为什么在文本框离开事件后没有触发按钮单击事件？

Question

I have text box with leave event

    private void textBox1_Leave(object sender, EventArgs e)
    {
        MessageBox.Show("Leave");
    }

and button with click event

    private void button1_Click(object sender, EventArgs e)
    {
        MessageBox.Show("Click");
    } 

When I enter text in textbox and click the button the leave event fires but click event does not.

How do I fire the click event without invoking button1_Click in the leave event?

Answer 1

Simply replace MessageBox.Show with Console.WriteLine in the textBox1_Leave and you will see the button's click event. In other words, it seems that user interaction in the Leave event breaks events chain, because of the focus was captured by MessageBox .
