根据文本框中的日期选择计算天数 [英] Calculate no of days on basis of date selection in textbox

问题描述

大家好，



我在两个文本框上有两个ajax日历控件，作为开始日期和结束日期，并且有一个Label.Now，这是因为用户输入在endate文本框上选择日期时的开始日期和结束日期应该很快就会在Label.I中使用onblur结束日期事件，但它在选择完成日期之前触发，并且错误以无效形式生成日期。



如果你有人提供其他解决方案，请告诉我。



感谢你

推荐答案

试试这个





在结束日期_文本更改于编码方



DateTime sDateTime = Convert.ToDateTime（startdate.Text）;

DateTime eDateTime = Convert.ToDateTime（enddate.Text）;

System.TimeSpan span = eDateTime - sDateTime;

int ddays =（int）span.TotalDays;

label.Text = ddays.ToString （ ）;

try this one


at end date_Text Changed at coding side

DateTime sDateTime = Convert.ToDateTime(startdate.Text);
DateTime eDateTime = Convert.ToDateTime(enddate.Text);
System.TimeSpan span = eDateTime - sDateTime;
int ddays = (int)span.TotalDays;
label.Text=ddays.ToString();

为什么不使用Calendar控件？这样你总是有一个合理的约会，并且用户不会犯错并以错误的格式输入...

MSDN [ ^ ]

Why not use a Calendar control instead? That way you always have a sensible date, and the user can't make a mistake and enter it in the wrong format...
