WPF Tutorial: TextBox Accepting Only Digits in C# (C-sharp)

In this WPF tutorial, you'll learn how to ensure that a TextBox accepts only numeric input using C# (C-sharp). We'll cover creating a regular expression to match only digits, handling the PreviewTextInput event to restrict input, using the PreviewKeyDown event to prevent spaces, and managing paste operations to block non-numeric characters. By the end of this video, you'll be able to implement input validation to allow only digits in your WPF applications.
