Cómo: Establecer los modos de entrada de Smartphone
Actualización: noviembre 2007
Puede establecer el modo de entrada de un TextBox en una aplicación para Smartphone como ABC, T9 o numérico, según se defina en la enumeración InputMode. La clase InputModeEditor proporciona acceso a los métodos de entrada de Smartphone para escribir texto.
El modo AlphaCurrent es el valor de modo de entrada preferido para los cuadros de texto de caracteres alfabéticos. Este modo coincide con el modo que se selecciona manteniendo presionada la tecla asterisco (*) del dispositivo Smartphone.
No se puede utilizar InputModeEditor para cambiar explícitamente la configuración de mayúsculas y minúsculas correspondiente a los modos de entrada alfabéticos. Sin embargo, el modo de entrada AlphaCurrent conserva el modo de entrada alfabético utilizado (T9 o ABC) cuando se establece con la tecla asterisco.
Sólo se puede utilizar InputModeEditor en un dispositivo Smartphone, y únicamente con un control TextBox.
Ejemplo
El ejemplo de código siguiente muestra cómo establecer el modo de entrada en tres cuadros de texto: Name, Phone y City. Los cuadros de texto Name y City se establecen con el modo de entrada AlphaCurrent, y el cuadro de texto Phone se establece con el modo de entrada numérico.
Para observar cómo funciona AlphaCurrent, realice el procedimiento siguiente:
Con el cuadro de texto Name seleccionado, mantenga presionada la tecla asterisco y escriba texto usando los modos T9 o ABC.
Escriba texto en el cuadro de texto City. Observe que el modo de entrada es el mismo que en el cuadro de texto Name.
