使用ASP.Net验证控件完全满足您的要求:

Use the ASP.Net Validation controls o full fill your requirement:

"CompareValidator"将解决您的问题.
1)添加``CompareValidator''
2)设置以下属性
2.1)ControlToCompare-> textbox1
2.2)ControlToValidate-> textbox2
2.3)ErrorMessage->您的留言在这里
2.4)运算符->小于
2.5)SetFocusonError-> true
2.6)类型->字符串/整数/日期

注意:这仅适用于"LostFocus"，而不能在插入文本框时使用(如果您需要使用javascript).

The ''CompareValidator'' will solve your issue.
1) add the ''CompareValidator''
2) Set the following properties
2.1) ControlToCompare->textbox1
2.2) ControlToValidate-> textbox2
2.3) ErrorMessage-> Your Message goes here
2.4) Operator-> Less than
2.5) SetFocusonError->true
2.6) type-> String/Integet/Date

Note: this is will work only on ''LostFocus'' not while inserting into the textbox(if you want you need to use the javascript).
