the problem is, why do I have to press the button twice to trigger the event...lets say

btn.Click += (s,e){
    Response.Write("hello");
};

btn.Click += (s,e){
    Response.Write("hello");
};

I have to click it twice(twice postback) to received hello how to fix this issue?

you start by giving more context what framework is this? what is "aspButton"? what is that snippet of code you posted, and how does it relate to your question?
