Hi All,
Maybe a strange problem  I have a window to which I programatically add controls, one underneath the other vertically. There is an unknown number of such controls which I need to add, can be 100+ for example. When I do this the window vertical scroll bar does not size sufficiently to allow me to scroll to the bottom of the controls that I have added. The scrollbar only appears if I size the window to less than the design height.
How do I force the scroll bar to appear so that it reflects the total true height of all the controls I have added to the form?
Thanks |

Hi JP
funny
2 questions the same day with basically the same answer...
The usual way to do this is to add your control into a supercontrol, increase its size, and it will provide the scrollbars when it is bigger than the window itself. And don't change the window size.
Best regards |

lol! Yes, that is a coincidence indeed!
I have not used supercontrols before. How does one go about doing what you suggest? |

I have created a blank supercontrol and am adding my controls to it. But the scrollbars do not appear. I think I might be missing some settings for the window and/or the supercontrol. Any suggestions where to look? |

Fabrice,
OK, I found the SuperControl.UsefulHeight property and that is the one I needed to increase beyond the height of the control itself. Doing that and the vertical scrollbar appeared as required.
Thanks |

AFAIK, Control templates do not provide an automatic scrollbar when the template is bigger than the screen, while supercontrols do. Which is why they are used in that case.
