keypress event in datagrid view?
I need to write a simple function that when the person enter number of boxes then keypress event fired and `number of boxes*someamount` get in to the amount column. I have added datagridview using drag and drop control

I think so code will be written here according to my research

    private void dataGridView1_EditingControlShowing(object sender,     DataGridViewEditingControlShowingEventArgs e)
        {

        }

But i dont know how to put Keyup event and access column `numberofboxes and Amount`. Thanks
