我有一个带有combobox和datetimepicker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，该值需要作为参数捕获并显示在报告上，其中日期等于所选日期，而itempiececode等于所选的组合框值。

Form-Piece Code.cs 报告 - Report6.rdlc Form Piece Code.cs上的ReportViewer - reportviewer1

突出显示的黄色是我需要的。
守则我太远了
填写报告查看器
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();
}
要填充Combobox，我使用了datasource和displaymemeber属性 **我使用报告向导生成report6 **
我在大多数程序中都使用了GUI，所以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report6上的参数，并将datetimepicker.text =设置为另一个参数，以便我可以在reportviewer中显示它？或者如果该计划有任何其他解决方法。
我在这里完全诚实，请不要将此作为主题关闭，或者让我停下来，因为我提供了我所有的理解，请帮助我，因为这是我项目的最后一部分，我我真的很想在假期之前完成它并与家人共度时光，感谢您的帮助
尝试使用代码，GUI有时不会删除它
namespace CorsicanaNetWeightProgram
{
public partial class PieceCode : Form
{
public string constr = "Data Source=KCMJF1XTR1\\SQLEXPRESS;Initial Catalog=CorsicanaNetWeight;Integrated Security=True";
public reportfiller fullpiecedetails;
public piecedescription piece;
PieceReport pr = new PieceReport();
public PieceCode()
{
InitializeComponent();
}
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.
// 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;
piece = new piecedescription();
fillpiece();
this.reportViewer1.RefreshReport();
}
private void fillpiece()
{
try
{
using(MSSQL.SqlConnection connection = new MSSQL.SqlConnection(constr))
{
connection.Open ();
using (MSSQL.SqlCommand command = new MSSQL.SqlCommand("SELECT Item + '-' + Description AS PieceDescription FROM dbo.[Piece Dimension Master Data]" ,connection))
{
MSSQL.SqlDataAdapter myadapter = new System.Data.SqlClient.SqlDataAdapter();
myadapter.SelectCommand = command;
myadapter.Fill(piece, "DataTable1");
comboBox1.DataSource = piece.DataTable1;
comboBox1.ValueMember = "PieceDescription";
comboBox1.DisplayMember = "PieceDescription";
}
}
}
catch (Exception) { /*Handle error*/ }
}
private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
reportViewer1.Visible = true;
{
using (MSSQL.SqlConnection connection = new MSSQL.SqlConnection(constr))
{
fullpiecedetails = new reportfiller();
connection.Open();
//MSSQL.SqlCommand command = new MSSQL.SqlCommand("SELECT * From EtimePunchDetail WHERE (EmpID = @empid) And (Paygroup = @paygroup) And (TransDate >= @fromdate) And (TransDate <= @todate)", connection);
MSSQL.SqlCommand command = new MSSQL.SqlCommand("SELECT * FROM dbo.[Piece Dimension Master Data] WHERE Item + '-' + Description = @piecedesc", connection);
{
MSSQL.SqlParameter parmEmp = new MSSQL.SqlParameter();
parmEmp.ParameterName = "@piecedesc";
parmEmp.Value = comboBox1.SelectedValue;
command.Parameters.Add(parmEmp);
MSSQL.SqlDataAdapter EtimePunchDetailTableAdapter = new System.Data.SqlClient.SqlDataAdapter();
EtimePunchDetailTableAdapter.SelectCommand = command;
EtimePunchDetailTableAdapter.Fill(fullpiecedetails, "DataTable1");
string exeFolder = Path.GetDirectoryName(Application.ExecutablePath);
string reportPath = exeFolder + @"\Report6.rdlc";
reportViewer1.LocalReport.ReportPath = reportPath;
reportViewer1.LocalReport.DataSources.Clear();
reportViewer1.LocalReport.DataSources.Add(new Microsoft.Reporting.WinForms.ReportDataSource("reportfiller_DataTable1", fullpiecedetails));
reportViewer1.RefreshReport();
reportViewer1.Refresh();
reportViewer1.Visible = true;
}
}
}
}
我收到以下错误＆＃34;价值不在预期范围内。＆＃34;在代码reportViewer1.LocalReport.DataSources.Add的这一部分（新的Microsoft.Reporting.WinForms.ReportDataSource（＆＃34; reportfiller_DataTable1＆＃34;，fullpiecedetails））;

假设您的日期参数名称是DateParameter。要设置值，我将执行以下操作：
ReportParameter rpDateParameter = new ReportParameter();
rpDateParameter.Name = "DateParameter";
rpDateParameter.Values.Add(dateTimePicker1.Value.ToString());
reportViewer1.LocalReport.SetParameters(new ReportParameter[] { rpDateParameter });
// Refresh the report
reportViewer1.RefreshReport();

我创建了一个新表单，添加了一个新报表，新数据集并通过GUI完成了所有操作 - 使用向导生成报表。
我将数据集编辑为以下代码
SELECT Item, Description, [Piece Category], Shape, [Deposit Weight], [Center Weight], [Center Weight Constant], [Coating Weight], [Coating Weight Constant], [Decorations Weight], [Inclusions Weight], [Center Diameter_LL], [Center Diameter_UL], [Center Length_LL], [Center Length_UL], [Center Width_LL], [Center Width_UL], [Center Height_LL], [Center Height_UL], [Center Weight Variation], [Coated Diameter_LL], [Coated Diameter_UL], [Coated Length_LL], [Coated Length_UL], [Coated Width_LL], [Coated Width_UL], [Coated Height_LL], [Coated Height_UL], [Coated Weight Variation], Item + '-' + Description AS [PieceDescription] FROM [Piece Dimension Master Data] WHERE **Item + '-' + Description = @piece**
然后在报告中添加了一个包含所有必需列的表
GUI已为我生成此代码
namespace CorsicanaNetWeightProgram
{
public partial class PieceCodepc : Form
{
public PieceCodepc()
{
InitializeComponent();
}
private void PieceCodepc_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'dataSet1.DataTable1' table. You can move, or remove it, as needed.
this.dataTable1TableAdapter.Fill(this.dataSet1.DataTable1);
}
private void button1_Click(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'empty.Piece_Dimension_Master_Data' table. You can move, or remove it, as needed.
this.Piece_Dimension_Master_DataTableAdapter.Fill(this.empty.Piece_Dimension_Master_Data, comboBox1.SelectedValue.ToString());
this.reportViewer1.RefreshReport();
}
}
}
我所做的只是将comboBox1.SelectedValue.ToString（）传递给DataTableAdapter并且IT工作!!!!!
