datagrid视图中的keypress事件？

Question

我需要编写一个简单的函数,当人输入框数时,然后按下按键事件并number of boxes*someamount进入金额列.我使用拖放控件添加了datagridview

我想根据我的研究,这里将编写代码

private void dataGridView1_EditingControlShowing(object sender,
    DataGridViewEditingControlShowingEventArgs e) {

}

但我不知道如何把Keyup事件和访问列numberofboxes and Amount.谢谢

我已经测试了这个并且它通过使用按键事件工作并且将NumberBoxes值乘以someAmount,每次在单元格中输入新数字时它会自动为您计算.

        public Form1()
    {
        InitializeComponent();
        MyDataGridViewInitializationMethod();
    }


    private void MyDataGridViewInitializationMethod()
    {

        dataGridView1.EditingControlShowing +=
    new DataGridViewEditingControlShowingEventHandler(dataGridView1_EditingControlShowing);
    }

    private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        e.Control.KeyPress +=
            new KeyPressEventHandler(Control_KeyPress);
    }

    private void Control_KeyPress(object sender, KeyPressEventArgs e)
    {
        if (char.IsNumber(e.KeyChar))
        {

            string cellValue = Char.ToString(e.KeyChar);
            //Get the column and row position of the selected cell
            int column = dataGridView1.CurrentCellAddress.X;
            int row = dataGridView1.CurrentCellAddress.Y;

            if (column == 1)
            {
            //Gets the value that existings in that cell
            string test = dataGridView1[column, row].EditedFormattedValue.ToString();
            //combines current key press to the contents of the cell
            test = test + cellValue;
            int intNumberBoxes = Convert.ToInt32(test);
            //Some amount to mutiple the numberboxes by
            int someAmount = 10;
            dataGridView1[column + 1, row].Value = intNumberBoxes * someAmount;
            }
        }
    }


}
