These messages vary widely and I want to have different visual layout (string formats, colors, Fonts, icons, whatever etc.) for each message.

阅读更多关于 Why isn't TextBox.Text in WPF animatable?

问题 Ok, I have just run into something that is really catching me off-guard. I was helping a fellow developer with a couple of unrelated questions and in his project he was animating text into some TextBlock(s). So, I went back to my desk and recreated the project (in order to answer his questions), but I accidentally used TextBox instead of TextBlock . My text wasn't animating at all! (A lot of help, I was!) Eventually, I figured out that his xaml was using TextBlock and mine was using TextBox.

问题 I want all texts in TextBlock , Label , MenuItem.Header to be displayed in upper case.

阅读更多关于 Any way to make a WPF textblock selectable?

I want to make the text displayed in the Witty , an open source Twitter client, selectable. It is currently displayed using a custom textblock. I need to use a TextBlock because I'm working with the textblock's inlines to display and format the @username and links as hyperlinks. A frequent request is to be able to copy-paste the text. In order to do that I need to make the TextBlock selectable. I tried to get it to work by displaying the text using a read-only TextBox styled to look like a textblock but this will not work in my case because a TextBox does not have inlines. In other words, I
