来自另一个控件的C＃触发/调用事件

Question

In VFP9, if i have two buttons (butt1 & butt2) If i want to trigger butt2 click event from butt1 i just do this from butt1 click event butt2.click() and it will call whatever code i have in the procedure/event in butt2. How do i do that in c#?

How do I call event of a certain control from another control like below

.

private void button2_Click(object sender, EventArgs e)
        {
            button1.click()
        }

Answer 1

You can call the handler directly like this button1_Click(button1, null);

Example Usage:

Button button1;
Button button2;

public Form1()
{
    button1.Click += new EventHandler(button1_Click);
    button2.Click += new EventHandler(button2_Click);

}

void button2_Click(object sender, EventArgs e)
{
    button1_Click(button1, null);
}
public void button1_Click(object sender, EventArgs e)
{
    //Action when click occurs
}

Answer 2

Why are you trying to simulate button click, if you just want to execute some logic? Wrap this logic into separate method, an call it from click handlers you choose:

private Foo1() {}

private Foo2() {}

private button1_Click(object sender, EventArgs e)
{
  Foo1();
  Foo2();
}

private button2_Click(object sender, EventArgs e)
{
  Foo2();
}

Answer 3

只需将form_load或designer.cs的button1 click事件绑定到button2 click事件
button2.Click+=new EventHandler(button1_Click);
