Description
Occurs when the text for the edit control may have changed.
Vcl.StdCtrls.TEdit.OnChange inherits from Vcl.StdCtrls.TCustomEdit.OnChange. All content below this line refers to Vcl.StdCtrls.TCustomEdit.OnChange.
Occurs when the text for the edit control may have changed.
Write an OnChange event handler to take specific action whenever the text for the edit control may have changed. Use the Modified property to see if a change actually occurred. The Text property of the edit control will already be updated to reflect any changes. This event provides the first opportunity to respond to modifications that the user types into the edit control.
