Hardware Keyboard Event

Can anyone tell me how to detect when the hardware keyboard is used and when 开发者_运维技巧the soft-key-pad is used? Or is there any event which tells that the hardware keypad is shown.

As of Mango, the hardware keyboard detection can now be done - see:

• IsKeyboardDeployed - http://msdn.microsoft.com/en-us/library/microsoft.phone.info.devicestatus.iskeyboarddeployed(v=VS.92).aspx

• IsKeyboardPresent - http://msdn.microsoft.com/en-us/library/microsoft.phone.info.devicestatus.iskeyboardpresent%28v=VS.92%29.aspx

• KeyboardDeployedChanged - http://msdn.microsoft.com/en-us/library/microsoft.phone.info.devicestatus.keyboarddeployedchanged(v=VS.92).aspx
