Recently I came across this awesome tool that I wish I was aware of it before. In some cases you have a list that defines fields your custom application uses for it’s own processing and you don’t necesarily want to expose those to NewItem.aspx or any other similar forms your user interacts.
In this scenario I used to Unghost the page with SharerPoint Designer and make all the necessary configuration manually. Turns out, there is an object model property that allows you to disable fields for selected views on any sharepoint list. Source code is also provided so you can check it out and see howthey did it
