将gridview中的记录放入rdlc报告中

Question

我遇到了问题：

我已经从商店程序中填写了gridview。此gridview收到投诉，用户必须选择这些投诉是有效还是无效，然后在选择有效投诉后，必须在报告中显示。 简单来说，选择3个投诉作为有效并单击生成报告，它应包含这3个记录。

protected void btnSearch_Click(object sender, EventArgs e)
    {
        try
        {
            DateTime fromDate = DateTime.ParseExact(txtDateFrom.Text, "dd/MMM/yyyy", null);
            DateTime toDate = DateTime.ParseExact(txtDateTo.Text, "dd/MMM/yyyy", null);
            DataTable dt = ManageRecievedMessage.GetSmsComplaintsByDate(fromDate, toDate);
            if (dt.Rows.Count > 0)
            {

                GridViewSmsComplaints.DataSource = dt;
                GridViewSmsComplaints.DataBind();
                GridViewSmsComplaints.Visible = true;
            }
            else
            {

                dt.Rows.Add(dt.NewRow());
                GridViewSmsComplaints.DataSource = dt;
                GridViewSmsComplaints.DataBind();
                int totalcolums = GridViewSmsComplaints.Rows[0].Cells.Count;
                GridViewSmsComplaints.Rows[0].Cells.Clear();
                GridViewSmsComplaints.Rows[0].Cells.Add(new TableCell());
                GridViewSmsComplaints.Rows[0].Cells[0].ColumnSpan = totalcolums;
                GridViewSmsComplaints.Rows[0].Cells[0].Text = "No Data Found for this date combination";
                GridViewSmsComplaints.Visible = true;

            }
        }
        catch (Exception ex)
        {
            GridViewSmsComplaints.Visible = false;
            HiddenFieldSetMessage.Value = "NoDataForInput";
            HiddenFieldShowMessage.Value = "True";
        }

    }
    protected void GridViewSmsComplaints_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        //This Event is Triggered When Page is Changed in Gridview e.g. 1,2,3

        DateTime fromDate = DateTime.ParseExact(txtDateFrom.Text, "dd/MMM/yyyy", null);
        DateTime toDate = DateTime.ParseExact(txtDateTo.Text, "dd/MMM/yyyy", null);
        DataTable dt = ManageRecievedMessage.GetSmsComplaintsByDate(fromDate, toDate);

        if (dt.Rows.Count != 0)
        {
            GridViewSmsComplaints.PageIndex = e.NewPageIndex;
            GridViewSmsComplaints.DataSource = dt;
            GridViewSmsComplaints.DataBind();
            GridViewSmsComplaints.Visible = true;
        }
    }

                    </asp:TemplateField>
               </Columns>
    </asp:GridView>

我知道报告等但是如何在报告中选择有效记录？
