XAML 中的自定义 ItemSource 不可绑定

Custom ItemSource in XAML Not bindable

我创建了一个应该有 ItemSource 的自定义控件。 所以我添加了一个 Bindable属性 并尝试绑定它,但我总是收到以下错误:

"Position 18:46. No property, bindable property, or event found for 'ItemsSource', or mismatching type between value and property. "

绑定:<controls:SeatsView x:Name="Control" ItemSource="{Binding Rows}">

属性:

public IEnumerable ItemSource
{
    get => (IEnumerable)GetValue(ItemSourceProperty);
    set => SetValue(ItemSourceProperty, value);
}
public BindableProperty ItemSourceProperty =
        BindableProperty.Create(nameof(ItemSource), typeof(IEnumerable), typeof(SeatsView), defaultValue: null, defaultBindingMode: BindingMode.TwoWay, propertyChanged: OnItemSourceChanged);

如果我在代码中绑定它,就像 Control.ItemsSource = v.Rows; 它工作正常...

我也尝试添加类型转换器,但它也不起作用

任何想法

Bindable 属性 应该是 staticreadonly

    public static readonly BindableProperty ItemSourceProperty =
    BindableProperty.Create(nameof(ItemSource), typeof(IEnumerable), typeof(SeatsView), defaultValue: null, defaultBindingMode: BindingMode.TwoWay, propertyChanged: OnItemSourceChanged);
