Answer 1

You can't implement a button clicked event for button cells in a DataGridViewButtonColumn. Instead, you use the DataGridView's CellClicked event and determine if the event fired for a cell in your DataGridViewButtonColumn. Use the event's DataGridViewCellEventArgs.RowIndex property to find out which row was clicked.

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e) {
    // Ignore clicks that are not in our 
    if (e.ColumnIndex == dataGridView1.Columns["MyButtonColumn"].Index && e.RowIndex >= 0) {
        Console.WriteLine("Button on row {0} clicked", e.RowIndex);
    }
}

The MSDN documentation on the DataGridViewButtonColumn class has a more complete example.

Answer 2

use dataGridView1_CellContentClick instead of dataGridView1_CellClick

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{

    if (e.ColumnIndex == 8) //make sure button index here
    {
          //write your code here
    }

}
