VS Designer code change

Julien Lefebvre

Hello all,
When we add a new component in default.aspx in the designer mode, it
automitically adds a line declairing the component in the codebehind. We dont
want the declaration of this component in the code behind because we inherit
from a base class which already contain this declaration of the component.
For example, we need a "TopMenu" component in all pages so we declared it in
the Base Class. The base class will fill this menu...
My issue is that when I use the Design mode, VS adds the component
declarations in my code behind. So I have the declaration twice (code behind
& base class) and this two declaration makes conflict.
Do you have any idea to create a base class & use the design mode without
having this conflic?
Thanks.

Hi Julien,

Welcome to ASPNET newsgroup.
From your description, you've define a base page class for your asp.net web
site and other pages will derive their codebehind page class from that base
one. Also, you've defined an component object reference as member in the
base class. However, when you add such a component in the derived page's
design-view, you found the VS.NET IDE will always add a new reference
member variable in the derived class rather than associate the component
with the reference in base class, yes?

As for this problem, I'm afraid it is due to the existing limitation on
ASP.NET Web form's page inheritance. The current ASP.NET web page's
inheritance is just simple codebehind class's inheritance on language
layer. It is not the actual Visutal inheritance like the winform's form
inheritance. So when we add new components or controls in ASP.NET page's
design-view in VS.NET IDE, the IDE has no idea of the existing component or
contorl reference in parent codebehind page class, it'll always add
reference member in the derived page class's code.

In ASP.NET 2.0, the MasterPage feature provide the complete Webform Visual
Inheritance that can help us add components or controls in MasterPage.

How do I have a UITypeEditor tell the Designer that the component has changed?

by: Ken Dopierala Jr. | last post by:

Hi, When I change properties through the property window on my custom control and then move focus from that property cell VS.Net runs the GetDesignTimeHtml() method on my designer. When I implement a UITypeEditor, change the values, then close the editor nothing happens until I switch the HTML view (which shows the changes) and then switch back to design view which then shows the new stuff. I can get to my component through the...

Control inheritance spoiled by Form designer.

Hello! There is a file called Forms1.Designer.cs that is located below Form1.cs if we assume that we call the file that name. I wonder if it's allowed to change in the file Forms1.Designer.cs except InitializeComponent ? One more question is it really any point to change in the Forms1.Designer.cs ? I just wonder if it's enought in general to change only in the Form1.cs if we call the file that name ?
