Overview

OLAP Component displays data from Salesforce Order table using ADO.NET Connector for Salesforce.

ShowValueFieldHeaders 

You can use the viewDefinition property to save and restore view definitions, as shown in the following example:

The PivotGrid control extends the FlexGrid control, so you can export it to any of
the formats supported by the extension modules provided with the FlexGrid. The
list of the supported formats includes .xlsx, .csv, and .pdf.

For example, clicking the button below creates an Excel file with two sheets: the current view and a transposed version of the current view.
