Question

我在ASP.net C＃前端和Oracle 11g后端创建了一个网页。网页由一个ASP日历，两个DropDownList和一个GridView组成。根据日期和DropDownList的选择，数据将显示在GridView中。但是，当我选择任何组合数据时，不会在网格视图中显示。但是，当我通过sqldeveloper在数据库中写入相同的查询，即SELECT PALLET_NO，DATA_STS，MERGE，PLANT_CD，SHIFT，RACK_NO FROM WI_PALLET WHERE PROD_CD =＆＃39; PET＆＃39; AND INPUT_DT LIKE＆＃39; 24-06-15％＆＃39 ;;数据从数据库中检索。

using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.OracleClient;
using System.Data;
using System.Configuration;
using System.Drawing;
using System.IO;

public partial class _Default : System.Web.UI.Page
{
DataSet ds = new DataSet();
OracleConnection con = new OracleConnection("Data Source=10.31.41.103/ORCL;User ID=RL_PET;Password=RL_PET;Unicode=True");

protected void Page_Load(object sender, EventArgs e)
{

}

protected void Button1_Click1(object sender, EventArgs e)
{
    Label1.Visible = false;

    if (DropDownList1.Text == "Store In" && DropDownList2.Text == "ALL")
    {

        con.Open();
        OracleDataAdapter a = new OracleDataAdapter("SELECT PALLET_NO, DATA_STS, MERGE, PLANT_CD, SHIFT, RACK_NO FROM WI_PALLET WHERE PROD_CD = 'PET' AND INPUT_DT LIKE '"+ Calendar1.SelectedDate.Date+"%' ORDER BY PALLET_NO ASC", con);
        a.Fill(ds);
        int count = ds.Tables[0].Rows.Count;
        Label1.Text = count.ToString();
        Label1.Visible = true;
        GridView1.DataSource = ds;
        GridView1.DataBind();
        GridView1.Visible = true;
        con.Close();
    }
    else if (DropDownList1.Text == "Store In")
    {
        con.Open();
        OracleDataAdapter a = new OracleDataAdapter("SELECT PALLET_NO, DATA_STS, MERGE, PLANT_CD, SHIFT, RACK_NO FROM WI_PALLET WHERE PROD_CD = 'PET' AND  INPUT_DT LIKE '" + Calendar1.SelectedDate.Date+"%' AND SHIFT = '" + DropDownList2.Text + "' ORDER BY PALLET_NO ASC", con);
        a.Fill(ds);
        int count = ds.Tables[0].Rows.Count;
        Label1.Text = count.ToString(); 
        Label1.Visible = true;
        GridView1.DataSource = ds;
        GridView1.DataBind();
        GridView1.Visible = true;
        con.Close();

    }
 }
 }

Answer 1

我正在使用像这样的日历控件

//front end aspx page
    <asp:Calendar ID="Calendar1" runat="server"  
               SelectionMode="Day" 
               ShowGridLines="True">
//aspx.cs file
    Label1.Text = "The selected date is " + Calendar1.SelectedDate.ToShortDateString();

检查它是否对您有所帮助。

Answer 2

Lable1.Text = Calendar1.Selected.ToString("dd-MMMM-yyyy");
OracleDataAdapter a = new OracleDataAdapter("SELECT PALLET_NO, DATA_STS, MERGE, PLANT_CD, SHIFT, RACK_NO FROM WI_PALLET WHERE PROD_CD = 'PET' AND trunc(TO_DATE(INPUT_DT)) = '"+ Lable1.Text+"' ORDER BY PALLET_NO ASC", con);

这对我有用。感谢@shreesha的链接
