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).
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.
