广分星空组2019年10月技术问题总结——复杂套打二开​

本帖主要是简单讲解一下复杂套打（套打数据源来自多个单据或动态列头等）如何通过二开实现

如下图，以服装行业的动态列头套打为例来说明

1、绑定好数据表格的数据源，由于列头的颜色、尺码都是动态加载，因此先布好局，然后拖文本控件，设置文本的数据为“动态字段”

2、使用表单插件处理套打数据，根据DataSourceId对应的处理数据

public override void OnPrepareNotePrintData(PreparePrintDataEventArgs e)
        {
            if (e.DataObjects != null && e.DataObjects.Count() > 0)
            {
                switch (e.DataSourceId)
                {
                    case "FBillHead":
                        e.DataObjects[0] = this.GetBillHeadObject(e);
                        break;
                    case "FTreeEntity":
                        e.DataObjects = this.GetDetailEntity(e);
                        break;
                    default:
                        break;
                }            }
            base.OnPrepareNotePrintData(e);
        }

/// <summary>
        /// 获取单据头数据
        /// </summary>
        /// <param name="e">e</param>
        /// <returns>单据头数据</returns>
        private DynamicObject GetBillHeadObject(PreparePrintDataEventArgs e)
        {
      //将动态字段的字段标识注册到数据包中
            string[] fieldArray = new string[] { "FParentMaterialNo","FParentMaterialName","FDesigner","FTechnician","FPatternMaker",
                                                 "FColor0", "FColor1", "FColor2", "FColor3", "FColor4",
                                                 "FSize0", "FSize1","FSize2", "FSize3", "FSize4","FSize5", "FSize6", "FSize7" };
           
   DynamicObject dataObject = e.DataObjects.FirstOrDefault();

   DynamicObjectType dot = dataObject.DynamicObjectType;
            var propertyArray = dataObject.DynamicObjectType.Properties;
            //注册动态字段
            foreach (var filed in fieldArray)
            {
                if (propertyArray.Contains(filed))
                    continue;
                dot.RegisterSimpleProperty(
                        filed,
                        typeof(object),
                        attributes: new SimplePropertyAttribute() { Alias = filed }
                        );
            }
            DynamicObject obj = new DynamicObject(dot);
            foreach (var p in dataObject.DynamicObjectType.Properties)
            {
                obj[p] = dataObject[p];
            }

   //以下就是针对自身需求对数据包赋值，单据头数据只需对e.DataObjects的第一个对象做处理，单据体的话则都要处理

   //参考代码
            DynamicObject bomSetObj = CommonData.GetBomSettingData(this.Context, bomFid);
            if (bomSetObj == null)
                return obj;
            string bomSetFid = bomSetObj["FID"].ToNullString();
            obj["FParentMaterialNo"] = bomSetObj["FMATERIALNO"];
            obj["FParentMaterialName"] = bomSetObj["FNAME"];
            obj["FDesigner"] = bomSetObj["FDesigner"];
            obj["FTechnician"] = bomSetObj["FTechnician"];
            obj["FPatternMaker"] = bomSetObj["FPatternMaker"];
            DynamicObjectCollection colorObjs = CommonData.GetParentColorData(this.Context, bomSetFid);
            DynamicObjectCollection sizeObjs = CommonData.GetParentSizeData(this.Context, bomSetFid);
            int count = colorObjs.Count > 5 ? 5 : colorObjs.Count;
            for (int i = 0; i < count; i++)
            {
                string key = "FColor" + i.ToString();
                obj[key] = colorObjs[i]["FNUMBER"].ToNullString() + Environment.NewLine + colorObjs[i]["FDATAVALUE"].ToNullString();
            }
            count = sizeObjs.Count > 8 ? 8 : sizeObjs.Count;
            for (int i = 0; i < count; i++)
            {
                string key = "FSize" + i.ToString();
                obj[key] = CommonTools.SplitSizeTitle(sizeObjs[i]["FDATAVALUE"].ToNullString());
            }
            return obj;
        }

处理单据体数据的方法GetDetailEntity就不贴出，做法跟单据头一样，只是需要对e.DataObjects里的所有对象都做处理，甚至于把e.DataObjects的对象清除掉自定义添加自己想要的对象都可以。

效果图如下：
