c# - how to invoke convertback of a control that has a converter assigned to it in wpf

Question

how do i invoke convertback method on a control say textbox or button that has been assigned converter in the xaml markup. I need to get the binding value instead of the displayed value. the content property gives the displayed value but i need the original binding value.

Answer 1

您应该将BindingMode设置为TwoWay. 这将调用您的 ConvertBack 方法。如果您需要实际的原始绑定值，那么我的猜测是创建自定义附加行为并在它的帮助下记住值。
