Changing the value of Page.IsValid to be False

I have developed an ASP user control that utilizes the jquery UI datepicker to display a standardized calendar on our website.

Currently, I am working on adding validation to this control to avoid having to implement it on every page where the calendar is used. Is there a way to set Page_IsValid to false directly from the ascx file?

Below is the code snippet:

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="jQueryCalendar.ascx.vb" Inherits="Controls_Misc_jQueryCalendar" %>

    <style type="text/css">
        div.ui-datepicker, div.ui-widget {
            font-size: 12px !important;
        }
        img.ui-datepicker-trigger{
            margin-bottom:-5px;
        }
    </style>
    <script type="text/javascript">
        $(document).ready(function () {
            $('.datepicker').datepicker({
                showOn: 'button',
                buttonImage: '<%= Me.ImageURL%>',
                buttonImageOnly: true,
                changeMonth: true,
                changeYear: true,
                showOtherMonths: true,
                selectOtherMonths: true,
                dateFormat: 'dd/mm/yy'
            });
        });            
        </script>

Answer №1

The property known as IsValid is designated as read-only, meaning it cannot be altered. To rectify this issue, consider incorporating a validator-control within your user control!

I've noticed that your user control currently lacks the text-input required for the datepicker, opting instead to apply the datepicker to all elements belonging to the datepicker class. I recommend revising this approach by including a TextBox within the usercontrol, allowing you to attach a validator control to it.
