ASP 日历无法正常工作

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个日历、两个DropDownList和一个GridView组成。根据日期和 DropDownList 的 selection，数据将显示在 GridView 中。但是当我 select 时，任何组合数据都不会显示在网格视图中。但是，当我通过 sqldeveloper 在数据库中编写相同的查询时，即 SELECT PALLET_NO、DATA_STS、MERGE、PLANT_CD、SHIFT、RACK_NO FROM WI_PALLET WHERE PROD_CD = 'PET' AND INPUT_DT LIKE '24-06-15%';从数据库中检索数据。

using System;
using System.Collections.Generic;
using System.Linq;
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

我是这样使用日历控件的

//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();

看看对你有没有帮助。

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 link
