Security Briefs: Access Control List Editing in .NET

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net

Access control lists (ACLs) can be complex beasts, and user interfaces for editing them are incredibly tricky to implement properly. That's why I was really excited when Windows® 2000 shipped with a programmable ACL editor, shown in Figure 1.

Gridview with a dropdown list for editing


Hello. I am working through Scott Mitchell's ASP.Net in 24 hours book. I am finishing the photo album project.

I have a GridView that retrieves a list of uploaded photo rows for the logged-in user.
The GridView is for editing and deleting rows.

The photo Category field in the Gridview is a dropdown list. The text entry field was deleted after converting this field to a Template.

Like the uploaded photos, these Categories are user-specific. They are created in another web page.

Users also have the option to select "none" for the category when they upload an image.

For the GridView:  The Category ID field's ItemTemplate and EditItemTemplate both have a " - None - " choice added to them.

I am getting this error:

'pictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value


Note: The ID for the ItemTemplate for that dropdown list is the ID listed above in the error: "pictureReadOnlyCategories".


Am I missing some step in this process of changing a GridViews text field to a dropdown that can be used for editing? I went through the book's instructions three times.

Here is my code for the dropdown list and a screenshot of the Design

Security Briefs: Cryptographic Agility


Even if you use only the most secure algorithms and the longest key lengths, there's no guarantee that the code you write today will remain secure. A better alternative is to plan for agility from the beginning. Rather than hard-coding specific cryptographic algorithms into your code, use one of the crypto-agility features built into the Microsoft .NET Framework. This article shows you how.
