.NET MAUI MaskedEntry Prompt Character
Updated on Jun 25, 2026
The MaskedEntry exposes a PromptChar(char) property, which represents a symbol (char) for any mask position that the user has not filled in yet. The default PromptChar value is _ (underscore).
You can also control whether the prompt character is treated as a valid input character through the AllowPromptAsInput (bool) property.
