Question

我已经使用gridview中的行填充了数据集。现在我试图将其分配给RDLC报告，但我不知道如何。它必须需要.xsd，但我只需要分配程序化数据集。

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">

C＃

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        txtDateFrom.Text = DateTime.Now.ToString("dd/MMM/yyyy");
        txtDateTo.Text = DateTime.Now.ToString("dd/MMM/yyyy");

        ReportViewer1.AsyncRendering = false;
        ReportViewer1.SizeToReportContent = true;
        ReportViewer1.ZoomMode = ZoomMode.FullPage;
        this.ReportViewer1.Reset();
    }
}

protected void btnGenerateReport_Click(object sender, EventArgs e)
{
    dtRoom.Columns.Add(new DataColumn("ID", typeof(string)));
    dtRoom.Columns.Add(new DataColumn("RecievingDate", typeof(string)));
    dtRoom.Columns.Add(new DataColumn("FromMobileNo", typeof(string)));
    dtRoom.Columns.Add(new DataColumn("Message", typeof(string)));
    dtRoom.Columns.Add(new DataColumn("IsComplaint", typeof(bool)));
    bool var = false;
    for (int i = 0; i <= GridViewSmsComplaints.Rows.Count; i++)
    {
        DropDownList IsValid = (DropDownList) GridViewSmsComplaints.Rows[i].FindControl("ddlValidity");
        if (IsValid.SelectedValue == "1")
        {
            var = true;
            DataRow datarw = null;
            //dtRoom = new DataTable();
            datarw = dtRoom.NewRow();

            datarw[0] = GridViewSmsComplaints.Rows[i].Cells[0].Text;
            datarw[1] = GridViewSmsComplaints.Rows[i].Cells[1].Text;
            datarw[2] = GridViewSmsComplaints.Rows[i].Cells[2].Text;
            datarw[3] = GridViewSmsComplaints.Rows[i].Cells[3].Text;
            datarw[4] = var; // Convert.ToBoolean(GridViewSmsComplaints.Rows[i].Cells[4].Text);

            dtRoom.Rows.Add(datarw);
        }
    }
    GridViewSmsComplaints.DataSource = dtRoom;
    GridViewSmsComplaints.DataBind();
    Response.Write("Done");

    if (dtRoom.Rows.Count <= 0)
    {
        HiddenFieldSetMessage.Value = "NotExists";
        HiddenFieldShowMessage.Value = "True";
        ReportViewer1.Visible = false;
    }
    else
    {
        ReportDataSource rpds = new ReportDataSource("DataSet1", dtRoom);
        ReportViewer1.LocalReport.DataSources.Clear();
        ReportViewer1.LocalReport.DataSources.Add(rpds);
        ReportViewer1.Visible = true;
    }
}

我不知道也无法想办法怎么做？

Answer 1

在报告绑定代码中，您可以执行以下操作将数据表分配给报告

ReportDataSource reportDataSource = new ReportDataSource();
IList<string> names = ReportViewer1.LocalReport.GetDataSourceNames();
reportDataSource.Name = names[0];
reportDataSource.Value = rpds.Tables[0];
ReportViewer1.LocalReport.DataSources.Clear();
ReportViewer1.LocalReport.DataSources.Add(reportDataSource);
ReportViewer1.Visible = true;

这超出了您的需要..但请检查它，因为它可能是所有报告动态报告的最佳解决方案。

您可以构建动态创建RDLC和数据集的报告

为此，请从http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition/ReportDefinition.xsd 获取XSD报告定义，并使用XML架构定义工具xsd.exe将其转换为Class。

xsd file.xsd {/classes | /dataset} [/element:element]
         [/language:language] [/namespace:namespace]
         [/outputdir:directory] [URI:uri]

然后你需要一个ReportGenerator，它使用ReportDefinition.cs来创建报告和对象。

http://www.gotreportviewer.com/ 动态生成RDLC有一个很好的例子 - 矩阵。

我的意思是，您可以构建自己的RDLC（RDLC文件只是一个XML文件）并为您的目的更改任何内容（我用它来绘制我的徽标公司，添加页脚等，而不制作任何RDCL文件使用Visual Studio）。
