c# - 在 VS2013 报表查看器中使用使用相同数据集的多个报表表创建报表

Answer 1

抱歉有点长。对于每一个Report，我们都有多种方法。正如评论部分中提到的，我生成了相同的（不完全是，但结果是相同的）报告，列表如下：

1. 用一张表创建一个DataSet有 7Column秒。

2. 开始一个新的Report，在里面添加一个List完整的空间，然后在里面添加 7 个TextBoxes（从 Col1 到 Col 7 的数据）List。

3. 设置Visibility这些TextBoxes 以便Show or hide based on an expression在我们传递 emty 字符串数据时隐藏它们：

文本框1：=IIF(Fields!Col1.Value="",TRUE,FALSE)

文本框2：=IIF(Fields!Col2.Value="",TRUE,FALSE)

文本框 3 到 7：=IIF(Fields!Col3.Value & Fields!Col4.Value & Fields!Col5.Value & Fields!Col6.Value & Fields!Col7.Value = "",TRUE,FALSE)

4. 示例数据结构：

一些简单的事情：

class clsDataStruct
{
    public class ItemType
    {
        public string Name { get; set; }
    }

    public class Item
    {
        public string Name { get; set; }
        public ItemType Type { get; set; }
        public int Cost { get; set; }
        public int Prize { get; set; }
    }

    public class BillByItem
    {
        public DateTime DateSold { get; set; }
        public Item Item { get; set; }
    }
}

5. AForm查看结果：

添加一个Form，一个ReportViewer到那个Form，设置我们之前创建Report的那个ReportViewer。然后在Form'sLoad事件中，添加一些代码来生成一些随机数据（这是你取数据的地方）然后生成我们的Report：

    //for data generation
    static Random rdn = new Random();

    //some list to hold data
    List<clsDataStruct.ItemType> lstItemType = new List<clsDataStruct.ItemType>();
    List<clsDataStruct.Item> lstItem = new List<clsDataStruct.Item>();
    List<clsDataStruct.BillByItem> lstBill = new List<clsDataStruct.BillByItem>();

    //this is what user choose to filter the report
    //user choose to report which item type
    List<clsDataStruct.ItemType> lstItemTypeByUser = new List<clsDataStruct.ItemType>();
    //date begin and end of report
    DateTime dteStart;
    DateTime dteEnd;

    private void Form1_Load(object sender, EventArgs e)
    {
        //create 3 ItemType
        for (int i = 1; i < 4; i++)
        {
            clsDataStruct.ItemType itt = new clsDataStruct.ItemType();
            itt.Name = "Item Type " + i.ToString();
            lstItemType.Add(itt);
        }

        //create 12 Item
        for (int i = 1; i < 13; i++)
        {
            clsDataStruct.Item item = new clsDataStruct.Item();
            item.Name = "Item " + i.ToString();
            item.Type = lstItemType[i % 3];
            item.Cost = rdn.Next(10);
            item.Prize = item.Cost + rdn.Next(5);
            lstItem.Add(item);
        }

        //create 30 BillByItem in next 3 month
        for (int i = 1; i < 31; i++)
        {
            clsDataStruct.BillByItem bill = new clsDataStruct.BillByItem();
            bill.DateSold = DateTime.Now.AddDays(rdn.Next(90));
            bill.Item = lstItem[rdn.Next(12)];
            lstBill.Add(bill);
        }
        //set the filters
        //add 2 random type to the filter
        lstItemTypeByUser.Add(lstItemType.Where(s => !lstItemTypeByUser.Contains(s)).ToList()[rdn.Next(lstItemType.Where(s => !lstItemTypeByUser.Contains(s)).ToList().Count)]);
        lstItemTypeByUser.Add(lstItemType.Where(s => !lstItemTypeByUser.Contains(s)).ToList()[rdn.Next(lstItemType.Where(s => !lstItemTypeByUser.Contains(s)).ToList().Count)]);
        //date start and end is one month from date we have data
        dteStart = DateTime.Now.AddDays(rdn.Next(60) - 30);
        dteEnd = DateTime.Now.AddMonths(3).AddDays(rdn.Next(60) - 30);

        this.reportViewer1.LocalReport.DataSources.Clear();
        dsReports.dtLyLichTrichNgangDataTable dtLyLichTrichNgang = new dsReports.dtLyLichTrichNgangDataTable();

        //Simple title, replace with yours
        dtLyLichTrichNgang.Rows.Add("ITEM INVENTORY SOLD " + dteStart.ToShortDateString() + " - " + dteEnd.ToShortDateString(), "", "", "", "", "", "");
        //empty row
        dtLyLichTrichNgang.Rows.Add(" ", "", "", "", "", "", "");

        DateTime dteFirstOfCycle;
        DateTime dteLastOfCycle;
        //cycle through months and fill data to datatable, maybe week or quarter
        for (dteFirstOfCycle = new DateTime(dteStart.Year, dteStart.Month, 1); dteFirstOfCycle < dteEnd; dteFirstOfCycle = dteFirstOfCycle.AddMonths(1))
        {
            dteLastOfCycle = dteFirstOfCycle.AddMonths(1).AddDays(-1);

            //take BillByItem in each month
            var billMonth = lstBill.Where(s => s.DateSold >= dteFirstOfCycle && s.DateSold <= dteLastOfCycle).OrderBy(s => s.DateSold);

            dtLyLichTrichNgang.Rows.Add("FROM " + dteFirstOfCycle.ToShortDateString() + " TO " + dteLastOfCycle.ToShortDateString(), "", "", "", "", "", "");
            //empty row
            dtLyLichTrichNgang.Rows.Add(" ", "", "", "", "", "", "");

            //cycle through each item type
            foreach (clsDataStruct.ItemType itt in lstItemTypeByUser)
                //have sold something
                if (billMonth.Where(s => s.Item.Type == itt).Count() != 0)
                {
                    //itemtype
                    dtLyLichTrichNgang.Rows.Add(itt.Name.ToUpper(), "", "", "", "", "", "");
                    //detail header
                    dtLyLichTrichNgang.Rows.Add("", "", "Name", "Cost", "Prize", "Profit", "Date Sold");
                    //cycle through each bill
                    foreach (clsDataStruct.BillByItem bill in billMonth)
                        dtLyLichTrichNgang.Rows.Add("", "", bill.Item.Name, bill.Item.Cost, bill.Item.Prize, bill.Item.Prize - bill.Item.Cost, bill.DateSold.ToShortDateString());
                    //total row
                    dtLyLichTrichNgang.Rows.Add("", "", "TOTAL", billMonth.Sum(s => s.Item.Cost), billMonth.Sum(s => s.Item.Prize), billMonth.Sum(s => s.Item.Prize - s.Item.Cost), "");
                }
                //sold nothing
                else
                {
                    dtLyLichTrichNgang.Rows.Add(itt.Name.ToUpper(), "", "", "", "", "", "");
                    dtLyLichTrichNgang.Rows.Add("Nothing sold", "", "", "", "", "", "");
                    //empty row
                    dtLyLichTrichNgang.Rows.Add(" ", "", "", "", "", "", "");
                }
            //empty row
            dtLyLichTrichNgang.Rows.Add(" ", "", "", "", "", "", "");
        }

        this.reportViewer1.LocalReport.DataSources.Add(new ReportDataSource("dsLyLichTrichNgang", (DataTable)dtLyLichTrichNgang));
        this.reportViewer1.RefreshReport();
    }

6. 结果：

通过一些调整TextBox你BorderStyle可以有你想要的Report。
