DataWindow.Cancel Method |  |
Discard all information entered in this data window and close the window.
Namespace: VO
Assembly: VOGUIClasses (in VOGUIClasses.dll) Version: 2.21
SyntaxRemarks
The "cancel" operation is very clear and easily understood and might be profitably used on
data windows when they are created as MDI children (unconventional or not).
Note that a user might be unclear on exactly what transactions are discarded.
For example, if several records have been modified, the default implementation
of DataWindow:Cancel() discards changes only to the current record.
You might want to label the button or menu command something else or provide a more comprehensive implementation.
 Tip |
|---|
| DataWindow:Cancel() disconnects itself from the data server using DataServer:UnregisterClient() and tells the server that it can close itself if it has no other registered clients. Explicitly forcing the server to close from a window is not recommended, since this can create future problems. Modifications to the application can attach other clients to the server, and any one window should not disable other windows. |
