Description

onChange fires when the user changes data, which includes the following actions:

• Inserts or removes a checkmark in a checkbox

• Selects a different RadioButton in the RadioButton group

• Selects a different item in a tree

• Changes a value in an entryfield

• Changes a value in the text box portion of a spinbox

• Clicks the spinner on a spinbox

• Moves the scroll thumb in a scrollbar object

• Changes a value in a field and moves to another row in a browse

• Changes a value in the test box portion of a combobox.

• If the value is changed by editing the value, onChange fires when the combobox loses focus.

• If the value is changed by navigating to a different item in the combobox's list or dropdown list, onChange fires immediately.

• The onChange event of an OLE object fires each time the record pointer moves from one record to another. The onChange event of a form fires after moving to another record, if the previous record was changed, but only if the form is open and has controls dataLinked to fields.
