.NET Mobile Input
Input Controls are used to collect input from the mobile user.
Input Controls
There is a number of mobile controls that support user input.
The most common input control is perhaps the TextBox control, which was
demonstrated in the previous chapter. The TextBox control is perfect for simple
user input like names, numbers, identifications and keywords.
For larger amount of input a TextView control is a better choice. The
TextView control allows long multi-line input like the one you need for SMS or
other messages.
Numeric Input
The numeric attribute of the textbox control can be set to true or false to
specify whether the textbox should accept only numeric input.
Note: This behavior will normally work on cell phones by changing the input
mode from letters to numbers. For HTML browsers however, this behavior is
normally not supported.
Password Input
The password attribute of the textbox control can be set to true or false to
specify whether the textbox should be treated as a password field.
A password field will hide the input by displaying * (stars) instead of
ordinary text.
List Controls
TextBox and TextView controls are well suited for entering input, but
sometimes you want the user to select from a list of predefined values.
The SelectionList Control supports drop down lists, check boxes and radio
buttons. This topic is covered in another chapter.
The List Control supports selection from menus and lists. The List Control is covered in another chapter.
