I don't know what this is called in SL, but I would like to replicate this functionality. If you go to this site: http://www.mscui.com/PatientJourneyDemonstrator/PrimaryCareAdmin.htm and click on the "Show Details" button located on the top, right-hand corder of the screen. When you click on this, there should be a "Scene Details" button-like feature on the right side. When you click on this, this is what I would like to implement. Can someone direct me please? Either to an online article, etc...
Although I don't know the specifics of the implementation, as far as I can guess, this is done by having a second Grid that follows the Grid for the page. Then, simply change the visiblity on the "guide" grid when the button toggles.
I believe that is simple, although it'll require you to work to figure out the positioning of the underlying page - but it's more flexible. With Blend it'll be easy.
Alternatively you could have a ton of additional UI elements on the page next to their respective controls, and either Tag or name them in a way that you can iterate over them to control visibility and interaction.
I'm not precisely sure what feature of the site you'r referring to (I'm blind so the description doesn't make much sense to me). However, two useful links - some of the MSCUI source code is available on Codeplex http://mscui.codeplex.com. Also, the Silverlight developer/designer on this project created Blacklight http://blacklight.codeplex.com which includes visual assets to use with Silverlight.
I think you're talking about a the grey overlay with a modal window on top. I think the best way to do that in Silverlight 3 is with the ChildWindow control.
