Hi all,
I am supposed to handle an event in my project (c#,, visual studio ).

There are two files related to a form. there is key_down event in both the files.
How can i make out that which file's event is called first.

I have a guess that in one file the events is never called.

Help me out to solve this issue.

Sandeep is right. Just put a break point into both handlers, run your app in debug mode, hit a key and see where you stop first.

Normally, your handlers should be called in the same order of the assignements:

...
{
     //first assignement
     MyEvent += MyEventHandler1;
     //Second assignement
     MyEvent += MyEventHandler2;
}

void MyEventHandler1(object sender, EventArgs e)
{
    //will be called first
}
void MyEventHandler2(object sender, EventArgs e)
{
    //will be called after
}
