Not sure if this is intented or not but I've got a XamTextEditor with text "Name1_1" when IsReadOnly = false (default) it displays that string.
However if I set IsReadOnly = true it displays "Name11", if I get the Text and print it out within the code it displays the original text so it appears the character is only dropped when displayed.
Is there some setting that can be used to prevent this character from being dropped? Or a style?
The only time I've seen that type of behavior is when a ContentPresenter is used and its RecognizesAccessKey is set to true (or if you use an AccessText element directly). Our templates for the xamTextEditor don't use a ContentPresenter or an AccessText element so I don't know why you would see that behavior. Do you have an example that demonstrates that issue?
I'll try to create a simple sample based on the code I'm using, of course knowing my luck the simple example will work perfectly
