[CE5 C#] DimStyleProp Alignment Problem

In VBA, to set the Alignment mode in DimensionStyle from "View" to "True", we use

DimensionStyle.Alignment = MsdDimAlignment.True

When we are in .NET API, we use:

DimensionStyle.SetIntegerProp(2, DimStyleProp.General_Alignment_INTEGER);

and apply it to DimensionCreateData.

However, the dimension element is not working as true alignment. What did I miss?
