this is Incomplete_Prodcut.aspx file

</表单>

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Incomplete_Prodcut.aspx.cs" Inherits="albaraka.Report.Incomplete_Prodcut" %> <%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div style="width: 1116px"> <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <br /> Type: <asp:TextBox ID="type" runat="server" Width="64px"></asp:TextBox>  Category: <asp:TextBox ID="category" runat="server" Width="78px"></asp:TextBox>  Country: <asp:TextBox ID="country" runat="server" Width="85px"></asp:TextBox>  Subsidary: <asp:TextBox ID="subsidary" runat="server" Width="72px"></asp:TextBox>   Date: <asp:TextBox ID="date" runat="server" Width="100px"></asp:TextBox>      <asp:Button ID="btnShow" runat="server" Text="Button" Width="56px" />  <rsweb:ReportViewer ID="ReportViewer1" runat="server" Height="397px" Width="951px" style="margin-top: 17px; margin-right: 0px;"></rsweb:ReportViewer> </div> </form> </body> </html>

这是Incomplete_Prodcut.aspx.cs文件

protected void Page_Load(object sender, EventArgs e)
{

}

protected void btnShow_Click(object Sender, EventArgs e)
{
    ShowReport();
}

private void ShowReport()
{
    //Reset
    ReportViewer1.Reset();

    //DataSource
    ALBARAKA_Incomplete_Product_DataSet dt = GetData(type.Text, category.Text,subsidary.Text,country.Text, DateTime.Parse(date.Text));
    ReportDataSource rds = new ReportDataSource("Incomplete_Product_DataSet", dt);

    ReportViewer1.LocalReport.DataSources.Add(rds);

    //Path
    ReportViewer1.LocalReport.ReportPath = "~/Report/Incomplete_Product.rdlc";

    //Paramaeters
    ReportParameter[] rptParams = new ReportParameter[] {
        new ReportParameter("type",type.Text),
        new ReportParameter("category", category.Text),
        new ReportParameter("country",country.Text),
        new ReportParameter("subsidary",subsidary.Text),
        new ReportParameter("date",date.Text),
    };
    ReportViewer1.LocalReport.SetParameters(rptParams);

    //Refersh
    ReportViewer1.LocalReport.Refresh();

}

private ALBARAKA_Incomplete_Product_DataSet GetData(string type, string category, string country, string subsidary, DateTime? date)
{

    ALBARAKA_Incomplete_Product_DataSet dt = new ALBARAKA_Incomplete_Product_DataSet();
    string connStr = System.Configuration.ConfigurationManager.ConnectionStrings["AB_ReportEntities"].ConnectionString;
    using (SqlConnection cn = new SqlConnection(connStr))
    {

        SqlCommand cmd = new SqlCommand("FindIncomplete_Products", cn);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.Add("@type", SqlDbType.NVarChar).Value = type;
        cmd.Parameters.Add("@category", SqlDbType.NVarChar).Value = category;
        cmd.Parameters.Add("@country", SqlDbType.NVarChar).Value = country;
        cmd.Parameters.Add("@subsidary", SqlDbType.NVarChar).Value = subsidary;
        cmd.Parameters.Add("@date", SqlDbType.DateTime).Value = date;

        SqlDataAdapter adp = new SqlDataAdapter(cmd);

        adp.Fill(dt);
    }

    return dt;
}

我在上面表单的 OnClick 事件中插入了调试点，但是一旦在调试模式下运行此应用程序并单击btnShow"按钮，此应用程序就不会指向此调试点.我的方法有什么问题?

I inserted debug point inside the OnClick event of above form, but Once run this application in debug mode and click "btnShow" button this application does not point to this debug point. whats wrong with my approach ?
