Tricky Control Validation Issue

[Mark Sandfox]

I have a tricky control validation issue. I have probably designed this the
wrong way but here is what I have.

I have 6 TextBoxes; tbPN, tbA, tbC, tbS, tbZ, tbDOB and there are 20 of each
with a corresponding number following the names. (Couldn't get ASP.NET to
recognize a control array)

The question is: How do I get the tbA, tbC, tbS, tbZ, & tbDOB to be
required if (AND ONLY IF) tbPN has text? I have tried in the past to get
VBScript to intertwine with ASPX but to no avail. I must be missing the
bigger picture here. Thank you in advance for your help and guidance.

Have you looked into custom validators?

Microsoft's predefined validators do not know how to sense a value in
another control before enabling themselves.

A custom validator will let you write this but you have to recreate the
logic of the original validator that you are replacing, including on the
client-side.

I build a replacement to Microsoft's validators designed to get the job
done, even difficult tasks like this. "Professional Validation And More"
(http://www.peterblum.com/vam/home.aspx) includes 22 validators. All have a
new property, Enabler, where you setup a rule that enables them. In your
case, the rule is to check if tBPN has text. It supports client-side
validation on many more browsers too, not just IE and IE/Mac.

Even if you aren't looking for a replacement, it helps to know the
limitations of the controls you are using to make better design decisions. I
put together a list at http://www.peterblum.com/vam/valmain.aspx.
