MSFlexgrid in User Form

[excelvish]

Hi All,
I am using Excel 2002. I created one user form with one MSFlexgrid. I
want user to enter only Date in that. So add DTPicker in that form. In
MSFlexgrid_Entercell event I am moving the DTPicker control to the
selected cell. The DTPicker control seems to move to the selected
location but not appear on the top! I set the zorder to 0 for DTPicker
but didn't work! Any one can me on this?

Thanks in advanced.
Vishal.
