Question

我有一个从数据库中填充的数据网格视图。在表格中，文本框和下拉列表中很少有列可以获得用户输入。我想将所有这些数据传递到水晶报表而不插入数据库 并打印为报表中的表格。可以更改行的数量。所以我不能设计它的表。所以我想打印水平线以分隔细节（不需要垂直线）。我该怎么办？在这里，我添加了 aspx 代码

首先将Gridview转换为Datatable

 protected void btnExportCrstalReport_Click(object sender, EventArgs e)
    {
        DataTable _datatable = new DataTable();
        for (int i = 0; i < grdReport.Columns.Count; i++)
        {
            _datatable.Columns.Add(grdReport.Columns[i].ToString());
        }
        foreach (GridViewRow row in grdReport.Rows)
        {
            DataRow dr = _datatable.NewRow();
            for (int j = 0; j < grdReport.Columns.Count; j++)
            {
                if (!row.Cells[j].Text.Equals("&nbsp;"))
                    dr[grdReport.Columns[j].ToString()] = row.Cells[j].Text;
            }

            _datatable.Rows.Add(dr);
        }
        ExportDataTableToPDF(_datatable);
    }

此处将数据绑定到Crystal报表

 void ExportDataTableToPDF(Datatable _datatable)
   {
   }

如何将Gridview中的详细信息传递给报表？
