RequiredField Validator question

[Guest]

Hi,
I have a TextBox control that needs to have a value only if a drop down box
on the same page has a certain value selected. Is it possible to achieve this
using RequiredFieldValidator for the TextBox and having EnableClientScript =
true (without a post)?

Thank you

Hi, although this could be accomplished with Custom Validators, the best
practice is probably to write the javascript validation yourself.

Hope that helps,

I tried to do this with Custom Validators, but it does not fire if the
textbox it validates is empty. So I need to define a RequiredFieldValidator
for the same textbox, but it has to be enabled only if a certain value is
selected in a dropdown list.

Vi,

you certainly can You can use ValidatorEnable to enable or disable any
validators on your page.
Basically it vorks like this:

ValidatorEnable(document.getElementById("yourValidator"), false);
or
ValidatorEnable(document.getElementById("yourValidator"), true); // what
a surprise ;-)
