How to: Set Smartphone Input Modes
[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]
You can set the input mode for a TextBox in a Smartphone application to ABC, T9, and numeric input modes as defined by the InputMode enumeration. The InputModeEditor class provides access to Smartphone input methods for entering text.
The AlphaCurrent mode is the preferred input mode value for text boxes used for alpha characters. This mode matches the mode selected by holding down the star (*) key on the Smartphone.
You cannot use InputModeEditor to explicitly change casing settings for alpha input modes. However, the alpha input mode used (T9 or ABC) are retained by the AlphaCurrent input mode when set with the star key.
You can only use InputModeEditor on a Smartphone, and only with a TextBox control.
Example
The following code example shows setting the input mode on three text boxes: Name, Phone, and City. The Name and City text boxes are set with the AlphaCurrent input mode and the Phone text box is set with the Numeric input mode.
To observe how AlphaCurrent works, perform the following procedure:
With the Name text box selected, hold down the star key and enter text using either the T9 or ABC input modes.
Enter text in the City text box. Note that the input mode is the same as the Name text box.
