Since I didn't actually do the work, and the person that did is no longer with the company, I'm not sure the specifics why we overrode the entire control template for the grid (I think it had to do with restyling some aspect of the control that you can only get to by replacing the template). According the dev's notes, the template was provided by Telerik for the 2012.Q1 release and he only modified the colors applied to various parts to fit our branding. The template did have references to the MetroTheme which no longer exists in 2013.Q1 so we had to change that to the Windows8Theme (the only changes we made to any of our styles, templates, etc.).
When we run the application, I can see that the grid is there because the vertical scroll bar will appear but nothing else is displayed. I verified that the problem is not due to the foreground and background colors being the same by changing the background of the parent control. There is literally NOTHING displayed.
We also make use of several other Telerik controls, including a couple with custom templates, and none of them are having any issues.
What has changed in the new version that has broken our apps? What should I be looking for/at to get the control working again?

Currently, your project is built with NoXaml binaries (used with our implicit-styling mechanism) and this is why you are not seeing the GridView. With Q1 2013 we started shipping only NuGet packages with NoXaml binaries. The idea behind this decision was the smaller size of those assemblies and the requests received from our clients. We will add packages with Xaml binaries for the next official release - Q2 2013.
If you prefer to continue using the Xaml binaries, you can download them under Your Account. In case you are interested in using NoXaml binaries and implicit styles, please check this help article for a reference on how to use them in your project.
