By default, the AutoSave property is 1000 ms, which indicates that the changes are automatically saved after 1 second. If AutoSave property is 0, the control's save the data on closing. The Save method saves the control's data, while the HostDirty property is True. If no change occurs since last save, nothing will be saved.

Once the HostDirty property is set, the Save will be performed if:

• calling programmatically the Save method
• after elapsed time, if the AutoSave property is positive
• once the user closes the form/dialog

Once the Save method is performed, the HostDirty property is set on False.
