如何在报表上显示组合框值

我有一个带有组合框和日期时间选择器的表单。 我希望用户从组合框中选择一个值并选择一个日期，并且需要将此值捕获为参数并显示在报表上，其中日期等于所选日期，itempiececode 等于所选组合框值。

突出显示的黄色是我需要的。

到目前为止我拥有的代码

填充报表查看器

private void PieceCode_Load(object sender, EventArgs e)
{
    // TODO: This line of code loads data into the 'CorsicanaNetWeightDataSet9.CandyPieceSize' table. You can move, or remove it, as needed.
    this.CandyPieceSizeTableAdapter.Fill(this.CorsicanaNetWeightDataSet9.CandyPieceSize);
    // TODO: This line of code loads data into the 'CorsicanaNetWeightDataSet4.PieceDimensionMasterDataUpdate' table. You can move, or remove it, as needed.
    this.PieceDimensionMasterDataUpdateTableAdapter.Fill(this.CorsicanaNetWeightDataSet4.PieceDimensionMasterDataUpdate);
    // TODO: This line of code loads data into the 'corsicanaNetWeightDataSet4piece.Item_Piece' table. You can move, or remove it, as needed.
    this.item_PieceTableAdapter.Fill(this.corsicanaNetWeightDataSet4piece.Item_Piece);
    PieceReport pr = new PieceReport();
    reportViewer1.Visible = false;
    this.reportViewer1.RefreshReport();
}

为了填充组合框，我使用了数据源和显示memeber属性** 我使用报告向导生成报告6**

我在大部分程序中都使用了GUI，因此没有太多代码可以共享

我需要的摘要我需要将 Combobox1.selectedtext 设置为等于 Report6 上的一个参数，并将 DateTimepicker.text = 设置为另一个参数，以便我可以在我的报表查看器中显示它？或者该程序是否有任何其他解决方法。

在这里完全诚实，请不要将其作为题外话关闭，或者让我失望，因为我已经提供了我所拥有的一切供您理解，请帮助我，因为这是我项目的最后一部分，我真的很想在假期前完成它并与家人共度时光，感谢您的所有帮助

用代码尝试过，GUI 有时不会削减它
