C# 如何在StimulReport中显示从DataGridView筛选的数据？

如何将从DataGridView筛选的数据显示到StimulReport中

我测试了以下代码：

public void CreateStimulSoftReport()
{
    System.Diagnostics.Debug.WriteLine("CreateStimulSoftReport ...");
    StiReport stReport = new StiReport();

    //If Template has already been created then load that template
    stReport.Load(@"C:\Tools\Test\ReportExcel.mrt");
    stReport.Compile();

    #region Report Data Creation Section

    DataSet dataSet = new DataSet("DS1");

    System.Data.DataTable table = new System.Data.DataTable("Demo");
    table.TableName = "DataBand1";
    table.Columns.Add(new DataColumn("id", typeof(int)));
    table.Columns.Add(new DataColumn("tel_usage_new", typeof(string)));
    table.Columns.Add(new DataColumn("tel_usage_former", typeof(string)));
    table.Columns.Add(new DataColumn("terminal_cable30", typeof(string)));
    table.Columns.Add(new DataColumn("terminal_cable40", typeof(string)));
    table.Columns.Add(new DataColumn("terminal_voip_u6", typeof(string)));
    table.Columns.Add(new DataColumn("terminal_cable40_u47", typeof(string)));
    table.Columns.Add(new DataColumn("description", typeof(string)));

    //Fill Data in Table
    //Here GRID_VIEW_DATA_ITEMS is your ObservableCollection or any collection that is bound to your DataGrid
    foreach (DataGridViewRow row in dataGridView1.Rows)
    {
        System.Diagnostics.Debug.WriteLine("CreateStimulSoftReport ID : " + row.Cells[0].Value.ToString());
        DataRow dr = table.NewRow();
        dr["id"] = row.Cells[0].Value.ToString();
        dr["tel_usage_new" ] = row.Cells[1].Value.ToString();
        dr["tel_usage_former"] = row.Cells[2].Value.ToString();
        dr["terminal_cable30"] = row.Cells[3].Value.ToString();
        dr["terminal_cable40"] = row.Cells[4].Value.ToString();
        dr["terminal_voip_u6"] = row.Cells[5].Value.ToString();
        dr["terminal_cable40_u47"] = row.Cells[6].Value.ToString();
        dr["description"] = row.Cells[7].Value.ToString();
        System.Diagnostics.Debug.WriteLine("CreateStimulSoftReport tel_usage_new : " + dr["tel_usage_new"]);
        table.Rows.Add(dr);
    }
    System.Diagnostics.Debug.WriteLine("Create StimulSoftReport table Rows : " + table.Rows.Count);

    dataSet.Tables.Add(table.Copy());
    System.Diagnostics.Debug.WriteLine("CreateStimulSoftReport dataSet tables : " + dataSet.Tables.Count);

    #endregion

    //Register Report Dataset with Stimulsoft Report
    stReport.RegData("DS1", "DS1", dataSet);
    stReport["date_time"] = DateTime.Now.ToString("yyyy-MM-dd hh-mm-ss dddd");
    stReport.Dictionary.Synchronize();
    stReport.Render();
    stReport.Show();

}

但它会显示一个空白的报告页。

1-您必须在报告中使用数据带
2-数据带必须与DS1一起分配
3-在RegData之前写下：

stReport.Tables[0].TableName = "DS1";
stReport.Namespace = "DS1";
stReport.DataSources.Clear();
stReport.Dictionary.DataSources.Clear();

4-如果您需要变量“日期\时间”，请在报告中创建变量并使用设置值

stReport.Dictionary.Variables["date_time"].Value = DateTime.Now.ToString("yyyy-MM-dd hh-mm-ss dddd");
