c# - Execute two buttons with single click

I have a simple C # application that contains buttons and a web browser, each button execute a request and displays the result of the request on the web browser. And use the results of a request in the next button.

private void button1_Click(object sender, EventArgs e)
        {
webBrowser1.Navigate("http://www.test.com");
}

private void button2_Click(object sender, EventArgs e)
        {
            if (webBrowser1.Document.GetElementById("tesxtbox1") != null)
            {
            HtmlElement txt1 = webBrowser1.Document.GetElementById("tesxtbox1");
            txt1.SetAttribute("value", "test");
            webBrowser1.Document.Forms[0].InvokeMember("submit");
            }
        }

Is there any method or way to perform the two buttons with a single click, but the second button, do not execute until the web browser is loaded.

in the first button, I added

webBrowser1.DocumentCompleted + = new WebBrowserDocumentCompletedEventHandler (Button2_Click);

but the second button excuted several times, so I added in the last line of the button 2:

webBrowser1.DocumentCompleted - = new WebBrowserDocumentCompletedEventHandler (Button2_Click);

it works, but in the console I find that Button 2 is execute twice

Thanks in advance!

You shouldn't think like executing second button click. There is DocumentCompleted event which you must listen to and execute neccesary code afterwards.
