disable validation depending on option

I have 2 option buttons and a submit button. A comment(a text box) must be provide if option A is selected. How can I disable the validation when Option B is selected?

I read on http://msdn.microsoft.com/en-us/library/aa479045.asp that you can override the Validate method of the Page and switch it off from there but that didn't seem to work for me, didn't go into my break point.

C#

protected override void Validate()
{
    this.rfvComment.Enabled = this.optDecline.Checked;
    base.Validate();
}

Does anyone have any ideas how I can achieve this or why the above code isn't working?

Hi,

Enable or Disable ASP.Net Validation on client side
rfvOther: is a Required Field Validator

XML

//Syntax:
ValidatorEnable(ValidatorContronName,Boolean);
//Explanation:ValidatorContronName – This is ClientID of the Validation control.
Boolean - true(Enable) / false(Disable)
//Example:
ValidatorEnable(document.getElementById('<%=rfvOther.ClientID%>'), fale);

You can implement this function according you logic.

Please do let me know, if you have any doubt.
