Fire event on textbox lose focus

I'm trying to call a method as soon as a TextBox on my screen gets 'un-focused' if that makes any sense? The user types in a username and as soon as that textbox loses focus I want to fire an event that checks if that username is indeed available.

Thanks!

This will work:

Go to the "properties" of your textbox. You will see a yellow lightning bolt in the first line tab. There you will find all possible events that can be triggered. Search for "Leave" entry, double-click it. There you can put whatever you want.

There is a Control.Leave in C#, which I think is perfect for your purpose.

you can go to events of the textbox in visual studio, and find the Leave event.

The code generated will be like : 

private void txtbox_Leave(object sender, EventArgs e)
{
            //Check for available operation Code
}
