You can see, it has just returned false in the LoadPostData method. Now it has used my
CustomTextBox at my aspx page as

%@ Register TagPrefix="myControl"Namespace="CustomControl" Assembly="CustomControl" %>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">
<myControl:CustomTextBox ID="TextBox1" runat="Server" ValidateRequestMode="Enabled">
</myControl:CustomTextBox><br /?
<asp:Button ID="Button1" runat="server" Text="Submit" OnClick="Button1_Click" />
</asp:Content>
Now set the requestValidationMode as 4.5 in web.config and enter some script tag and submit.
You would not get any error even RequestValidation is enabled. This proves the validation
fires only when data is accessed from the form collection.
