sql2005 reporting service，我总算找到一个完全程序化绑定报表（ado.net dataset 绑定reprot)的方案,谁能再给我些其他建议呢？ Carlwave

    想想还是放首页吧，希望更多的人来交流……
    花了很长时间研究reporting service，也看了N多文章和资料，但还是处于迷迷糊糊混沌混沌的状态。
    知道reporting service有很多强大的功能，也通过范例能过实现，但是对于报表的设计，最主要的是报表数据源和datasets的设计有点不是最理解，不过目前总算是找到一个解决方案，等整理好之后发出来给大家
    http://msdn2.microsoft.com/en-us/library/aa337091.aspx这篇文章讲述了如何用ado.net dataset作为数据源去绑定report。我按照范例做确实成功了。简略代码：
Protected Sub Page_Init(ByVal sender As Object, _
                    ByVal e As System.EventArgs) Handles Me.Init

        If Not Page.IsPostBack Then

            'Set the processing mode for the ReportViewer to Local
            ReportViewer1.ProcessingMode = ProcessingMode.Local

            Dim localReport As LocalReport
            localReport = ReportViewer1.LocalReport

            localReport.ReportPath = "Reports\Default.rdlc"

            Dim dataset As New DataSet("Sales Order Detail")

            Dim salesOrderNumber As String = "SO43661"

            'Get the sales order data
            GetSalesOrderData(salesOrderNumber, dataset)

            'Create a report data source for the sales order data
            Dim dsSalesOrder As New ReportDataSource()
            dsSalesOrder.Name = "SalesOrder"
            dsSalesOrder.Value = dataset.Tables("SalesOrder")

            localReport.DataSources.Add(dsSalesOrder)

            'Get the sales order detail data
            GetSalesOrderDetailData(salesOrderNumber, dataset)

            'Create a report data source for the sales
            'order detail data
            Dim dsSalesOrderDetail As New ReportDataSource()
            dsSalesOrderDetail.Name = "SalesOrderDetail"
            dsSalesOrderDetail.Value = _
                dataset.Tables("SalesOrderDetail")

            localReport.DataSources.Add(dsSalesOrderDetail)

            'Create a report parameter for the sales order number
            Dim rpSalesOrderNumber As New ReportParameter()
            rpSalesOrderNumber.Name = "SalesOrderNumber"
            rpSalesOrderNumber.Values.Add("SO43661")

            'Set the report parameters for the report
            Dim parameters() As ReportParameter = {rpSalesOrderNumber}
            localReport.SetParameters(parameters)

        End If

    End Sub

但是问题的关键在于我不知道如何去设计这个基于xml的rdlc文件，在范例Sales Order Detail.rdlc中
已经默认存在了  <DataSources>
    <DataSource Name="AdventureWorks">
      <DataSourceReference>AdventureWorks</DataSourceReference>
      <rd:DataSourceID>9d4e7b1f-0315-4083-8ff3-aa70c1fb2920</rd:DataSourceID>
    </DataSource>
  </DataSources>
和    
    <DataSet Name="SalesOrderDetail">
      <Query>
        <rd:UseGenericDesigner>true</rd:UseGenericDesigner>
        <CommandText>SELECT      SOD.SalesOrderDetailID, SOD.OrderQty, SOD.UnitPrice,
            CASE WHEN SOD.UnitPriceDiscount IS NULL THEN 0 ELSE SOD.UnitPriceDiscount END AS UnitPriceDiscount,
            SOD.LineTotal, SOD.CarrierTrackingNumber, SOD.SalesOrderID, P.Name, P.ProductNumber
FROM        Sales.SalesOrderDetail SOD INNER JOIN
            Production.Product P ON SOD.ProductID = P.ProductID INNER JOIN
            Sales.SalesOrderHeader SOH ON SOD.SalesOrderID = SOH.SalesOrderID
WHERE       (SOH.SalesOrderNumber = @SalesOrderNumber)
ORDER BY    SOD.SalesOrderDetailID</CommandText>
        <QueryParameters>
          <QueryParameter Name="@SalesOrderNumber">
            <Value>=Parameters!SalesOrderNumber.Value</Value>
          </QueryParameter>
        </QueryParameters>
        <Timeout>30</Timeout>
        <DataSourceName>AdventureWorks</DataSourceName>
      </Query>
      <Fields>
        <Field Name="SalesOrderDetailID">
          <rd:TypeName>System.Int32</rd:TypeName>
          <DataField>SalesOrderDetailID</DataField>
        </Field>
        <Field Name="OrderQty">
          <rd:TypeName>System.Int16</rd:TypeName>
          <DataField>OrderQty</DataField>
        </Field>
        <Field Name="UnitPrice">
          <rd:TypeName>System.Decimal</rd:TypeName>
          <DataField>UnitPrice</DataField>
        </Field>
        <Field Name="UnitPriceDiscount">
          <rd:TypeName>System.Decimal</rd:TypeName>
          <DataField>UnitPriceDiscount</DataField>
        </Field>
        <Field Name="LineTotal">
          <rd:TypeName>System.Decimal</rd:TypeName>
          <DataField>LineTotal</DataField>
        </Field>
        <Field Name="CarrierTrackingNumber">
          <rd:TypeName>System.String</rd:TypeName>
          <DataField>CarrierTrackingNumber</DataField>
        </Field>
        <Field Name="SalesOrderID">
          <rd:TypeName>System.Int32</rd:TypeName>
          <DataField>SalesOrderID</DataField>
        </Field>
        <Field Name="Name">
          <rd:TypeName>System.String</rd:TypeName>
          <DataField>Name</DataField>
        </Field>
        <Field Name="ProductNumber">
          <rd:TypeName>System.String</rd:TypeName>
          <DataField>ProductNumber</DataField>
        </Field>
      </Fields>
    </DataSet>
  </DataSets>
就是因为在rdlc文件中包含了dataset才使结果是正确的，但是这样的rdlc文件是如何设计出来的呢？我已经发觉在rdlc文件中的连接都是不需要的，所以我可以手动写这个xml文件，我最终要达到的是能够在一个reportviewer上面通过传递参数动态的绑定不同的reports，目前就手工写的方法。

谁也有研究过？？大家讨论讨论，交流下经验。
