如何在自定义contentView中创建可绑定属性 [英] how to create a bindable property in a custom contentView

问题描述

我创建了一个带有图像和标签的自定义ContentView.

I created a custom ContentView with a Image and a Label.

我还创建了ImageUrl和LabelText的属性.

I also created a property of ImageUrl and LabelText.

我希望此ContentView在列表视图中接收绑定值

I want this ContentView an receive a Binding value in a listview

<MyCustomContentView ImageUrl="{Binding Image}" LabelText="{Binding Text}" />

但是它说没有可绑定的属性.如何创建它?

but it says there is no bindable property.how to create it?

推荐答案

您可以使用此代码并将其粘贴到文件后面的代码中MyCustomContentView类的构造函数下方.

You can use this code and paste it below the constructor of the MyCustomContentView class in the code behind file.

        public static readonly BindableProperty LabelTextProperty = BindableProperty.Create(nameof(LabelText), typeof(string), typeof(MyCustomContentView), default(string));
        public static readonly BindableProperty ImageUrlProperty = BindableProperty.Create(nameof(ImageUrl), typeof(string), typeof(MyCustomContentView), default(string));

        public string LabelText { get => (string)GetValue(LabelTextProperty); set => SetValue(LabelTextProperty, value); }
        public string ImageUrl { get => (string)GetValue(ImageUrlProperty); set => SetValue(ImageUrlProperty, value); }
