IDataReaderExtension.IsAggregateRow Property

Definition

Indicates whether the current row contains aggregate data.

public:
 property bool IsAggregateRow { bool get(); };
public bool IsAggregateRow { get; }
member this.IsAggregateRow : bool
Public ReadOnly Property IsAggregateRow As Boolean

Property Value

A value of true if the current row contains aggregate data; otherwise, false.

Remarks

The IsAggregateRow property enables you to supply specific, aggregation information about your result set to the report server. Take, for instance, the following result set:

City          State          Sales  
====================================  
Seattle       WA             150.65  
Seattle       (null)         150.65  
Tacoma        WA              75.54  
Tacoma        (null)          75.54  
(null)        WA             226.19  
Portland      OR             112.25  
Portland      (null)         112.25  
(null)        OR             112.25  
(null)        (null)         338.44  

Your result set should return false for IsAggregateRow anytime all fields in the row of a result set contain data. In the previous example, you would return true for IsAggregateRow anytime that columns in a row contain an aggregation field, such as in rows 2, 4, 5, 7, 8, and 9.
