手动触发事件C＃

Question

I have a button that when clicked displays some information, can i manually trigger the button clicked event in code ?

I need this so that when i click on some other button it automatically triggers this event too.

Answer 1

A good way would be to have NO code (except a method/function call) in an event handler. this would made it possible to call it from any place in your program.

Answer 2

移动代码以响应单击按钮的功能，然后在事件处理程序和另一个事件处理程序中调用该功能。

Answer 3

You can do it like this.

private void button1_Click(object sender, EventArgs e)
{
    MessageBox.Show("button1");
}

private void button2_Click(object sender, EventArgs e)
{
    MessageBox.Show("button2");
    button1_Click(sender, e);
}

Answer 4

如果您不关心发件人或EventArgs，也可以使用

Button1_Click(null, new EventArgs());

Answer 5

您可以使用Button.PerformClick()

Answer 6

There are two ways to do this,

1# -= Move the code which you have written in the button click event to another function and call this function in this button click event and in other button click event also.

2# - For the second button click event specify the first button click event as the event handler.

3# - call button1's event handler inside button2.

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

I will advise you to go for the the second one, if you have to the same set of functionalities for both the buttons.
