Advanced Masked Input
The DevExpress ASP.NET data editors allow you to use masks during editing. Masks are useful when a string entered by an end-user into an editor matches a specific format. For instance, a text editor that accepts date/time values in the 24-hour format only, or only numeric values, or a phone number that only allows an end-user to enter digits into automatically constructed placeholders.
Within the ASPxEditors library, masked input is supported by the following editor types:
-
Text box editors (in particular, the ASPxTextBox and ASPxButtonEdit).
-
Date editors (ASPxDateEdit).
Keyboard Support
Mask sections of some types provide keyboard support. When input focus is within a mask section, end-users can easily modify the masked value using the UP ARROW and DOWN ARROW keys, or the mouse wheel.
Mask Hints
A specific tooltip (mask hint) can be displayed for some mask types, informing end-users about allowed input values. Mask hints might be of considerable assistance for end-users, especially when values are entered using the UP ARROW and DOWN ARROW keys, or the mouse wheel.
