Unable to find Control in List



I'm trying to define the parameters of my data source using a stored procedure. My Stored Procedure Syntax is perfect and i'm happy with that, i've just got trouble with connecting my parameters to my controls. I have 19 Parameters, of which i've managed to connect 17 to controls within my ASP.Net form (some to text boxes, some to ddls etc...)

However, i'm trying to connect a particular parameter to a control, but when i drop down my list of controls it's not visible? The control is within a hidden panel so i've un-hidden it and it's still not there. I've even commented out the panel and tried that but i can't find this control! I just cant seem to get this control to appear in the list.

Has any one seen anything like this before at all?

If you need any more information please let me know. (for clarirty i've attached screen grab)

Cant find vsi file for CSS Friendly Control Adapters


Hi guys

This is driving me crazy... I cant find the .vsi file for installing the CSS Friendly Control Adapters Project. Does anyone know where I can get this?

The following link: http://www.asp.net/cssadapters/ only leads to the CodePlex wiki where I can download the dll and a partial solution. Essentially, I'm looking for the source code to implement the Menu adapter.

Any help is much appreciated!

Security Briefs: Access Control List Editing in .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.
