【应用场景】

变更项新增一个标记完成时间，但是标记完成有界面交互，没办法准确捕获点击事件。

因此需要通过控件绑定值事件（二开案例.单据插件.事件.BeforeControlDataBinder (kingdee.com)），在变更项数据重新绑定时，进行数据对齐。

【案例演示】

【实现步骤】

<1>编写表单插件；拷贝插件组件到应用站点的WebSite\Bin目录下，重启IIS。

你可能需要引用以下组件：

编写代码如下：

using Kingdee.BOS;
using Kingdee.BOS.App.Core.Utils;
using Kingdee.BOS.Core.DynamicForm.PlugIn.Args;
using Kingdee.BOS.Orm.DataEntity;
using Kingdee.K3.PLM.Business.PlugIn;
using Kingdee.K3.PLM.Common.Core.BOSBridge;
using Kingdee.K3.PLM.Common.Core.Utility;
using System;
using System.Collections.Generic;

namespace ISV.EcnEntity.Common.BusinessEntity
{
    public class EcnBillDemoPlugin : AbstractPLMBillPlugIn
    {
        public override void BeforeControlDataBinder(BeforeControlDataBinder e)
        {
            base.BeforeControlDataBinder(e);
            if (e.Control.Key == "FChangeObjectEntity")
            {
                var ChangeObjectEntity = e.RowData.GetDynamicObjectItemValue<DynamicObjectCollection>("ChangeObjectEntity");
                if (ChangeObjectEntity != null)
                {
                    var dataChanged = this.View.Model.DataChanged;
                    var finishedTime = DateTime.Now;
                    var finishedItems = new List<long>();
                    var cancelItems = new List<long>();
                    var index = 0;
                    foreach (var changeObj in ChangeObjectEntity)
                    {
                        if (Convert.ToBoolean(changeObj["IsFinish"]) && changeObj["F_plm_DateTime_finish"] == null)
                        {
                            finishedItems.Add(Convert.ToInt64(changeObj["Id"]));
                            this.View.Model.SetValue("F_plm_DateTime_finish", finishedTime, index);
                        }
                        else if (!Convert.ToBoolean(changeObj["IsFinish"]) && changeObj["F_plm_DateTime_finish"] != null)
                        {
                            cancelItems.Add(Convert.ToInt64(changeObj["Id"]));
                            this.View.Model.SetValue("F_plm_DateTime_finish", null, index);
                        }
                        index++;
                    }
                    FinishedItems(PLMContext, finishedItems, finishedTime);
                    CancelItems(PLMContext, cancelItems);
                    this.View.Model.DataChanged = dataChanged;//这里需要恢复下模型的修改标记，否则每次更新后退出会提示修改
                }
            }
        }

        private void FinishedItems(PLMContext ctx, List<long> finishedItems,DateTime finishedTime)
        {
            if (finishedItems.Count > 0)
            {
                string sql = string.Format("UPDATE T_PLM_STD_EC_ITEM SET F_plm_DateTime_finish= @FinishedTime WHERE FEntryID IN ({0})", string.Join(",", finishedItems));
                var paramters = PLMDBUtils.Instance.GetAParameter("@FinishedTime", KDDbType.DateTime, finishedTime);
                PLMDBUtils.Instance.Execute(ctx, sql, paramters);
            }
        }

        private void CancelItems(PLMContext ctx, List<long> cancelItems)
        {
            if (cancelItems.Count > 0)
            {
                string sql = string.Format("UPDATE T_PLM_STD_EC_ITEM SET F_plm_DateTime_finish = null WHERE FEntryID IN ({0})", string.Join(",", cancelItems));
                PLMDBUtils.Instance.Execute(ctx, sql);
            }
        }
    }
}

<2>扩展变更单，新增对应字段，并绑定上述插件

<5>更新变更单业务类型后验证
