DataGridView Control Question

[hdbbdh]

Hi everyone,
I don’t know how I will ask, but I will explain to you what I want exactly.
I have DataGridView control in my form, and when the form is started, the DataGridView will has some rows.
Now I need to allow the user to add new rows and edit only the new rows.
For example, let’s say I have these rows
Office IP
--------- ---
General Manager 103
IT 107
Safety 104

These rows will appear when the form is loaded (I will call these rows as group1), and the user can add additional rows (as group2) like:
Office IP
--------- ---
Production 105
Laboratory 108
Security 110

The user can modify group2 rows (Add, Delete and Edit), but he can not modify the group1 rows.

Now, How I can do that?
Note1: Office and IP are the column name.
Note2: Group1 rows is taken from Access Database.

Thank you

If the columns are always going to be the same you could start off by putting them in to the dataGridView(hardcoded) first of all, Have a search around google no one will write the code for you here
