Custom Control - Collection Property - ASP.NET

Hey gang. I am taking the task of trying to learn how to write custom web controls. I have started with inheriting from the VS 2005 default which is UserControl. I am implementing collection and just basic properties in my control and they are compiling and running so far but when I try and view the page in the designer I get such things like: Error Creating Control Type 'System.Web.UI.UserControl' does not have a public property named Columns But when I run the page everything is okay.

    Default Custom Control - Collection Property

    Hey gang. I am taking the task of trying to learn how to write custom web
    controls.

    I have started with inheriting from the VS 2005 default which is UserControl.

    I am implementing collection and just basic properties in my control and
    they are compiling and running so far but when I try and view the page in the
    designer I get such things like:

    Error Creating Control
    Type 'System.Web.UI.UserControl' does not have a public property named Columns

    But when I run the page everything is okay. Could someone please describe to
    me why this is occuring?

    Also most examples I see using Collections uses Control or WebControl. Is
    there any disadvantage to using UserControl and does this cripple my use of
    properties in any way? I like the design-time support for the UserControl.

    Any help would be greatly appreciated.

    Thanks and take care.

    Prefer to work with WebControl.

    UserControl, I say, are quick and (may not be) dirty solution to a complex
    control.

    UserControl needs to be compiled by the VS.Net (using ASP.Net) for
    design-time support. At times, it may go out-of-sync.
    Also, one needs to always have the ascx alongwith the compiled binary...
    that's why, prefer WebControl.
