Description
Gets or sets the fields in the detail dataset that are used to establish a master-detail relationship with this dataset.
Use the DetailFields property value to specify a semicolon-separated list of the detail dataset field names used to establish a master-detail relationship with this dataset.
The DetailFields property is useful only for parameter-based master-detail setup. For range-based setup, the indexed fields are used as the detail field list. When DetailFields is not specified explicitly, the field names matching a query in the parameter names will be used as DetailFields value.
DetailFields are used only to assign specified field values when a new record is inserted into a detail dataset. The mechanism used to filter the detail dataset records does not use DetailFields.
