Validation Suggestions??

[Guest]

This is a hard one for me, I am fairly new to C#/ASP.net and need some
suggestions!

I have 3 controls on a page, if control 'ivtshp' has a value it is valid and
requires 'ivrng' to have a value.

And if 'ivsurvnum' has a value then it is valid.

But ivtshp/ivrng and ivsurvnum can't both be valid.

So I need to validate ivtshp to say you must enter a valid number in ivrng,
I need to validate ivrng saying you must enter a valid number in ivtshp, and
I need to validate ivsurvnum saying you can't have a surv only and t/r search
at the same time.

Suggestions or Idea's????

Sounds like you need a custom validation process. It could be either client-
or server-side. Whatever is most appropriate for your app.

Hi Dewright,

As Kevin has mentioned, in ASP.NET we can perform user input validation for
controls through both clientside and serverside code. If you're wantting to
use ASP.NET's validation control to check the entry fields, we may need to
use custom validator if the validation logic is a bit complex. Otherwise,
we can just embeded our validation code in the page's codebehind code to do
the work as we expected. What's your current plan?

What I did end up doing is writing a series of if/else if/else functions in
my page submit function to loop through all of my box's.

I will next look at how to use this function with custom validators but at
this time this worked great.

The built-in ASP.Net validation Controls are quite fine for most tasks.
However, when you get into a complex situation, you might spend as much time
getting them to work properly as you would "rolling your own" validation.
So, it sounds to me like (as Uncle Chutney would say ) you've hit the money
right on the head. ;-)

There are many shortcomings to Microsoft's validators that force people to
write custom code. In your case, you will write a custom validator to handle
the logic.

I built a replacement to Microsoft's validators that addresses its
limitations called Professional Validation And More
(http://www.peterblum.com/vam/home.aspx). In your case, you will find that
each of its 25 validators has a property called Enabler where you setup a
rule that automatically enables the validator based on other conditions on
the page, like the RequiredTextValidator for 'ivrng' uses the Enabler to
monitor the text in 'ivtshp'.
