The table below describes the mask characters that can be used when the MaskType property is set to Standard.
|0||Digit, required. This element will accept any single digit between 0 and 9.|
|9||Digit or space, optional.|
|#||Digit or space, optional. If this position is blank in the mask, it will be rendered as the character in the PromptChar property. For example, "$######.##" displays as a literal "$", accepts a numeric amount with six places and two places to the right of the decimal, i.e. $123456.56.|
|L||Accepts letters only.|
|A||Alphanumeric, required. Accepts any symbol.|
|<||Shift down. Converts all characters that follow to lowercase.|
|>||Shift up. Converts all characters that follow to uppercase.|
||||Disable a previous shift up or shift down.|
|\||Escape. Escapes a mask character, turning it into a literal. "\" is the escape sequence for a backslash.|
|All other characters||All non-mask elements will appear as themselves within RadMaskedInput . Literals always occupy a static position in the mask at run time, and cannot be moved or deleted by the user|
By default, when the user is typing before already typed text, the text is overridden. If the Insert key is pressed you can insert characters instead of replacing them.
