RichTextBox的ReadOnly内容不显示图像

Question

I've come across some strange behavior of RichTextBox . I want it to be readonly , but then it doesn't display images when I use richTextBox.LoadFile(path) method to load .rtf file. When it's not readonly the file is loaded correctly and the images are displayed. I am using Windows Forms.

Can I make it up somehow or is it another RTB bug? For now, as a workaround I am using a label to move focus to it while my RTB got focus, but I don't really like this one.

您可以使用一种方法来创建自定义RichTextBox实现，该方法将设置一个捕获readonlystate的RTF内容，将richtextbox设置为ReadOnly = false，设置RTF内容，然后再设置ReadOnly。
