Put current user name into the session and compare on row binding. Add role checking and you're done. Admin will have right regardless of the user name and particular user will get his edit on his own rows.

I guess it's Windows app since OP has mentioned "datagridview"

try something like this

string userName = GetCurrentUser();
           string role = GetRole(userName);

           if(role != "Admin")
           for (int i = 0; i < dataGridView1.Rows.Count; i++)
           {
               if ((dataGridView1.Rows[i].Cells["UserName"].Value != userName))
               {
                   dataGridView1.Rows[i].ReadOnly = true;
               }
           }

refer DataGridViewRow.ReadOnly Property (System.Windows.Forms)[^]
