I have the following line of code:

<script type="text/javascript">
            window.onload = function () {
                document.getElementById("<%= chkEmailUpdates.ClientID %>").onchange = function () {
                    var txtAddress = document.getElementById("<%= txtAddress.ClientID %>");
                    txtAddress.disabled = !this.checked;
                    if (!this.checked) txtAddress.value = "";
                    if (this.checked) txtAddress.focus();
                    txtAddress.setAttribute('CausesValidation = " + txtAddress """');
                }
            }
</script>
to enables or disables txtAddress based on the value of a chkEmailUpdates.

Question: How can have txtAddress to be validated only when it is enabled?

Thank you.

Followings are the tags for the check box and txtAddress:

            <tr>
                <td class="style14">
                    Monthly updates?</td>
                <td class="style13">
                    &nbsp;</td>
                <td class="style6">
               
                    <asp:CheckBox ID="chkEmailUpdates" runat="server" Text="Email me updates"  />
                    
                </td>
            </tr>
            <tr>
                <td class="style14">
                    Email Address:</td>
                <td class="style13">
                    <asp:RequiredFieldValidator ID="requireEmail" runat="server" 
                        ControlToValidate="txtAddress" CssClass="style8" 
                        ErrorMessage="Email is required." Display="Dynamic" ValidationGroup="updateRequestEmail" >*</asp:RequiredFieldValidator>
                    <asp:RegularExpressionValidator ID="validEmail" runat="server" 
                        ControlToValidate="txtAddress" 
                        ErrorMessage="Acceptable format is: name@domain.com" 
                        ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" 
                        Display="Dynamic">*</asp:RegularExpressionValidator>
                    </td>
                <td class="style6">
                    <asp:TextBox ID="txtAddress" runat="server"  
                        placeholder="Email required w/ update request only" Width="230px" 
                        Enabled ="false"></asp:TextBox>
                </td>
            </tr>
and
   
Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
.
.
            txtAddress.Enabled = chkEmailUpdates.Checked
            ' If chkEmailUpdates.Checked Then Page.Validate("updateRequestEmail")
.
.
    End Sub
