"should i use one event for every button click ? or one event to all buttons click", it depends. The only person that can answer your question is you.

Generally speaking, I use a separate event handler method for each separate function, rather than button: if your btn1 opens a file, and btn2 saves a file then I would use separate handler methods. If instead they acted as number buttons on a calculator, I'd use a single method for them all, and use the Tag property of the button to give me the value:

C#

private void NumberButton_Click(object sender, EventArgs e)
    {
    Button b = sender as Button;
    if (b != null)
        {
        int value = (int)b.Tag;
        ...
        }
    }

It's about the functionality, not about the code.
