    WindowDragCompletedEventArgs Class

    Contains data for the DragCompleted event.

    Namespace: DevExpress.Blazor

    Assembly: DevExpress.Blazor.v25.1.dll

    NuGet Package: DevExpress.Blazor

    #Declaration

    C#
    public class WindowDragCompletedEventArgs :
        EventArgs

    When the AllowDrag property is set to true, users can drag the Window. Handle the DragCompleted event to be notified when a user finishes dragging the window. The event argument’s End parameter returns the new window position.
