    Hi All, I added a C# class file to the C# project. I want to use the drop down control at runtime. I get an error when I write using System.Web.UI.WebControls; on top of the page. Can't we not use it?? How do I access any control at runtime in a class. Please let me know. Thanks.

    You're probably trying to use web controls in a project that has not imported the dll that contains them But that's a wild guess, seeing as you've not told us the error.

      Thanks. The error is The type or namespace name 'UI' does not exist in the class or namespace 'System.Web' (are you missing an assembly reference?)

        Yep - I'm right then. I'm not sure if you can use the web controls outside an ASP.NET project. They work by generating HTML in conjuction with the ASP.NET ISAPI filter, you realise that, right ? What's wrong with the Windows controls ?

          Thanks. Ok, now I just converted a code from VB.net class file to a C# class file. This works fine in VB.net. But it gave error here.

            OK, in that case your converter sucks. Just add the reference ( there's a references section on the top of the project, just right click and choose add reference, and look for System.Web, or whatever it is you need ) and you should be fine.

                  Cool! I have another Q, how do I create an ascx file for a user control. When I click on "Add user control", I get a xyz.cs file and not ascx file. This is the last Q...

                    There are two types of controls, one that has an ascx, and one that is code only. Make sure you're creating a 'web user control'. Christian I have several lifelong friends that are New Yorkers but I have always gravitated toward the weirdo's. - Richard Stringer

                      How do I add the ascx file? If I add the Usercontrol file, I get .cs extension file. I then change the extension to .ascx but I can't view the code. What am i doing wrong. This is really bugging.

                        Changing the extension would be a dumb thing to do. For starters, you need a .cs file in a user control as well. Like I said, if I right click on the project and choose 'Add Web User Control', I get an ascx. It's a custom control that doesn't have an ascx file. There is something very screwy about your setup, or how you're going about this.

                          You probably have a Windows Forms project when you want an ASP.NET project. Can you verify that? How to know: select the project name in the Solution Explorer. The property window should have only two items, project file and project folder. Project folder should be disabled. If project folder is a normal path, it's a Windows Forms project. If it is a URL (http://localhost....) it's an ASP.NET project. -- LuisR
