问题 The style for TextBlock (below) has no effect on the DataTemplate's TextBlock. If I change TextBlock to TextBox in both the style and template, the style applies as I would expect.

问题 I have a DataGrid in my Silverlight application that I would like to highlight an entire column when that column is sorted. It's similar in concept to this previous question: Silverlight DataGrid: Highlight an entire column. Any ideas? I've thought maybe attaching a behavior to the LayoutUpdated event and checking a cell to see if it's in a sorted column? 回答1: There are several issues that you have to get around to do what you want to do.

问题 Apologies if this has been asked before (I couldn't find the answer anywhere), but I have a WCF Service Application that I have created, and am trying to access via my Silverlight 4 app. I have added the service reference to the SilverLight App and am just trying to call one of the default pre existing methods on the service (GetData).
