But when I try to add columns using Blend, I get a "object reference not set to an instance of an object" error.  If I add the column directly in XAML, the error moves to the column.</p> <p>Here is more detail from VS:</p><span lang="undefined"><p align="left" dir="ltr">Object reference not set to an instance of an object.</p><p align="left" dir="ltr">at Intersoft.Client.UI.Data.UXGridViewBoundColumn.–() at Intersoft.Client.UI.Data.UXGridViewColumn.(UXGridViewCell cell, Object dataItem) at Intersoft.Client.UI.Data.UXGridView."(Boolean isCellEdited, UXGridViewColumn column, UXGridViewRowBase row, UXGridViewCell cell) at Intersoft.Client.UI.Data.UXGridView.(UXGridViewNewRow row, UXGridViewColumn column) at Intersoft.Client.UI.Data.UXGridView.(UXGridViewColumn insertedColumn) at ..InsertItem(Int32 columnIndex, UXGridViewColumn column) at System.Collections.ObjectModel.Collection`1.Add(T item)</p></span>
