服务器端验证为假时如何防止代码执行 [英] How to prevent execution of code when server side validation false

问题描述

我有一个插入数据库记录的按钮，还有一个customeValidation函数来检查fromDate和toDate的dateDifference必须少于31天.所以我这样写了custCheckDates_ServerValidate事件.

I have a button to inser records in database and a customeValidation function to check the fromDate and toDate''s dateDifference must be less than 31 days. So I writted custCheckDates_ServerValidate event like this.

DateTime dt1 = new DateTime(year,month, day);
DateTime dt2 = new DateTime(year1, month1, day1);
TimeSpan diffRes = dt2.Subtract(dt1);
if (diffRes.Days > 31)
{
args.IsValid = false;
return;
}
else
args.IsValid = true;

它工作正常，但是当验证为false时，它会显示错误消息，但还会在数据库中插入记录.

因此，如果验证为假，如何停止在数据库中插入记录的执行.我知道，如果我使用ClientSideValidationFunction，然后编写"return false"将其停止，但我希望它在服务器端.

It''s working fine but when validation false it displays error msg but also insert records in the database.

So how I can stop the execution of inserting records in database if validation is false. I know that if I use ClientSideValidationFunction then writting ''return false'' stop it but I want it server side.

推荐答案

您可以使用 Page.IsValid [

Hi,

You can use Page.IsValid[^] property to check if validation succeed. if it returns false then you should not insert your record in database.

So this property will be checked before insert function.
