3.6使用CompareValidator控件
使用CompareValidator控件
三种不同类型的验证任务
1、执行数据类型检测 验证输入是否类型正确的值
2、输入值和一固定值进行比较
3、一表单值与另一表单值进行比较
六属性：
ControlToValidate
Text
Type String Integer Double Date Currency
Operator 所执行的比较类型 可能的值：DataTypeCheck Equal GreaterThan GreaterThanEqual LessThan LessThanEqual和NotEqual
ValueToCompare 所比较的固定值
ControlToCompare 所比较的控件的ID
