What's the difference between SetFocus() and Focus() in ASP.NET?

Question

I can use both in the code behind:

SetFocus() - "Sets the browser focus to the specified control."

Focus() - "Sets input focus to a control."

In practice, what's the difference?

Thanks!

Answer 1

From msdn:

To set focus on an ASP.NET Web server control

Call the control's Focus method.

-or-

Call the page's SetFocus method, passing it the ID of the control on which you want to set focus.

Answer 2

Page.SetFocus can accept a control's client ID as a string instead of a reference to the control itself, which may be useful if you can't get a reference to the control to call its Focus method.

control.Focus() is identical to Page.SetFocus(control). In fact, all is does is call SetFocus...

public virtual void Focus()
{
    this.Page.SetFocus(this);
}
