Obtaining reference to Control in its Event Handler

[infimo]

Hi!

How do you obtain a reference to a control from its event handler without knowing the name of that control?

On my form I have some textboxes that have the same code in all their LostFocus and GotFocus events. The only difference is the name of that control itself.

I was wondering if I could create a base textbox with these event handlers coded in and make all my textboxes inherit this textbox... That would make my code much shorter.

Thanks in advance.

just inherit the control

and then make the lostfocus and gotfocus event

and use the me or mybase keyword to refer to the control itself. the compiler will know what to do.

Infimo,

You do not need to inherit anything.

By convention, the first paramater passed to every event is the sender, the object that raised the event.

Private Sub txtFormatString_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles txtFormatString.TextChanged, txtFormat2.TextChanged
' Treat sender as a TextBox
Dim txt As TextBox = DirectCast(eventSender, TextBox)
Dim txtName As String = txt.Name
......
End Sub
