Description |
|---|---|
dwcontrol |
A reference to the DataWindow control, DataStore, or child DataWindow in which you want to reselect a row |
row |
A value identifying the row to reselect |
Returns 1 if it is successful and –1 if the row cannot be reselected (for example, the DataWindow object cannot be updated or the row was deleted by another user).
If any argument’s value is null, in PowerBuilder and JavaScript the method returns null.
ReselectRow is supported for SQLSelect DataWindows. Use ReselectRow to discard values the user changed and replace them with values from the database after an update fails (due to a concurrent access error, for example).
About timestamp support
Timestamp support is not available in all DBMSs. For information
on timestamp columns, see the documentation for your DBMS.
This statement reselects row 5 in the DataWindow control dw_emp:
dw_emp.ReselectRow(5)
This statement reselects the clicked row if the update is not successful:
IF dw_emp.Update( ) < 0 THEN
dw_emp.ReselectRow(dw_emp.GetClickedRow())
END IF
