Validating 3 fields

[Bilal]

Hi,

 I am trying to build a custom validator to validate 3 fields: Min < Most Likely < Max.

 I've written this custom validator, but for some reason, most of the time, the value of "Max" is being read as null and no error messages are displayed. Is there something wrong with my code:

 Thanks,

Bilal

Hello Bilal,

This happens only when the the validation rule is triggered by a change in the Mid input, which is expected. I am not sure what exactly the expected behavior is, however you could try calling the validate method each time a NumericTextBox is modified, as shown here.

Hi,

The idea is to always make sure that Min is < Med and Med is < Max. Shall I write the validator in a different way? Or, you think calling the validate function every time Min, Med and Max values change would do the job?

 

Thanks

Hello Bilal,

You can try splitting the logic into three rules, each checking only a single input at a time. Calling the validate method is optional of course, but it will help you validate all inputs immediately, no matter which one has changed.
