c＃eventhandling错误

Question

我有方法

private void getValues(object sender, EventArgs e)
    {
        int id = int.Parse(dgvTable.Rows[dgvTable.CurrentRow.Index].Cells[0].Value.ToString());
        var values = from c in v.db.TotalDoc
                     where c.TotalID == id
                     select c.TotalAmount;
        dgvValues.DataSource = values;
    }

和datagridview“dgvTable” 这一行的错误

dgvTable.CellClick += new EventHadler(getValues);

错误文本是：'getValues'没有重载匹配委托'System.EventHandler'

请帮忙！

Answer 1

DataGridView.CellClick方法签名是DataGridViewCellEventHandler，而不是EventHandler类型。将您的方法签名更改为：

private void getValues(object sender, DataGridViewCellEventArgs e)

并将您的声明更改为：

dgvTable.CellClick += new DataGridViewCellEventHandler(getValues);

Answer 2

private void getValues(object sender, DataGridViewCellEventArgs e)
