Grid++Report(GridPPReport) 代码绑定数据源(填充明细数据)

网上看了好几个方法，要么就是用报表直接连数据库的，另外一个哥们，写的是用另外一个事件绑定数据源的，那样的问题就是，还要另外考虑报表对象怎么传递

后面调整思路，想了想，调整了下代码。改进了一下，主要就是记录一下，另外呢，放出来看看还有什么不对的，需要改进。 

 

private void GridPrintPreview(string rptPath, Dictionary<string, object> dic, DataTable dt = null)
{
    GridppReport report = new GridppReport();
    report.LoadFromFile(rptPath);
    if (dic.Count > 0)
    {
        foreach (string k in dic.Keys)
            report.ParameterByName(k).AsString = dic[k].ToString();
    }
    if (dt != null && dt.Rows.Count > 0)
    {
        report.FetchRecord += new _IGridppReportEvents_FetchRecordEventHandler(() =>
        {
            Dictionary<int, int> columnDic = new Dictionary<int, int>();
            //Report.DetailGrid.Recordset.Fields的索引从1开始
            int fieldCount = report.DetailGrid.Recordset.Fields.Count;
            for (int x = 0; x < fieldCount; x++)
            {
                string columnName = report.DetailGrid.Recordset.Fields[x + 1].Name;
                for (int y = 0; y < dt.Columns.Count; y++)
                {
                    if (columnName == dt.Columns[y].ColumnName)
                    {
                        columnDic.Add(x, y);
                        break;
                    }
                }
            }
            for (int x = 0; x < dt.Rows.Count; x++)
            {
                report.DetailGrid.Recordset.Append();
                for (int y = 0; y < columnDic.Count; y++)
                {
                    report.DetailGrid.Recordset.Fields[y + 1].GetDisplayTextScript = "";//不设置这个值会报错
                    report.DetailGrid.Recordset.Fields[y + 1].Value = dt.Rows[x][columnDic[y]];
                }
                report.DetailGrid.Recordset.Post();
            }
        });
    }
    report.PrintPreview(true);
}
