DataLink.Declaration
procedure LinkActive(Value: Boolean); virtualArguments
Value | True when the dataset is open. |
Description
LinkActive is a procedure which updates the control when the state
of its DataLink is changing. Value contains
False when the dataset for
the DataLink will be closed. The state change causes updates to other control
properties like SelectedRows which tracks the selected rows in the linked
dataset. LinkActive calls RemoveAutomaticColumns to remove automatic columns
added to the control when the DataLink became active. The LayoutChanged
method is called to refresh the control after updates to the Columns property.
No actions are performed in the method when Value contains True.
