c# - Calling click event of a button serverside

How can I click or load the click() event of a button in codebehind?
I already tried

      btn.Click();

but this gives an error. I am using ASP.NET

I will assume that you have a button called Button1 and that you have double clicked it to create an event handler.

To simulate the button click in code, you simply call the event handler:

Button1_Click(object sender, EventArgs e).

e.g. in your Page Load Event

protected void Page_Load(object sender, EventArgs e)
{
    //This simulates the button click from within your code.
    Button1_Click(Button1, EventArgs.Empty);
}

protected void Button1_Click(object sender, EventArgs e)
{
    //Do some stuff in the button click event handler.
}
