uses a TextBlock to display content. So, in this case you need to convert the Header to a TextBox, then look at the Text property.
For example,
