An unexpected behavior occurs when set a long string in the TextBox

Hello,

This problem happens when I try to put a string with a length greater than 15.684 characters.

The height of TextBox increases abruptly and the TextBox turns into non-editable.

Please, help me handle it

Hi @Rayane Thaís Gomes de Lima France ,

Welcome to Microsoft Q&A!

It is recommended that you use text wrapping and vertical scrollbars to solve this problem.

TextBox Enable multi-line input

 <TextBox AcceptsReturn="True" 
          TextWrapping="Wrap" 
          MaxHeight="52" 
          ScrollViewer.VerticalScrollBarVisibility="Auto"/>

Thank you.
