推荐答案

以下 - 如何绑定TextBox的SelectionStart属性？，请求类似的问题，并正确地指示 SelectionStart 不能绑定到它是不是依赖属性（这也适用于 SelectionLength ）。进一步提供了几个解决方法;一个使用自定义文本框（这将是我的首选项），另一个使用附加的行为。

The following - "How to bind SelectionStart Property of Text Box?", asks a similar question and correctly indicates that SelectionStart cannot be bound to is it is not a dependency property (and this is true for SelectionLength as well). Further down a couple of work-arounds have been provided; one using custom textbox (this would be my preference), and another using attached behaviours.
