asp.net中的验证控件 [英] validation control in asp.net

问题描述

如何以格式mm.dd.yyyy

asp.net验证asp.net中文本框中的日期，如果要验证textBox，请尝试此操作

 bool isValid = true;
        尝试
        {
            字符串dt = TextBox1.Text;
            DateTime dateTime = DateTime.ParseExact(dt，"MM.dd.yy"，System.Globalization.CultureInfo.InvariantCulture);
        }
        抓住
        {
            this.Response.Write(输入的无效日期 br  > );
            isValid = false;
        }
        this.Response.Write("isValid:" + isValid +" br  
 

验证日期在所有情况下均无法正常工作.
最好使用提到的格式的ajax日历扩展器...

how to validate date in a textbox in asp.net in format mm.dd.yyyy

解决方案

try this if you want to validate textBox

bool isValid = true;
        try
        {
            string dt = TextBox1.Text;
            DateTime dateTime = DateTime.ParseExact(dt, "MM.dd.yy", System.Globalization.CultureInfo.InvariantCulture);
        }
        catch
        {
            this.Response.Write("Invalid Date entered<br>");
            isValid = false;
        }
        this.Response.Write("isValid: " + isValid + "<br>");

validating the date is will not work properly in all the situations .
its better to use ajax calender extender in that mention the format ...
hope it helps you
