WPF中, 启用添加到RichTextBox中的控件 周银辉WPF中RichTextBox的确非常的强大, 但让人很郁闷的是:添加到其中的控件总是被禁用的(IsEnabled始终为false)参考以下代码: < Window xmlns ="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x ="http://schemas.microsoft.com/winfx/2006/xaml" Title ="LearnWPF - Changing Elements with Styles" Width ="350" Height ="200" > < RichTextBox > <!-- regular FlowDocument --> < FlowDocument FontFamily ="Segoe" FontSize ="12" > < Paragraph > This is some text inside a flowdocument </ Paragraph > < BlockUIContainer > < Button Content ="Click Me?" IsEnabled ="True" > </ Button > </ BlockUIContainer > </ FlowDocument > </ RichTextBox > </ Window > 虽然我们已经将Button的IsEnable属性设置为True,但实际运行时其仍然是被禁用的. 解决方案如下: 重写FlowDocument的IsEnabledCore属性,将其返回值设置为True class MyFlowDocument : FlowDocument { protected override bool IsEnabledCore { get { return true; } } } 然后使用重写了的MyFlowDocument替换FlowDocument就可以了:)
