DAL(Data Access Layer)

Question

Hii,

 

I am very new to ASP.NET. I followed the instructions given here https://msdn.microsoft.com/en-us/library/aa581778.aspx

 

I was able to create Typed data sets and table Adapter, but when I moved to the next step of displaying the information it shows multiple errors in the .cs file. Th errors are highlighted in the ss below. Any help would be appreciated.
