How To Hide The Prompt Character In .NET MAUI Maskedentry Sfmaskedentry

The HidePromptOnLeave property provides built-in support for hiding prompt characters when the control loses focus.

To hide or display prompt characters after editing, set the HidePromptOnLeave property:

• When HidePromptOnLeave = true, prompt characters are hidden when the control loses focus, resulting in a cleaner display.
• When HidePromptOnLeave = false, prompt characters remain visible even after the control loses focus.

This behavior helps improve readability by displaying only the entered values while still allowing users to see prompt characters during editing.

Benefits of Setting PromptChar to Space

• Removes visible placeholder characters.
• Creates a cleaner input field.
• Improves readability.
• Provides a more modern and minimal UI experience.
• Reduces distractions during data entry.
