[英]Context Menu in WPF without XAML
I am trying to design an application with 256 button inside. 我正在尝试设计一个带有256个按钮的应用程序。 These buttons are added by using "for" loop in c#, so they are not in the
XAML
code. 这些按钮是通过在c#中使用“ for”循环添加的,因此它们不在
XAML
代码中。 My problem is that - I don't know how to add a Context Menu to such a button. 我的问题是-我不知道如何向这样的按钮添加上下文菜单。 The context menu should open when clicking right mouse button on particular button.
在特定按钮上单击鼠标右键时,上下文菜单应打开。 Then I want to be able to change some variable in code, when selecting some of the context menu item.
然后,我希望能够在选择某些上下文菜单项时更改代码中的某些变量。
My code for adding buttons is following: 我添加按钮的代码如下:
public MainWindow()
{
InitializeComponent();
int num = number(3);
for(int i =0; i<(num*num); i++)
{
//i want initialize the context menu here
Button button = new Button();
button.Name = "Butt" + counter;
button.Content = "New";
counter++;
button.Height = 35;
button.Width = 35;
button.Click += new RoutedEventHandler(NewButton_Click);
wp.Children.Add(button); // Wrap Panel where buttons displayed
}}
You can create a context menu like this: 您可以创建一个上下文菜单,如下所示:
ContextMenu c = new ContextMenu();
MenuItem i1 = new MenuItem();
i1.Header = "Some Header";
i1.Click += i1_Click;
c.Items.Add(i1);
and attach it to a button like this: 并将其附加到这样的按钮上:
button.ContextMenu = c;
