that I got from the Wrox website for this book, I keep getting a run time error as the application keeps crashing on me. I get following runtime warning:
Warning 2 C:\BegASPNET\Chapter 14\App_Themes\Management\GridView.skin: ASP.NET runtime error: There is no build provider registered for the extension '.skin'. You can register one in the <compilation><buildProviders> section in machine.config or web.config. Make sure is has a BuildProviderAppliesToAttribute attribute which includes the value 'Web' or 'All'. C:\BegASPNET\Chapter 14\App_Themes\Management\GridView.skin 1 1 C:\BegASPNET\Chapter 14\

And I get the following runtime error
Server Error in '/Chapter 14' Application.
On page 560 of the book.

Does it really crash? And at run-time? Or do you just get a warning at design time in Visual Studio?

For the first issue, check out page 247.

For the second issue, check out page 246 / 247. In addition, check the last sentence of step 5 o page 560 and the code example that follow.

I was using your code because the VS environment was throwing an error message, I guess a warning, which has means that you will have a run time error if you try to run the program. So I was copying and pasting your code into my .skin file and unbeknownst to me Visual Studio was automatically putting an ID value in there as soon as I pasted your code from your .skin file to my .skin file. I removed the ID from the skin file and that fixed the problem.

>> I guess a warning, which has means that you will have a run time error if you try to run the program.

Nope; that shouldn't be the case. It should be a warning at design time only, and it should have no effect at runtime. Are you seeing something else?

>> Visual Studio was automatically putting an ID value in there as soon as I pasted

Yep; you find a warning about that on page 248...
