Answer 1

You can use CellEndEdit event for DataGridView .

Then you can access cell value using following code

((DataGridView)sender).Rows[e.RowIndex].Cells[e.ColumnIndex].Value

I just displayed data in the cell in messagebox. Code will look like:

 private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
    {
        MessageBox.Show(((DataGridView)sender).Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString());
    }
