Property Value
Type | Default | Description |
---|---|---|
String | null |
A String value that specifies the calculated field's data member. |
Remarks
The DataMember property should be specified only for DashboardSqlDataSource and DashboardEFDataSource. The SQL and EF Data Sources can contain multiple queries and the DataMember property of a calculated field determines to what query this field belongs.
The following example shows how to specify DataMember for calculatedFieldNotWorking
:
CalculatedField calculatedFieldNotWorking = new CalculatedField {
DataMember = "DashboardSqlDataSourceQueryWithJoin",
Name = "Calculated Field",
Expression = "[FirstName]",
DataType = CalculatedFieldType.String
};
