Answer 1

Try to add it manually. Into constructor of your window class write:

yourElement.Clicked += new EventHandler(Method);
void Method(~)
{
//logic
}

Where EventHandler is a delegate type of Clicked event, and Method is a method, which have same with EventHandler signature.

This is a bug still present in MonoDevelop 3.0.1. Look below for the full stacktrace. Adding an even manually is like Arman Stepanyan described it.
