Use this property to store content into the data table before analysis. The data that will be collected can either be created from an Expression, it can be come from a get/post request from another page, or it can be a static value. The difference between this and the Add Column XML property is that this process occurs before any analysis is completed, versus after.
Example:
<ExtraPreData>
<Data>
<ColumnName>Event Start</ColumnName>
<ColumnType>System.String</ColumnType>
<PageRequest>StartDateNew</PageRequest>
</Data>
<Data>…</Data>
</ExtraPreData>
