    [CLOSED] textarea with validator

    I have a hidden textarea in a formpanel, the textarea is displayed when a checkbox is ticked.

    The textarea has a validator attached to it that returns a message if the textarea is blank and the checkbox is ticked.

    The validator event is fired when the page loads but it is not called again, for example on blur or when the save button is clicked.

    Could you please advise me how to validate the control?

    Below is a sample form

    RE: [CLOSED] textarea with validator

    Hi,

    Validator property expects function name
    Validator="validateFreeCourse"
    I am not sure why do you expect to run that validator on Save click. You have to check form panel validity manual
    Please see the following sample
    <%@ Page Language="C#" %>

                {
                    if (chkFreeCourse.Checked == false)
                    {
                        lblFreeCourseCommentsLabel.Hide();
