Initializes a new instance of the Measure class, binds it to the specified data member and sets the summary type to the specified value.
public Measure( string dataMember, SummaryType summaryType )
Public Sub New( dataMember As String, summaryType As SummaryType )
The data member identifier passed via the dataMember parameter should consist of the data table name and the column name, dot separated. For instance, the Street Address column from the Customers table is identified as "Customers.Street Address".
If a data source has been specified in code, particular data fields can be custom objects. In this instance, the identifier is a chain of property names, like "Customers.City.Population".
Note that aliases specified in the Query Builder are not used in data member identifiers. Use actual column names instead.
