How do I find Last active control

Question

Hi,

I have multiple text boxes and buttons.
On print button I am saving form as .xps  using Me.PrintForm1.Print and I need to unselected all text boxes before this
and then again select same text box after save. Please suggest how can i do this functionality.

I tried with this.Activecontrol but always getting clicked button(i.e. print button). how I'll get last active control or is there any alternative.

Thanks
