Wanting to "call" an event handler is a bit unusual. Can you clarify what it is that you mean? You *could* simply call the event handler just like any other method call passing null or Nothing as the parameters.

I have code in keydown event as:
If e.key = key.enter or e.key = key.tab Then
textbox1.focus()
End If

And in PreviewLostKeyboardFocus I retrive values for other textboxes. If I press Tab key it works fine but if I press Enter key,previewlostkeyboardfocus event is not called.

That is because the Enter key does not cause the textbox to lose or change focus.

Then is there any other option by which I can use Enter key to loose focus?
