Remarks

The DataItem class identifies a data binding. A data item is mapped to a particular data source member when creating the instance of the DataItem descendant and can be assigned to a dashboard item. As a result, this binds the dashboard item to the data member.

This class also provides format settings for date-time and numeric values accessed via the DataItem.DateTimeFormat and DataItem.NumericFormat properties.

The DataItem class derives the Measure and Dimension classes for binding to quantitative and non-quantitative data respectively. These classes allow you to enable data shaping and configure summary calculation, depending on the binding type.

DataItem serves as the base class for the following descendants:

• Measure
• Dimension
