BindableObject.BindingContextProperty 欄位

定義

命名空間:

Microsoft.Maui.Controls

組件:

Microsoft.Maui.Controls.dll

的 BindingContext可系結屬性。

public: static initonly Microsoft::Maui::Controls::BindableProperty ^ BindingContextProperty;

public static readonly Microsoft.Maui.Controls.BindableProperty BindingContextProperty;

 staticval mutable BindingContextProperty : Microsoft.Maui.Controls.BindableProperty

Public Shared ReadOnly BindingContextProperty As BindableProperty 

欄位值

BindableProperty

備註

一般而言，如果在 BindingContext 進行所有呼叫 SetBinding(BindableProperty, BindingBase) 之後設定，運行時間效能會更好。

下列範例示範如何將系結設定為 BindingContext：

class PersonView : ContentView 
{
  public PersonView ()
  {
    var label = new Label ();
    label.SetBinding (Label.TextProperty, "Name");
    Content = label;
  }
}

var stack = new StackLayout {
  Orientation = StackOrientation.Vertical,  
};

var jane = new PersonView ();
jane.SetBinding (BindableObject.BindingContext, "Jane");
stack.Children.Add (jane);

var john = new PersonView ();
john.SetBinding (BindableObject.BindingContext, "John");
stack.Children.Add (john);

stack.BindingContext = new {Jane = new {Name = "Jane Doe"}, John = new {Name = "John Doe"}};
