Read the article to blog Park is not all are masters, there are some beginners, this article is mainly for beginners, not deep contact with permissions to provide a reference.
We used to have a few buttons on the page, these buttons control authority, are doing very skilled
for example btnAdd the Add button, btnEdit Edit button, btnDelete delete button, this

"addStudent" permission correspondence -> Available Properties "frmStudentManager.btnAdd" button
"EditStudent" permission correspondence -> Available Properties "frmStudentManager.btnEdit" button
"DeleteStudent" permission correspondence -> "frmStudentManager .btnDelete "button available properties of

we can set these permissions correspond relationship:
"ViewStudentRealName" the proper permission -> list "RealName name field is visible"
"ViewStudentCode" permission correspondence -> list "Code number field is visible"
"ViewStudentAge" permission correspondence -> list "Age age field is visible"
"ViewStudentSex" permission correspondence -> list "sex gender field is visible"
just a few more rights, some rights are the corresponding button of the available properties, some of the corresponding column visible property only.

Often encountered in the past few years, such a question, a good mood today to write articles for your reference reference to it in the future may come in handy.
As for all the tables in the database automatically controls all fields, etc., that is another problem areas,
