Hi again,

you can still go ahead withe the showpopup - you just have to change the popup properties:

eg if your calendar controls are on frmCalendar and your textbox is txtCandar then this will show the popup form directly below your textbox:

frmCaendar CalendarPopUp = new frmCalendar();

CalendarPopUp.Width = txtCalendar.Width; //optional setting that one

CalendarPopUp.ShowPopUp(txtCalendar, DialogAlignment.Below);

Currently what is your Calendar Controller - a UserControl?

if so you can easily convert it to a form by editing this line of code at the top of the CS file:

partial class UserControl1 : UserControl

to read

public
