BindableObject.GetValue(BindableProperty) Method

public object GetValue(Xamarin.Forms.BindableProperty property);

member this.GetValue : Xamarin.Forms.BindableProperty -> obj

The value that is contained in the BindableProperty.

GetValue(BindableProperty) and SetValue are used to access the values of properties that are implemented by a BindableProperty. That is, application developers typically provide an interface for a bound property by defining public property whose get accessor casts the result of GetValue(BindableProperty) to the appropriate type and returns it, and whose set accessor uses SetValue to set the value on the correct property. Application developers should perform no other steps in the public property that defines the interface of the bound property.

class MyBindable : BindableObject
{
  public static readonly BindableProperty MyProperty = 
    BindableProperty.Create<MyBindable, string> (w => w.My, default(string));

  public string My {
    get { return (string)GetValue (MyProperty); }
    set { SetValue (MyProperty, value); } 
  }
}
