-
Open the expression editor for the List source field.
-
Write one of the following expressions:
New List(Of String) From {"Value1", "Value2", "Value3"}.ToListSource()New List(Of String) From {"Value1", "Value2", "Value3"}.ToListSource(){"v1", "v2", "v3"}.ToListSource(){"v1", "v2", "v3"}.ToListSource()
