Greg,

>I am working through the Jump Start: Windows Forms Application - C# in VS 2003 and have a problem on Step 13 - Enhancing the DataGrids. The enhancement to the Orders DataGrid worked fine however the enhancement to the Order Detail DataGrid results in no change in appearance (headers, null display, size). I double checked the settings and can't find anything wrong. I'm certain I've missed something simple but as a newcommer to .NET I'm lost. Can someone give me a hint on to how to figure out why this isn't happening?

Hmmm...it's hard to tell from here what's going on. A quick run-through of the properties seems like they are set correctly. You may want to just drop a second DataGrid on the form and try it on that one. You can also check out the sample application which has this DataGrid set up properly.
