自定义被封装的工作流控件方法

自定义类TaskEventArgs继承EventArgs，如果onTaskChanged控件需要自定义方法，那么先定义该方法属性，DesignerSerializationVisibilityAttribute，BrowsableAttribute，CategoryAttribute，定义EventHandler<TaskEventArgs>类型的方法，具体代码如下：

TaskEventArgs.cs

using System;

using System.Collections.Generic;

using System.Text;

using System.Workflow.Activities;

using Microsoft.SharePoint.Workflow;

namespace wfACT

自定义方法:

public static DependencyProperty onTaskChanged_IsTaskCompleteEvent = DependencyProperty.Register("onTaskChanged_IsTaskComplete", typeof(System.EventHandler<wfACT.TaskEventArgs>), typeof(wfACT.TaskActivity));

[DesignerSerializationVisibilityAttribute(DesignerSerializationVisibility.Visible)]

[BrowsableAttribute(true)]

[CategoryAttribute("TaskChanged属性")]

public event EventHandler<TaskEventArgs> onTaskChanged_IsTaskComplete

{

{

{

base.RemoveHandler(onTaskChanged_IsTaskCompleteEvent, value);

}

}
