海友我在Asp.Net上有关于Ajax Calander控制的问题

问题描述：

实际上在我的网页表单中有三个文本框，比如

txtdt1（ajaxcalnder1），txtdt2（ajaxcalender2），txtnum3

如果用户选择'txtdt1'中的任何日期。

'txtdt2'必须小于'txtdt1'并且自动天数之间的差异必须显示在'txtnum3'中

...

如何为此写javascript

这些是服务器端控制

请告诉我...

Actually in my Web Form Three Textbox like

txtdt1(ajaxcalnder1),txtdt2(ajaxcalender2),txtnum3

if user select any date in 'txtdt1'.
'txtdt2' must be less then the 'txtdt1' and automatically the difference between days are must be displayed in 'txtnum3'
...
how to write javascript for this

and those are server side conrolls

please tell me...

答

使用JavaScript：calculating-the-difference-between-two-dates-in-javascript.html [ ^ ]

使用C＃：

With JavaScript : calculating-the-difference-between-two-dates-in-javascript.html[^]

With C#:

private void CalculateDateDifference()
{
    TimeSpan i = new TimeSpan(0, 0, 0);
    DateTime startDate = Convert.ToDateTime(this.txtStartDate.Text.Trim(), new CultureInfo("en-us"));
    DateTime endDate = Convert.ToDateTime(this.txtEndDate.Text.Trim(), new CultureInfo("en-us"));
    i += endDate.Subtract(startDate);
    int days = i.Days;
    this.lblDays.Text = "Total Days : " + days.ToString();
}
