Please check the latest prerelease build.

2, how to filter with ( == null) or (!=null)

Here you are:

DataSource["DataFieldName"] == System.DBNull.Value

Thank you.

Thank you for suggestion. It is a really good idea.

Also checking may be done as follows:

IsNull(DataSource,"DataColumnName") == true

Thank you.
