Remarks
Note
This member is not supported in Optimized, OLAP, and Server modes. Use ExpressionDataBinding/OlAPExpressionBinding instead.
By default, the unbound expression is calculated against each data source record, and then the resulting values are summarized. If necessary, you can calculate unbound field values on the visualization (or summary) level. You can also use a specified set of summary functions (such as Sum, Avg, etc.) to summarize data source records. The UnboundExpressionMode property allows you to specify the mode used to calculate unbound field values.
