I would recommend you use the lostfocus to do that. You can use something like:

this.parent.txtdatebeg.setfocus()

assuming the beginning date textbox sits on the form directly and is named txtdatebeg

if you want to move focus back to that control from another control. You can check in the lostfocus of each control if beginning date is empty and ending date is not or vice versa and display your message and set focus where you need it using the control's setfocus(). You just cannot set focus from a valid. Is it a date or datetime field?
