我需要知道是否可以在文本框中插入日期,然后在日历中选择该日期。我在 Microsoft Visual Studio Express 2012 for Web 中使用日历。

下面是通过选择日历上的日期将日期插入文本框的代码。(但是我想做相反的事情)

默认.aspx

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

 <html xmlns="http://www.w3.org/1999/xhtml">
 <head id="Head1" runat="server"> 

 <title></title>
 </head>
 <body>
<form id="form1" runat="server">
<div>
    <asp:Calendar ID="Calendar1" runat="server" Visible="False" OnSelectionChanged="Calendar1_SelectionChanged"></asp:Calendar>
</div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:LinkButton ID="LinkButton1" runat="server" onclick="LinkButton1_Click">PickDate...</asp:LinkButton>
</form>

默认.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
protected void LinkButton1_Click(object sender, EventArgs e)
{
    Calendar1.Visible = true;
}
protected void Calendar1_SelectionChanged(object sender, EventArgs e)
{


    TextBox1.Text = Calendar1.SelectedDate.ToLongDateString();


    Calendar1.Visible = false;

}
}

谢谢

怎么样

protected void TextBox1_TextChanged(object sender, EventArgs e)
{
    Calendar1.SelectedDate = Convert.ToDateTime(TextBox1.Text);
}

 protected void LinkButton1_Click(object sender, EventArgs e)
    {
        if(TextBox1.Text!=string.Empty)
            Calendar1.SelectedDate = Convert.ToDateTime(TextBox1.Text);

        Calendar1.Visible = true;
    }

但是您需要在将文本框值转换为日期时间之前验证用户输入的日期时间。这是javascript日期时间验证的链接。

当文本发生变化时,在文本框上创建一个事件

在事件中检查文本是否是处理异常的实际日期时间

protected void TextBox1_TextChanged(object sender, EventArgs e)
{
  DateTime curDate = DateTime.Now;
  if (DateTime.TryParse(TextBox1.Text, out curDate))
  {
    Calendar1.SelectedDate = Convert.ToDateTime(TextBox1.Text);
  }
}
