Ways to Show a Confirmation Dialog

This topic describes approaches to showing a confirmation dialog. You can show a simple confirmation message or a confirmation dialog with additional fields.

This topic contains the following sections.

Tip

If you want to show a simple text notification, refer to the following topics:

Expanded Using the ConfirmationMessage Property

You can change a default confirmation message for built-in or custom Actions using the ActionBase.ConfirmationMessage property in code or IModelAction.ConfirmationMessage in the Model Editor.

For example, change the confirmation message for the Delete Action as demonstrated in the following code snippet.

To see the result, click the Delete Action.

Expanded Using a New Detail View

In this section, the confirmation form is a pop-up window with the DetailView of the ConfirmationWindowParameters object, which contains a confirmation message, the accept and cancel buttons, and will be invoked in an Action's Execute event.

For example, the confirmation message, the Close and OK buttons are placed on the confirmation form. Create a class with form layout properties, such as confirmation message text and visibility of elements. Decorate this class with the DomainComponentAttribute to register it in the Types Info Subsystem.

The confirmation message will be shown in a pop-up window on an Action click. Create a new ViewController and PopupWindowShowAction in its constructor. In the Action's CustomizePopupWindowParams event, create an IObjectSpace object, a new ConfirmationWindowParameters class instance, and the DetailView for this object. Set the ConfirmationWindowParameters object's properties to the required values and the CustomizePopupWindowParamsEventArgs.View parameter to the newly created DetailView to show it in the pop-up window.

The following images demonstrate this confirmation window.

Expanded Using the Messaging Class' Methods

In WinForms applications, the confirmation window can be shown using the Messaging class' methods. This class provides you with the main features to display the confirmation message with the standard set of dialog buttons (see MessageBoxButtons).

Add the following Controller, which demonstrates a simple example of using this approach, to your WinForms Module project.

The image below demonstrates this implementation result.
