InlineUIContainer & 中的控件在 RichTextBox.Document 中始终禁用 BlockUIContainer [英] Controls in InlineUIContainer & BlockUIContainer always disabled in RichTextBox.Document

问题描述

例如，如果我有如下代码，两个按钮都被禁用:

For example if i have code like the following both Buttons are disabled:

<RichTextBox>
    <FlowDocument>
        <BlockUIContainer>
            <Button Content="!"/>
        </BlockUIContainer>
        <Paragraph>
            <InlineUIContainer>
                <Button Content="!"/>
            </InlineUIContainer>
        </Paragraph>
    </FlowDocument>
</RichTextBox>

我不知道为什么会这样，或者我可以做些什么来防止这种情况发生，显然禁用的按钮不是很有用，因此我们将不胜感激.

I have no idea why this is the case or what i can do to prevent this, obviously disabled buttons are not very useful so any help to resolve this would be appreciated.

事实证明 FlowDocument 由于某种原因被禁用，但是我还没有找到重新启用它的方法，因为它变回 IsEnabled="False" 立即...

It turns out that the FlowDocument gets disabled for some reason, however i have not found a way to reenable it yet, since it changes back to IsEnabled="False" immediately...

推荐答案

实际上有一个名为 IsDocumentEnabled(.NET 3.5 以上)在 RichTextBox 本身上，可以设置为 true 以启用文档.

There actually is a property called IsDocumentEnabled (.NET 3.5 onwards) on the RichTextBox itself that can be set to true to enable the document.
