在数据网格视图按键事件？ [英] keypress event in datagrid view?

问题描述

我需要编写一个简单的函数，当人进入的盒子编号，然后按键事件触发，箱数* someamount 获得的金额列。我已经使用拖放控制

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

我想根据我的研究

private void dataGridView1_EditingControlShowing(object sender,
    DataGridViewEditingControlShowingEventArgs e) {

}

但我不知道如何把KeyUp事件和接入列 numberofboxes和金额。谢谢

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

推荐答案

我测试过这一点，它的工作原理是使用键按下事件和倍数 NumberBoxes 按 someAmount 值，每次它会自动计算你的单元格中输入一个新号码的时间。

I've tested this and it works by using the key down event and multiples the NumberBoxes value by someAmount, each time you enter a new number in the cell it does the calculation for you automatically.

        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;
            }
        }
    }


}
