Deleting Persistent Field Components

Deleting a persistent field component is useful for accessing a subset of available columns in a table, and for defining your own persistent fields to replace a column in a table.

To remove one or more persistent field components for a dataset

  1. Select the field(s) to remove in the Fields editor list box.
  2. Press Del.
Note: You can also delete selected fields by invoking the context menu and choosing Delete.
Fields you remove are no longer available to the dataset and cannot be displayed by data-aware controls. You can always recreate a persistent field component that you delete by accident, but any changes previously made to its properties or events is lost. For more information, see Creating persistent fields
Note: If you remove all persistent field components for a dataset, the dataset reverts to using dynamic field components for every column in the underlying database table.
