I would try to avoid adding handlers to each item Jamie,

I'm in the same situation--I want events to get through to the DataGrid so that the user can perform sorts and the like (I don't need editing), so I don't want to just plaster a Canvas over the top of the grid. Also, has anyone played with the new agDataGrid to see if it deals with Drag and Drop any easier?

Expand Resources node. You will find system.windows.controls.data.g.resources in the Disassembler you will see Generic.xaml. that is how I got it Open the system.windows.controls.data.dll in reflector.

The XAML Parser in the IDE I was using was hiccuping on a stray angled double quote, not "(Color)". You’re right, sorry!

Editing ControlTemplates to do deep structural changes to the layout properties of Silverlight/WPF's box model architecture is a significant wart on the overall design of Microsoft's GUI toolkit. Layout has literally zero role in control behavior, and so it should be possible to do CSS-style deep, structural, tag pattern-matching changes to layout. I commented to Ashish Shetty that this is probably what costs me the most amount of time and disrupts my workflow more than anything else. It is a blatant violation of the Open-Closed Principle in Object-Oriented Analysis. See my comments that I made today here: http://nerddawg.blogspot.com/2008/06/beta-2-of-silverlight-2-has-just.html I don’t think I will ever like changing styles just to alter layout.

For one, your blog software has this "feature" where it converts vertical double quotes into angled double quotes. This feature makes it impossible to directly copy and paste code into Visual Studio C# or XAML files. And Storyboard.TargetProperty=”(Color)” should just say Storyboard.TargetProperty="Color".

Thanks for your help, Lee! I don't quite understand why it is so difficult to style elements compared with JavaScript UI frameworks that wrap HTML/CSS. For me, this seems like my biggest pain point with Silverlight and WPF. Simple styling that would take me seconds or minutes in HTML/CSS takes me hours to do in Silverlight and WPF, because I have to figure out where the Content I want to Style actually is within the ControlTemplate. Not only that, but in order to diddle just one field in one element, I need to replace the whole visual tree. I read WPF Architect Adam Nathan's opinion on how WPF Styles are better than Cascading Style Sheets, and I personally feel it is Not Invented Here Syndrome more than anything else. Nice.
