动态日历选择 [英] Dynamic Calendar selection

问题描述

我有两个文本框，我想分别从两个日历控件中选择日期。现在我已将两个文本框的autopostback属性设置为true。但它没有发生。每当我从日历中选择一个日期时，它就不会反映在文本框中，直到发生回发为止。



以下是我的代码： -

Hi,

I have two textboxes in which I want to select dates from two calendar controls respectively. Now I have set the autopostback property of two textboxes to true. But it is not happening. Whenever I am selecting a date from the calendar, it is not reflecting in the textbox until a postback happens.

Below is my code:-

using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Data.SqlClient;
using System.Web.Configuration;

public partial class _Default : System.Web.UI.Page 
{
    string stdt;
    string endt;
    string conn;
    
    protected void Page_Load(object sender, EventArgs e)
    {
        //txtfrmdt.Text = DateTime.Now.ToString();
        //txttodt.Text = DateTime.Now.ToString();
        if (!IsPostBack)
        {
            // string date2 = DateTime.Now.ToString();
            // string str = date2.Trim();
            //string date1 = str.Substring(0, 10);
            //string date1 = DateTime.Now.ToShortDateString();

            //DateTime dt = Convert.ToDateTime(date1);
            Calendar2.SelectedDate = DateTime.Now;
         //    Session["connstring"] = Request.QueryString["testupload"].ToString();
        }
            
            BindCalender();
           // bindgrid();

         //   DropDownList1.SelectedValue = Convert.ToString(Calendar1.SelectedDate);
         //   DropDownList1.SelectedItem.Text = Convert.ToString(Calendar1.SelectedDate);
    }
    protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
    {
        Calendar1.Visible = true;
      //  BindCalender();
    }
   
    protected void ImageButton2_Click1(object sender, ImageClickEventArgs e)
    {
        Calendar2.Visible = true;
    }
    public void BindCalender()
    {
        //txtfrmdt.Text = Calendar1.SelectedDate.ToString();
        //txttodt.Text = Calendar2.SelectedDate.ToString();
        stdt = Calendar1.SelectedDate.ToString();
        string s1 = stdt.Substring(0, 10);
        txtfrmdt.Text = s1.ToString();
        endt = Calendar2.SelectedDate.ToString();
        string s2 = endt.Substring(0, 10);
        txttodt.Text = s2.ToString();
        Calendar1.Visible = false;
        Calendar2.Visible = false;
      
        //Response.Redirect("Default2.aspx");
    }
   
    protected void Calendar1_SelectionChanged(object sender, EventArgs e)
    {
       // DropDownList1.Text = Convert.ToString(Calendar1.SelectedDate);
     //   DropDownList1.SelectedItem.Text = Convert.ToString(Calendar1.SelectedDate);
        stdt = Calendar1.SelectedDate.ToString();
        string s1 = stdt.Substring(0, 10);
        txtfrmdt.Text = s1.ToString();
     
        

        //Calendar1 .SelectedDate 
    }
    protected void Calendar2_SelectionChanged(object sender, EventArgs e)
    {
        endt = Calendar2.SelectedDate.ToString();
        string s2 = endt.Substring(0, 10);
        txttodt.Text = s2.ToString();
    }
}
