How to make Students Records with DataGridview

How to make Students Records with DataGridview 

1)      Develop an application that allows user to add or remove student information to/from Master list by fulfilling following requirements:

a.      Provide following four input fields for student information (Detail portion):
Student Name, Registration Id, Phone Number, Gender (use ComboBox).

b.      A button to add student record to Master portion (in point c below).

c.       A DataGridView control to keep the list of records added (Master).

d.      Use the DataGridView in read-only mode.

e.      Add four columns to the DataGridView for the data to be added as a complete record.

f.        Use a NumericUpDown control to select the row number desired to be deleted.

g.      Use a button to delete the desired row.

2)      Use a DataGridView similar to the one in task 1 (with four columns) to update records by fulfilling following requirements:

a.      Use a class to keep student information that uses the same 4 fields in task 1 plus two additional fields (Major and Address).

b.      Use the DataGridView in read-only mode but populate it programmatically with 10 records using the objects instantiated using student information class mentioned in step (a).

c.       Upon selecting a row in DataGridView, populate all six fields in Detail portion.

d.      Use a button to update the changes done in Detail portion to the selected record in the list.

e.      Test your application.
