In the next section we will see how to implement declarative fine grain authorization via the LoginView control. Note Summary In this tutorial we looked at how to specify coarse and fine grain authorization rules based on the user s roles. Applying authorization rules on a user-by-user basis can grow into a bookkeeping nightmare. As an Administrator, you may edit and delete user accounts. Table 1: The Role Cache Cookie Configuration Options Let s configure our application to use non-persistent role cache cookies. Note that if there is more than one RoleGroup specified, the LoginView template renders the first RoleGroup that matches. Let s format the output of this BoundField so that just the date is displayed (instead of the date and time) rowupdating in gridview example.

This cookie is used in subsequent requests in the PostAuthenticateRequest, which is when the RolePrincipal object is created. Step 1: Defining Role-Based URL Authorization Rules As discussed in the User-Based Authorization tutorial, URL authorization offers a means to restrict access to a set of pages on a user-by-user or role-by-role basis. Introduction In the User-Based Authorization tutorial we saw how to use URL authorization to specify what users could visit a particular set of pages. The GridView control offers built-in editing and deleting support when the control is bound to a properly configured data source control, such as the SqlDataSource or ObjectDataSource rowupdating in gridview example. I encourage you to add some form of user confirmation to lessen the chance of an account being accidentally deleted. The second overload can be used to more efficiently page through the users since it returns just the precise subset of user accounts rather than all of them. config, log in as a user that is not in the Administrators role and then try to visit one of the protected pages.

UpdateUser(UserInfo); // Revert the grid s EditIndex to -1 and rebind the data UserGrid. Configure the LastLoginDate BoundField by setting its HeaderText to Last Login and its DataField to LastLoginDate. If a person in the Administrators role visits this page, we will show instructions on how to edit and delete users.
. NewEditIndex; BindUserGrid(); } protected void UserGrid_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e) { // Revert the grid s EditIndex to -1 and rebind the data UserGrid. Set the GridView s DataKeyNames property to UserName so that this information is available through the GridView s DataKeys collection. Let s update this page so that only users in the Supervisors and Administrators roles can edit a user s email address and comment, and only Administrators can delete a user account. This turns the CommandField into a TemplateField with an ItemTemplate and EditItemTemplate houses the Update and Cancel LinkButtons.

And if you log in as a user in the Administrators role you should see the Administrators role-specific message (see Figure 10). .
