any useful resources?

I have generated code using netTiers. Everything works fine, but I want to do some modifications.Eg: I have a \[code\]column[dataType varchar]\[/code\] (in a table) to store imageURL. For the same netTiers generates a \[code\]TextBox\[/code\]. I want to replace the \[code\]TextBox\[/code\] with a \[code\]FileUpload\[/code\], save the image in a folder and insert the URL into the DB.The problem I am facing here is that I have no clue how netTiers is passing the data. Where is the insert query? They have nothing in the button click also :O . I tried searching the button's \[code\]ID\[/code\] in the entire solution, but there was not a single occurance .Can you guys please point me to a good article or any useful resource? I am trying to get a grip at it but it seems it's gonna take some time.
