Real VC ++. Net note 2-datagrid cell value acquisition

There are many questions about the DataGrid on the Internet, but there are few answers. The reason is: I think the DataGrid is too new and has too many functions to start.
I don't know much about it, but I hope someone will have a very useful answer when encountering the same problem. Don't let your imagination be killed in the vast search of information.

Project template: VC ++ project --. Net -- Windows form applicationProgram(Windows Forms)
Hypothesis premise: the DataGrid instance object, namely, the maid and the textbox instance object, textbox1
Header file: no additional header file is required.

Code:
Textbox1-> text = datagrid1-> get_item (datagrid1-> currentcell)-> tostring (); // gets the value of the selected cell of the current user, which is displayed in textbox
