如何将日期作为参数传递给crystal reportviewer

问题描述

我有两个表一个表包含产品信息，另一个表包含日期信息。我想从日期选择器的选定日期使用这两个表生成水晶报告。我可以生成没有日期范围的报告。

所以如何将这两个日期参数传递给我的crystalreportviewer。



什么我试过了：



private ProductSell Getdata（）

{

DateTime sdt = dateTimePicker1 .Value.Date;

DateTime edt = dateTimePicker2.Value.Date;

SqlConnection connection = new SqlConnection（cn）;



SqlCommand cmd = new SqlCommand（选择ProductName，sum（ProductCost）为ProductCost，Sum（ProductPrice）为ProductPrice，sum（ProductQuantity）为ProductQuantity，来自ProductSell，其中GROUP BY ProductName，连接）;



// SqlCommand cmd = new SqlCommand（SELECT ProductSell.ProductName，sum（ProductSell.ProductCost）as pc，sum（ProductSell.ProductPrice）as pp，sum（ProductSell.ProductQuantity） as pq FROM ProductSell INNER JOIN Project ON ProductSell.ProjectID = Project.ProjectID WHERE（ Project.Date> ='+ sdt +'）AND（Project.Date< ='+ edt +'）GROUP BY ProductSell.ProductName，connection）;



SqlDataAdapter sda = new SqlDataAdapter（cmd）;

ProductSell dsproductsell = new ProductSell（）;

sda.Fill（dsproductsell，ProdSellDT）;

返回dsproductsell;

}



private void button1_Click（object sender，EventArgs e）

{

ProductSellReport psreport = new ProductSellReport（）;

ProductSell dsproductsell = Getdata（）;

psreport.SetDataSource（dsproductsell）;

this.ProductSellReportViewer.ReportSource = psreport;

this.ProductSellReportViewer.RefreshReport（）;

}

I have two table one table contain product information and another table contain date information.I want to generate crystal report using these two tables from selected date from date picker. i am able to generate report without date range.
so how to pass those two date parameter to my crystalreportviewer.

What I have tried:

private ProductSell Getdata()
{
DateTime sdt = dateTimePicker1.Value.Date;
DateTime edt = dateTimePicker2.Value.Date;
SqlConnection connection= new SqlConnection(cn);

SqlCommand cmd = new SqlCommand("Select ProductName,sum(ProductCost)as ProductCost,Sum(ProductPrice)as ProductPrice,sum(ProductQuantity)as ProductQuantity from ProductSell Where GROUP BY ProductName", connection);

// SqlCommand cmd = new SqlCommand("SELECT ProductSell.ProductName, sum(ProductSell.ProductCost)as pc,sum(ProductSell.ProductPrice)as pp,sum(ProductSell.ProductQuantity)as pq FROM ProductSell INNER JOIN Project ON ProductSell.ProjectID = Project.ProjectID WHERE (Project.Date >='"+sdt+"') AND (Project.Date <='"+edt+"') GROUP BY ProductSell.ProductName", connection);

SqlDataAdapter sda = new SqlDataAdapter(cmd);
ProductSell dsproductsell = new ProductSell();
sda.Fill(dsproductsell, "ProdSellDT");
return dsproductsell;
}

private void button1_Click(object sender, EventArgs e)
{
ProductSellReport psreport = new ProductSellReport();
ProductSell dsproductsell = Getdata();
psreport.SetDataSource(dsproductsell);
this.ProductSellReportViewer.ReportSource = psreport;
this.ProductSellReportViewer.RefreshReport();
}

推荐答案

SqlCommand cmd = new SqlCommand("SELECT ProductSell.ProductName, sum(ProductSell.ProductCost)as pc,sum(ProductSell.ProductPrice)as pp,sum(ProductSell.ProductQuantity)as pq FROM ProductSell INNER JOIN Project ON ProductSell.ProjectID = Project.ProjectID WHERE (Project.Date >=@sdt) AND (Project.Date <=@edt) GROUP BY ProductSell.ProductName", connection);
              cmd.Parameters.Add("@sdt", startDateObj);
              cmd.Parameters.Add("@sdt", endDateObj);

总是使用 []
