you can use jquery...

<input id="txtName" type="text" />

<script type="text/javascript">
    $("#txtName").blur(function () {
        alert("I am not in textbox.");
    });
</script>

You can use Leave event

private void txtbox_Leave(object sender, EventArgs e)
{
        //your Code
}

You can also use,

private void txtbox_LostFocus(object sender, EventArgs e)
{
   //your Code
}

Leave() event first executes keyboard event and then executes mouse event where as LostFocus() event first executes mouse event and then executes keyboard event.

Basically When you change the focus by using the keyboard (TAB, SHIFT+TAB, and so on), the events occurred in the following order

1. Enter
2. GotFocus
3. Leave
4. Validating
5. Validated
6. LostFocus

When you change the focus by using the mouse or by calling the Focus method, focus events occur in the following order:

1. Enter
2. GotFocus
3. LostFocus
4. Leave
5. Validating
6. Validated

Also there is a LostFocus event to do this:

private void txtbox_LostFocus(object sender, EventArgs e)
{
    //your Code
}
