Set Required Field Validator from .ASPX page

I am trying to set the enable attribute on a required field validator control from a function in my code behind. The below code seems to not be working. What am I missing? I am doing this so I can test my code behind validation and not have to go to all required field validator controls to change the enable property to false etc. 

            <asp:RequiredFieldValidator ID="rfvRadTxtTimerName" 
                runat="server" ForeColor="Red"
                ControlToValidate="txtTimerName"
                ErrorMessage="* Email Address is a required field."
                ValidationGroup="submitTimer"
                Enabled=<%# (EnableOrDisableRequiredValidators() == true ? true : false) %>
                Display="Dynamic" >
            </asp:RequiredFieldValidator>


    protected bool EnableOrDisableRequiredValidators()
    {
        return false;
    }

<asp:RequiredFieldValidator ID="rfvRadTxtTimerName" 
    runat="server" ForeColor="Red"
    ControlToValidate="txtTimerName"
    ErrorMessage="* Email Address is a required field."
    ValidationGroup="submitTimer"
    Display="Dynamic">
</asp:RequiredFieldValidator>

Meanwhile somewhere in code behind: 

rfvRadTxtTimerName.Enabled = false // true?

I'm not 100% sure, but I think it has to do with data binding and when controls values are initialized.

As an aside, this line (if you found a way to make it work)

Enabled=<%# (EnableOrDisableRequiredValidators() == true ? true : false) %>

could be cleaned up

Enabled=<%# EnableOrDisableRequiredValidators() %>
