How to push a button on a webpage?

Hello marton, a button click is basically an event. And in case of a button, the event gets fired only when the Button is clicked... You cannot explicitly click the button using a program... but if u write some code in the Button Click event, then it gets fired only when the button is clicked...

For example - 

protected void btnSubmit_Click(object sender, Eventargs e)
{
        Response.Write("The User Clicked the Submit Button");
}

Only when the user clicks the button, the text will be shown on the page in the browser....
Hope this helps u out!!!

Please mark the answer as accepted if it helped!!!
Thank you

My problem :
There is a button on a web page. (For example a submit button.) You can click on it with your mouse, of course. 

question:
Is it possible to click the button with a computer program? So I want to write a program that automatically clicks the button. How is it possible?
