可绑定属性问题屏蔽行为

Answer 1

创建

BehaviorBase

来更新您的

behavior

。

public class BehaviorBase<T> : Behavior<T> where T : BindableObject
{
    #region Properties
    public T AssociatedObject
    {
        get;
        private set;
    }
    #endregion
    #region NormalMethods
    private void OnBindingContextChanged(object sender, EventArgs e)
    {
        OnBindingContextChanged();
    }
    #endregion
    #region Overrides
    protected override void OnAttachedTo(T bindable)
    {
        base.OnAttachedTo(bindable);
        AssociatedObject = bindable;
        if (bindable.BindingContext != null)
        {
            BindingContext = bindable.BindingContext;
        }

        bindable.BindingContextChanged += OnBindingContextChanged;
    }
    protected override void OnDetachingFrom(T bindable)
    {
        base.OnDetachingFrom(bindable);
        bindable.BindingContextChanged -= OnBindingContextChanged;
        AssociatedObject = null;
    }
    protected override void OnBindingContextChanged()
    {
        base.OnBindingContextChanged();
        BindingContext = AssociatedObject.BindingContext;
    }
    #endregion
}

让你的

MaskedBehavior

继承

BehaviorBase

。

public class MaskedBehavior : BehaviorBase<Entry>
{
    ……..
 }

和你的用法一样。
