Property Value

Type	Description
Int32	An integer which specifies the duration of the WinForms Alert and ASP.NET and Blazor notification (in milliseconds).

Remarks

A notification message window is closed when this duration time is up or when a user clicks the message.

This property has no effect in WinForms applications with Flyout or Toast notifications.

The default value is 3000. If the Duration is set to int.MaxValue, the notification does not close automatically.

• In Blazor applications: if the Duration is less than 0, the default value is used.
• In Winforms and ASP.NET applications: if the Duration is less than 0, the notification message is closed immediately.
