Hi

I am pretty sure it's something I have set on a control or something,
But I have now hit a brick wall trying to work it out. SO I hope
someone can shed some light on what settings is causing the Problem.

I have a panel that has controls on it, and I am trying to adjust the
panel height so that the non-active controls are not displayed.
However when I change the Pane.height the controls get all shifted and
display incorrectly.

Below code trying to work the problem shows a control.top on the panel
changing.
showmessage('Control Top Before Height
Adjusted:'+inttostr(bank_cat_000.Top));   // This display 24 as is the
top control on the panel. which is correct
Banks_Popup_Panel.Height:=200; // Now adjusting the height of panel to
crop the bottom section
application.processmessages;
showmessage('Control Top After Height
Adjusted:'+inttostr(bank_cat_000.Top)); // This now display -10   Why?

Unfortunately I cannot upload the whole application, the Panel has
components that are created at runtime, I can move the panel around
the form and all controls stay intact, but when I change the Panel
Height. everything gets messed up.

I am hoping that it is a setting with component creation rather than a
bug.

Hoping someone can help and help.

Controls on the panel are anchored or aligned?

Maybe you changed Panel.ChildSizing. Or simply check all non-default
properties in OI (they are red and bold).

Hi Blaazen,

It was the akLeft,akTop that had been removed.
Problem was in my routine that sets all controls Fonts,position  etc
before the application is made visible. For some reason I had adjusted
these ( must of been for some testing at some point, and forgot to
remove).

But all is good now

Thanks
