my answer from Dynamic column binding in Xaml

I've used an approach that follows the pattern of this pseudocode

columns = New DynamicTypeColumnList()
columns.Add(New DynamicTypeColumn("Name", GetType(String)))
dynamicType = DynamicTypeHelper.GetDynamicType(columns)

DynamicTypeHelper.GetDynamicType() generates a type with simple properties. See this post for the details on how to generate such a type

Then to actually use the type, do something like this

Dim rows as List(Of DynamicItem)
Dim row As DynamicItem = CType(Activator.CreateInstance(dynamicType), DynamicItem)
row("Name") = "Foo"
rows.Add(row)
dataGrid.DataContext = rows
