解决.net ajax 日期控件 选择时不能显示当前是几点几分
前台代码为：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:TextBox ID="txtDateTime" runat="server" AutoPostBack="True" OnTextChanged="txtDateTime_TextChanged"></asp:TextBox>
<asp:ImageButton ID="ImgBtnDate" runat="server" ImageUrl="~/Images/Calendar_scheduleHS.png" />
<cc1:CalendarExtender ID="CalendarExtender1" runat="server" PopupButtonID="ImgBtnDate"
TargetControlID="txtDateTime">
</cc1:CalendarExtender>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
在后台只需要在textbox的OnTextChanged：
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void txtDateTime_TextChanged(object sender, EventArgs e)
{
this.txtDateTime.Text += DateTime.Now.ToString(" HH:mm");
}
}
要把textbox放在一个updatepanel里面，并且包textbox的AutopostBack的属性设为：true
效果如图：
这样就可以了。。。 呵呵 第一次写博客 写得不好 请多指教……
