All content below this line refers to {{#multireplace:Vcl.StdCtrls.TCustomCombo.OnChange|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}.
Occurs when the user changes the text displayed in the edit region.
Write an OnChange event handler to take specific action immediately after the user edits the text in the edit region or selects an item from the list. The Text property gives the new value in the edit region.
Note: OnChange only occurs in response to user actions. Changing the Text property programmatically does not trigger an OnChange event.
