Hi I am new to C#, I have a datagridview that populates student data. I also have a button beside each student row. This button would go to a new form with the student details of that selected student in the first form.

Here is an example of what that would look like. How do I code the button to go to a student details form for that selected student that the button was pressed for?

You say datagridview so you mean Windows Forms application, correct? Not WPF and not DataGrid, correct? If so then the answer from Muhammad Imran Ansari is for you.

@Michelle,
Use the following code to get the value on button click inside the grid and on second form (Student Detail) you have student id and you can show data what you want.
private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    var senderGrid = (DataGridView)sender;
    if (e.RowIndex >= 0 && senderGrid.Columns[e.ColumnIndex] is DataGridViewButtonColumn)
    {
        int studentID = Convert.ToInt32(dataGridView1.Rows[e.RowIndex].Cells["PartId"].EditedFormattedValue);
        frmStudentDetail stdDetail = new frmStudentDetail(studentID);
        stdDetail.ShowDialog();
    }
}
Ovveride constructor of studentdetail form to get id. I have shown student id on form and you can get student detail from data source.
public frmStudentDetail(int StudentID)
{
    InitializeComponent();
    lblStudentID.Text = StudentID.ToString();
}
