Textblock, textbox text value does not show "-" char

In my wpf application, textblock text property is binded to string property of an object. String property value is "ABC-XYZ2014-HHH".

But neither textblock or textbox does not show the value correctly. Value is displayed in textblock and textbox as "ABC-XYZ2014-"

I found that Label interpret "_" or "-" as accelerator key but I am using textblock and textbox. But the value after the second "-" does not shown in the textblock and textbox. I can see the correct value in MessageBox.

Solution

Clearly, the end of the text in the TextBlock is getting cut off or hidden by something. You can verify this by adding a new TextBlock with the same text into a different window... you'll see that it works straight away. So the only question here is 'what is hiding the end of the text?'

To find that out, simply set the Background property of the surrounding elements to various colours until you see something with one of those colours over the end of the TextBlock. You'll then know which element is hiding the end of the text.

You set the Width of the TextBlock and TextBox, but you didn't set it on the StackPanel or ScrollViewer. My guess is that your StackPanel is causing the problem because they are not controls that you can use to fit-to-size.
