It would be nice to have built-in support for a row details feature in the Grid similar to the Telerik Silverlight GridView. http://demos.telerik.com/silverlight/#GridView/RowDetails
You should really look at the ASP.Net version which provides a more complete result. Although I like the SL version, but the ASP is just more complete.
I second that. I could really use this feature.
Thanks for the proposal - our team will review your request and will discuss the possibility to include row details feature for the future versions of the Kendo UI Grid Widget.
