that the three columns cannot be edited when the DataGrid is being edited, the display style does not change either. The "Exam Score" and "Pass or not" columns 4 and 5 are editable columns. Once the DataGrid is in the editing status, the two columns are changed from the Label display to the preset textbox editing box, allowing users to edit.
