Updated: October 2008
Specifies when a data source is updated when changes occur in the bound control.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
| Member name | Description | |
|---|---|---|
![]() | OnValidation | Data source is updated when the control property is validated, After validation, the value in the control property will also be re-formatted. |
![]() | OnPropertyChanged | Data source is updated whenever the value of the control property changes. |
![]() | Never | Data source is never updated and values entered into the control are not parsed, validated or re-formatted. |
When a control is bound to a data source using a Binding object, you can specify when an update to the data source will occur using the DataSourceUpdateMode enumeration.
When the update mode is Never, you can force the data source to be updated by using the WriteValue method.
Note: |
|---|
Even when the update mode is set to Never, the data source will be updated when the binding is first created, so that at least one update will always occur. |
