KeyPress

KeyPress(KeyAscii)

This event occurs when an E3Browser has the keyboard focus and users press a key corresponding to a character that can be showed on Screen (an ANSI key, with a code indicated by the KeyAscii parameter), that is, this event occurs when any of the following keys is pressed:

Any keyboard character that can be printed

The CTRL key combined with any standard alphabet character

The CTRL key combined with any special character

The BACKSPACE key

The ESC key

 

This event does not occur in the following conditions:

By pressing the TAB key

By pressing the ENTER key

By pressing the DEL key (this is not an ANSI key)

By pressing keyboard arrow keys

When a key changes the focus from one object to another

 

While users press a key that produces an ANSI code, an E3Browser repeatedly receives the KeyDown and KeyPress events. When users release that key, the KeyUp event occurs. To monitor the physical status of a keyboard or to handle keys not recognized by the KeyPress event, such as function keys or browsing keys, use the KeyDown and KeyUp events.

 

NOTE

For a list with all key codes available for the KeyAscii parameter, please check the article Keys Enumeration on Microsoft Developer Network.
