WindowActionsEventArgs

Namespace: PPJ.Runtime.Windows

Assembly: PPJ.Web.50 (5.0.0.0)

Carries a SAL window action, its target and parameters, and the handler's return value.

C#

public class WindowActionsEventArgs : EventArgs

VB.NET

Public Class WindowActionsEventArgs
    Inherits EventArgs

Assigning Return marks the action handled and records that an explicit return value was supplied. Setting Handled alone does not set a return value.

Example:

void OnWindowActions(object sender, PPJ.Runtime.Windows.WindowActionsEventArgs e)
{
    if (e.ActionType == PPJ.Runtime.Sys.SAM_Create)
        e.Return = 1;
}
