I have a question. I click on build, build solution i get a list of errors in the Error List. The error is: The name 'TextBoxRes' does not exist in the current context. Why is this happening? I checked the properties for the textboxes and the names are spelled right. I debugged the program and it runs fine. Why am I getting these errors for? Is there a way to fix them?

That usually means you are referencing the object out of scope.

What I did was I have to start over with the project. I started a new project and I named it something else. Then I just added the forms from another project to the new one. Did that start the errors?

Richard C Bishop 24-Sep-13 16:29pm

Probably, those controls won't exist in the designer of the project.

Computer Wiz99 24-Sep-13 16:31pm

Ok. So I will have to delete the current ones and add them again?

Richard C Bishop 24-Sep-13 16:32pm

Just try one and see if that fixes one. If it does, you will know what was the issue.

Computer Wiz99 24-Sep-13 16:33pm

Ok. Thanks. I will try that. Have to sign off now but I will let you know.

Ok. I tried changing one and the same error comes up. Like I said before the app debugs fine. It works when I view it in the browser and when I debug it. When I build the solution is when I get the errors. I also cleaned the solution and the errors went away until I build it or rebuild it again.

Solution 1

Your code refers to a couple of controls that are not available. For example your page SchoolReports.aspx has a code behind file SchoolReports.aspx.cs which refers to a ButtonPrint control.

The error (the first one of the list) tells you that the button ButtonPrint does not exist on the page SchoolReports.aspx.

Ok. I solved this myself. Here is the steps I did.

SQL

1. Run at server

To access the HTML element as a variable in the C# code, the following value must be placed in the HTML element tag in the aspx file:

runat="server"

Some objects in the Toolbox in the Visual Studio IDE do not automatically include this value when added to the page.

CSS

2. Regenerate the auto-generated C# file:

    In the Solution Explorer, under the aspx file there is another file *.aspx.cs. Right-click on the parent aspx file. In the pop-up menu, select Convert to Web Application. Click on Build, Build Solution. All the errors are gone. 

Now the element should be accessible in the C# code file.
