One asp.net validator for several TextBoxes

I have 3 TextBoxes on the page. How do I setup one validator (and what's kind of validator?) to validate each of TextBoxes on client side?开发者_如何学C

First textBox must contains only 1-3 number of digits, second - infinite number of digits, third - 0-5 number of digits

It would be better to use different validators for different text boxes. Use 3 validators for each with display message as * sign.

Then use Validation Summary control to print a single message for all of them, as you want a single message to be displayed for all. Refer this link: MSDN Validation Summary

Check this too: Validation Summary to work with client-side validations

Your expressions would be along the lines of:

[0-9]{1,3}

[0-9]+

[0-9]{0,5}

Updated following further info:

You could combine the values from each text box into a comma separated value and then validate that using [0-9]{0,3},[0-9]+,[0-9]{1,5} expression.

Either use javascript to copy the value into a hidden textbox field with it's own regex validator using above expression, or just perform the validation manually.

e.g. Using jquery

 $('#hiddenCombinedField').val($('#field1').val()+','+$('#field2').val()+','+$('#field3').val());

Run this just before you call validate on the form.

You could use a CustomValidator but i would prefer using three distinct validators, one for every TextBox.

It's possible to leave the ControlToValidate-property of the CustomValidator empty. On this way you can validate multiple controls at the same time.
