Name |
Description |
|
Specifies whether or not a dataset is open. | |
|
Contains any aggregate fields. | |
|
Determines when the OnCalcFields event is triggered and when lookup field values are calculated. | |
|
Determines how many record buffers are read in each block. | |
|
Indicates whether the first record in the dataset is active. | |
|
Specifies the current bookmark in the dataset. | |
|
Indicates whether the dataset permits write access to data. | |
|
Indicates the persistent TDataSetField object that owns a nested dataset. | |
|
Represents the data source of another dataset that supplies values to the dataset. | |
|
Indicates whether a dataset's underlying field components are generated dynamically when the dataset is opened. | |
|
Returns a pointer to the Dataset designer for the dataset. | |
|
Indicates whether a dataset is positioned at the last record. | |
|

|
Points to the list of field definitions for the dataset. | |
|
Lists the field components of a dataset. | |
|
Lists all non-aggregate field components of the dataset. | |
|
Provides access to the values for all fields in the active record for the dataset | |
|
Specifies the text of the current filter for a dataset. | |
|
Specifies whether or not filtering is active for a dataset. | |
|

|
Indicates whether or not moving to a different record is successful. | |
|
Indicates whether the dataset is unidirectional. | |
|
Indicates whether the active record is modified. | |
|
