A TwoWay or OneWayToSource binding cannot work on the read-only property
提问by Tony Trembath-Drake
I've a read only property I need to display in a textbox, and getting this error at runtime. I've set IsEnabled="False", IsReadOnly="True"- no luck.
Other searches say the readonly should fix it, but not for me.
I've got an ugly workaround by adding a dummy setter...
我有一个只读属性，需要在文本框中显示，并在运行时收到此错误。我已经设置IsEnabled="False"，IsReadOnly="True"- 没有运气。其他搜索说 readonly 应该修复它，但不适合我。通过添加一个虚拟二传手，我有一个丑陋的解决方法......

It's hard to guess without code, but you should be able to set the BindingMode to OneWay.
没有代码很难猜测，但您应该能够将 BindingMode 设置为 OneWay。
<TextBox Text="{Binding Path=MyProperty, Mode=OneWay}" />
or from code:
或从代码：
Binding binding = new Binding();
binding.Mode = BindingMode.OneWay;
