TDBEdit.KeyPress Method
TDBEdit Class | TDBEdit Members | DBCtrls Namespace | Description | See Also
Collapse All

Supplements the inherited method to handle any keystrokes that alter the state of the edit control.

Pascal
procedure KeyPress(var Key: Char); override;
C++
virtual __fastcall KeyPress(Char Key);
Description

KeyPress first calls the inherited method, which calls the OnKeyPress event handler. Next, KeyPress discards the keystroke if it is not a valid character for the field type, or if there is no link to a database field. Valid characters cause KeyPress to attempt to put the dataset into edit mode.  

Pressing the Escape key causes KeyPress to call Reset, throwing away all unposted edits.

Note: KeyPress is a protected method. Applications cannot call it directly. It is called automatically in response to user actions.
