I am a non-developer trying to mock up applications using Telerik Sliverlight controls in Microsoft Expression Blend 3.
In the Expression Blend 3 assets, under Controls > Telerik RadControls for Silverlight Q1 2010 > GridView, I added a RadGridView element to the screen. The grid has columns like ContactName and Address - how do I customize these columns? With a standard DataGrid, I am able to drag and drop my custom data collection into the DataGrid and the DataGrid displays the custom data. The RadGridView won't let me do that.
