Permissions access problem

[sweta87]

Hi Everyone,
i have created a role page in which i can create roles and whatever roles i have created is stored in database and a gridview. In that gridview an edit button column is there. When i am clicking the edit button another page known as permission page of the respective role. The permission page contains a grid view with ID, Pages, Add, view , delete columns and a button save. When i check the checkboes and click the save button in database Y is stored for checked checkboxes otherwise N. Now my problem is how my different aspx pages can be viewed, edited, according to my checkboxes status and how will i provide these permissions to my ad users.
Please help me to resolve this issue and give some example similar to my design if possible.
