For a crosstab column (field instance), returns the name of the design-time field from which it was generated.
Field.XTabColDef
Read-only at run time. Unavailable at design time. Type: String. Property applies to Field object in TDataLite control. Not available in TData control.
This property applies to crosstab mode. For a crosstab column (field instance), it returns the name of the design-time field from which it was generated.
In crosstab mode, a single TData field defined at design time can generate multiple fields (crosstab columns) at run time. Such fields are called crosstab fields. This property allows to find out at run time, whether a field is a crosstab column (if it is not, the property returns empty string) and which crosstab field it belongs to.
