Hello, and welcome back to my channel! Today, we have a practical and useful C# tutorial for you. We'll be learning how to create a TextBox control that accepts only letters and spaces. This can be handy for various applications where you want to restrict user input to text only. So, let's dive right into it!
The code snippet we'll be using for this is quite str aightforward. We'll handle the KeyPress event of the TextBox to validate and control the input.
This code utilizes regular expressions to check whether the entered character is a letter (lowercase or uppercase) or a space. If it matches, we allow the input. If not, we deny it by setting e.Handled to true, preventing the character from being added to the TextBox.
