事件如何相互调用

[yanele]

有一个dataGridView1控件,写好了下面两个验让事件

private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
{
}

private void dataGridView1_RowValidating(object sender, DataGridViewCellCancelEventArgs e)
{
}

我想在dataGridView1_Leave事件中直接调用上面两个验证事件,该如何调用?主要不知道如何传入DataGridViewCellValidatingEventArgs 与DataGridViewCellCancelEventArgs 类.

private void myDataGridView1_Leave(object sender, EventArgs e)
{
    dataGridView1_CellValidating(sender,?);
    dataGridView1_RowValidating(sender,?);
}

嗯，为什么不在前台写JS验证呢？

不好意思,是WinForm程序,没有说清楚,主要不知道怎么传第二个参数.上面两个事件用到了e作为方法调用.

[yanele]

楼上的方法不报错了,但传入的e参数是null,跟踪执行到上面的方法里需要e.RowIndex判断就有问题了.

事件这样简单调用就可以了：

        private void button1_Click(object sender, EventArgs e)
        {
            this.button2_Click(sender, e);
        }

        private void button2_Click(object sender, EventArgs e)
        {
            MessageBox.Show("button2 has been clicked");
        }

[夜轻风]

        private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
        {
            MessageBox.Show("111");
        }

        private void dataGridView1_RowValidating(object sender, DataGridViewCellCancelEventArgs e)
        {
            MessageBox.Show("222");
        }

        private void dataGridView2_Leave(object sender, EventArgs e)
        {
            this.dataGridView1_CellValidating(sender,e as DataGridViewCellValidatingEventArgs);
            this.dataGridView1_RowValidating(sender, e as DataGridViewCellCancelEventArgs);
        }
