Rdlc报告C＃.net

Question

在.rdlc报告中需要帮助。

我有一个.RDLC报告，类似于附件。

在这里，我可以为每个学生每次打印一张身份证。 我可以根据学生唯一的无当前会话收集所需的数据，并将其传递给rdlc报告以进行打印。

现在的问题是，如果我想为所有学生打印/生成ID卡，而不是每次都打印一张入场卡，我现在该怎么办？ 我可以获得所有学生的数据，但我不知道如何在报告中表示这些数据以实现此目标。

private void btnsearch_Click(object sender, EventArgs e)
        {

                if (txtcardid.Text == "")
                {
                    txtcardid.Focus();
                    return;
                }
                else if (txtcardid.Text != "")
                {

                    string sel = "select *  from tbl_student where Card_id='" + txtcardid.Text + "' ";
                    DataTable datTab = mod.filldatatbl(sel);
                    if (datTab.Rows.Count.ToString() == "0")
                    {
                        label2.ForeColor = Color.Red;
                        label2.Text = "No Records Found";
                        SqlDataAdapter sda = new SqlDataAdapter();
                        BindingSource bds = new BindingSource();
                        bds.DataSource = datTab;

                        sda.Update(datTab);
                        this.tbl_studentBindingSource.DataSource = bds;
                        this.reportViewer1.RefreshReport();
                        btnsearch.Text = datTab.Rows.Count.ToString();
                    }
                    else if (datTab.Rows.Count.ToString() != "0")
                    {
                        //string sel1 = "select distinct Card_id,StudentName,RollNo,class,ContactNo,section,dates,totalhour,status1,  min(Intime) as Intime, max(Outtime) as Outtime  from tbl_stuAtten where Card_id='" + textBox1.Text + "' and dates between '" + dateTimePicker1.Text + "' and '" + dateTimePicker2.Text + "' group by Card_id,StudentName,RollNo,class,ContactNo,section,dates,totalhour,status1";
                        //DataTable datTab1 = mod.filldatatbl(sel1);
                        string cnt;
                        cnt = datTab.Rows.Count.ToString();
                        label2.ForeColor = Color.Green;
                        label2.Text = "" + cnt + " : Records Found ";
                        SqlDataAdapter sda = new SqlDataAdapter();
                        BindingSource bds = new BindingSource();
                        bds.DataSource = datTab;

                        sda.Update(datTab);

                        btnsearch.Text = datTab.Rows.Count.ToString();
                        this.tbl_studentBindingSource.DataSource = bds;
                        this.reportViewer1.RefreshReport();
                    }
                }


            //this.reportViewer1.RefreshReport();
        }

任何帮助将不胜感激； 我已经花了几个小时在谷歌上搜索，但一点都没有头绪

在报告正文中创建一个列表，然后在该列表中设计身份证。
