Namespace: DevExpress.XtraSplashScreen

Assembly: DevExpress.XtraEditors.v24.1.dll

NuGet Package: DevExpress.Win.Navigation

Declaration

public static SplashScreenManager Default { get; protected set; }

Property Value

Type Description
SplashScreenManager

A SplashScreenManager that is the default splash screen manager.

Remarks

The instance returned by the Default property allows you to interact with the currently opened splash form.

Only use the Default property in the following cases:

In all other cases, the Default property returns null. Do not invoke methods on the Default object to open splash forms.

To interact with any splash form, use the SplashScreenManager.SendCommand method. To set a Wait Form’s caption and description, use the SplashScreenManager.SetWaitFormCaption and SplashScreenManager.SetWaitFormDescription methods.

Example

In this example a custom Progress Bar Control is added to a Splash Screen. The example shows how to update this Progress Bar Control dynamically by sending commands from a Splash Screen Manager.Splash Screens are displayed by a Splash Screen Manager in a separate thread. Interaction with Splash Screens can be performed via the command mechanism. You send a command via the SplashScreenManager.SendCommand method and process this command by overriding the SplashScreen.ProcessCommand method. In the example, custom commands are sent to the Splash Screen to advance the progress of the Splash Screen's Progress Bar Control.

Example

A Wait Form is displayed by a Splash Screen Manager in a separate thread. To dynamically change labels within the Wait Form, while it is being displayed, use the SplashScreenManager.SetWaitFormCaption and SetWaitFormDescription methods.

            //The Wait Form is opened in a separate thread. To change its Description, use the SetWaitFormDescription method.
            for (int i = 1; i <= 100; i++) {

            //Close Wait Form
            SplashScreenManager.CloseForm(false);
        }
    }
