  • You can't. What you can do is clear the text on focus.  I'm not sure what you're trying to accomplish here.

    NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

  • I'm working on a stopwatch. I have 3 textboxes with a maxlength of 2, and when a textbox gets focus i want to overwrite the numer in the textbox, but not only 1 character at a time, starting with the left character.

    So if the textbox has a value of '12' then i what i want is if the textbox gets focus, and i start typing '3' that the '1' will be overwritten so the new value is '32'. That's the same behaviour as that the 'insert key' is off.

    I found a .net example with the following methode:


    This won't work with xaml, so i lokking for replacement code...

  • Use separate TextBoxes for each digit, select the text when focused, and advance the focus to the next box when the text changes.

    Also consider skin controls for the digits.

  • That's one option, but i don't want the complete text selected, but in the textbox one digit at a time. I just want to overwite one character at a time, just like the keyboard 'insert key' set to off...
