Designer Support when Inheriting from a Base Page Class

by: thechaosengine | last post by:

Upgrade To 2003: Cannot Load Web Forms Designer; Using Page Descendent

by: L Scott | last post by:

I've created a page ancestry (framework) for our application so that all pages in our app would have the same look and feel. To do this, I created several user controls (header, footer, menu, etc.) and then a C# class which inherits from System.Web.UI.Page. In the OnInit() method of this class, I dynamically load these user controls using the 'this.Controls.AddAt()' method (as well as call the base.OnInit() method to load the objects from...

The file could not be loaded into the Web Forms designer

by: crusell | last post by:

I'm having some problem with my Visual Studio.NET 2003 (.NET 1.1 SP1) install. I am unable to use the web forms designer with any aspx file whose form class inherits from a base class.

The class exists, is included in the project and compiles just fine. If I replace the base...

Designer doesn't work after overriding base class

by: dusanv | last post by:

Hi, I have a class (say O1) that overrides System::Windows::Forms::UserControl and then another one that overrides O1 (call it O2). O2 used to work with the Designer as it was inheriting directly from UserControl (and was created using the wizard) but since I inserted O1 into inheritance tree (without resx, straight override) I get the error pasted at the bottom when trying to open O2 in Designer. I deleted the NCB file to no avail....

The easy way to turn off automatic updates for Windows 10/11
