The CellValueChanged event fires after the cell content has been changed as a result of end-user interaction. The list below provides the possible reasons for this event being raised:
The cell content has been modified via the cell in-place editor or formula bar. The cell editor is closed and the entered value is committed to an active cell or selected cells when an end-user clicks outside the edited cell, or presses ENTER, CTRL+ENTER or CTRL+SHIFT+ENTER.
The cell content has been removed when an end-user pressed DELETE.
A new hyperlink has been added to a cell via the Insert Hyperlink dialog, or an existing hyperlink has been modified via the Change Hyperlink dialog.
