>I would like to click() another button on an ASP.NET page during a click() event of another button, similar to what we can do in VFP. Is this possible?

Depending on what you are doing, refactoring will probably give you the most flexible design:

public void Button1_Click (object, eventargs)
{
   DoSomething();
}

public void Button2_Click (object, eventargs)
{
   DoSomething();
}

public void DoSomething ()
{
...
}

Then you can call DoSomething anywhere its needed.
