You may be too far into your current project to consider this, but using MultiView and View controls usually allows you do make DotNetNuke "act the way you want". By design DotNetNuke interprets requests for it's pages using a logic that allows it to do things like inject the proper skin and handle security. As developers we sometimes run into situations where it "wont act the way we would like it to".

Using the View controls allows you to put the criteria on one panel, Show the data list on another panel, have the click on the data list show details on another control that was invisible until you made a selection, and have a back button for the user to click (use the Wizard control if you have a lot of steps to keep track of).

If you come from the old classic asp days like me you're used to jumping from page to page. DotNetNuke doesn't really like that too much. Using View controls can usually solve all your problems. You can put a massive amount of functinality on the page and you actually end up with a lot less code.

Is there a reason you are jumping to another page to display the details? Is it because you want everything else off the page and you want more room?

If so I would use NavigateURL: How to make a link (VB &C#) . Some people don't like this because it causes DotNetNuke to use the "Admin panel" (all the other modules on the page disappear) when you navigate to another user control using this method. However, I use this a lot because I want all the other things to go away and for the user to concentrate on the page I am displaying to them. And for me the back button usually works in this case.
