【应用场景】

运行时，通过插件，禁用其它的插件。

【案例演示】

采购订单，表单插件，B插件会在界面上显示消息，通过A插件禁用B插件。

【实现步骤】

<1>编写表单插件DisablePlugInTestFormPlugIn，用于禁用插件测试，该插件会在单据打开时输出一个信息，代码如下。

using Kingdee.BOS.Core.Bill.PlugIn;
using Kingdee.BOS.Core.DynamicForm.PlugIn;
using Kingdee.BOS.Core.DynamicForm.PlugIn.Args;
using Kingdee.BOS.Core.Metadata.FormElement;
using Kingdee.BOS.Util;
using System;
using System.ComponentModel;
using System.Linq;
using System.Reflection;
namespace Jac.XkDemo.BOS.Business.PlugIn
{
    
    /// <summary>
    /// 【表单插件】禁用插件测试
    /// </summary>
    [Description("【表单插件】禁用插件测试"), HotUpdate]
    public class DisablePlugInTestFormPlugIn : AbstractDynamicFormPlugIn
    {
        public override void AfterBindData(EventArgs e)
        {
            base.AfterBindData(e);
            this.View.ShowMessage("哈哈哈！！！");
        }
    }
}

<2>编写Python插件，用于禁用插件测试，该插件会在单据打开时输出一个信息，代码如下。

# 【Python】【表单插件】禁用插件测试
def AfterBindData(e):
    this.View.ShowMessage("嘿嘿嘿！！！")

<3>编写表单插件DisablePlugInFormPlugIn，用于禁用插件DisablePlugInFormPlugIn和Python插件，代码如下。

using Kingdee.BOS.Core.Bill.PlugIn;
using Kingdee.BOS.Core.DynamicForm.PlugIn;
using Kingdee.BOS.Core.DynamicForm.PlugIn.Args;
using Kingdee.BOS.Core.Metadata.FormElement;

            RemovePlugIn();
        }

        {
            base.OnSetBusinessInfo(e);
            //RemovePlugIn();
        }
        public override void OnInitialize(InitializeEventArgs e)
        {
            base.OnInitialize(e);
            //RemovePlugIn();
        }
        public override void OnLoad(EventArgs e)
        {
            base.OnLoad(e);
            //RemovePlugIn();
        }
        public override void AfterBindData(EventArgs e)
        {

            //logs.AddRange(viewPlugInProxy.PlugIns.Select(plugIn => plugIn.GetType().FullName));
            //var msg = string.Join("\r\n", logs);
            //this.View.ShowMessage(msg);

}

<4>拷贝插件组件到应用站点的WebSite\Bin目录下，重启IIS。

<5>BOSIDE扩展采购订单，注册表单插件和Python插件，保存元数据，开发完毕。

【功能验证】

<1>登录业务站点，打开采购订单，界面上并不会出现提示信息，说明禁用插件的功能已生效。
