Declaration
Property Value
Type | Default | Description |
---|---|---|
ModificationsHandlingMode | Confirmation | A ModificationsHandlingMode enumeration value that specifies the WinForms application behavior when a user modifies data and then changes the current object or closes the View. |
Remarks
To specify the ModificationsHandlingMode in your code, inherit the WinModificationsController and override the OnActivated method.
using DevExpress.ExpressApp.SystemModule;
using DevExpress.ExpressApp.Win.SystemModule;
// ...
public class MyWinModificationsController : WinModificationsController {
protected override void OnActivated() {
base.OnActivated();
if (View is ListView)
this.ModificationsHandlingMode = ModificationsHandlingMode.AutoCommit;
}
}
Note that a custom value should be assigned after the base class’ OnActivated method is called, as the default value is calculated by this method. Avoid changing the ModificationsHandlingMode by accessing the ModificationsController from a custom controller via the Frame.GetController<ControllerType> method. Your custom controller may be activated before the ModificationsController activation, and your customization will be ignored.
