C# Programming :: Deriving from forms


	Deriving from forms In the base form you must change the button's "Modifiers" attribute to "Public" (or "Protected", etc). Since it defaults to "Private", you cannot change it in the derived class. Hence the UI Designer blocks you from changing it there too.

The base form defines the default location for the control, and this can only be changed in the base form. But your derived form certainly can rearrange things at run-time if you like. If you have a good way of programmatically determining where you want the button, then moving it in the constructor or the Load event handler may be a good alternative for you.

Sigh...yes, I'm a goof. Please ignore the above. Obviously you can have the derived class initialize the control in a new place, as long as the access to the control is set correctly. -----------------------------------------------Reply----------------------------------------------- I believe this is incorrect: if you change the "Modifiers" on the control, in the base form, then the designer will let you move it in the derived form. Then, you can change other attributes of the control in the derived form as well (e.g. Enabled, etc).

Pete -----------------------------------------------Reply----------------------------------------------- If I had a nickel for every incorrect post I made, I could buy a new computer. I happened to know the answer to this question because I spent quite a few minutes trying to figure out how to do this in a previous project. BTW, our series reinforces something I thought I had learned: wait a few moments before replying to a post :-) "Peter Duniho" <NpOeStPe@nnowslpianmk.com> wrote in message news:op.ttgp1xi68jd0ej@petes-computer.local... - Hide quoted text - > On Tue, 05 Jun 2007 11:59:47 -0700, Fred Mellender > <nospamPlease_fr@frontiernet.net> wrote: >> I believe this is incorrect > I believe I beat you to pointing that out. :) > Yes, my post was wrong...trying to do too many things at once is not good > for thinking things through before posting, apparently. :) Sorry for the > confusion. > Pete That worked. thanks.
