How to trigger a button in code

[Boki]

Hi All,

private void ResendTimer_Tick(object sender, EventArgs e)
{
button_Send.Click();

}

I want to trigger a button click event in code.

I think you know this can't pass, need your advice.


Thanks.
Boki.

Well, the simplest approach is to just call the same method that the
button-click performs - i.e.

private void button1_Click(object sender, EventArgs e) {
Resend();
}
private void timer1_Tick(object sender, EventArgs e) {
Resend();
}
private void Resend() {
//actual code
}

In this case, both handlers share a signature, so another option would
be to hook both events into the same handler:

private void ResendHandler(object sender, EventArgs e) {
//actual code
}

In some specific cases you can't tell which method(s) is(/are)
handling an event; you can ask the button itself to simulate a click:

private void timer1_Tick(object sender, EventArgs e) {
button1.PerformClick();
}

One of those should do...

It does help, I need the 3rd method, thanks.
