How do you appropriately setup a plugin data source to allow for null values (in .NET - C# preferred)?
I'm currently setting up a field using:
field.Type_2 = esriFieldType.esriFieldTypeSingle; field.IsNullable_2 = true; field.Name_2 = "Foo";
Then, later, during the cursor's QueryValues call, I'm trying to set a null value via:
// Given: public int QueryValues(IRowBuffer row) row.Value[i] = null;
However, the value always maps through as 0, not null. How do you properly setup the data source in a plugin data source to allow for a null value?
