European ASP.NET 4.0 Hosting :: Error Message - A potentially dangerous Request.QueryString value was detected from the client

clock May 13, 2011 07:26 by author Scott

For those of you who just upgraded your site to the latest ASP.NET 4.0 Framework, you may sometimes see this error message: “A potentially dangerous Request.QueryString value was detected from the client”.

The request validation feature in ASP.NET provides a certain level of default protection against cross-site scripting (XSS) attacks. In previous versions of ASP.NET, request validation was enabled by default. However, it applied only to ASP.NET and only when those pages were executing.

In ASP.NET 4, by default, request validation is enabled for all requests, because it is enabled before the BeginRequest
phase of an HTTP request. As a result, request validation applies to requests for all ASP.NET resources, not just .aspx page requests. This includes requests such as Web service calls and custom HTTP handlers. Request validation is also active when custom HTTP modules are reading the contents of an HTTP request.

As a result, request validation errors might now occur for requests that previously did not trigger errors. To revert to the behavior of the ASP.NET 2.0 request validation feature, add the following setting in the Web.Config  file:

<httpRuntime requestValidationMode="2.0" />

However, we recommend that you analyze any request validation errors to determine whether existing handlers, modules, or other custom code accesses potentially unsafe HTTP inputs that could be XSS attack vectors.

If you have problem with this upgrade, you can host your site with us. We are the premier European hosting that support ASP.NET 4 hosting with only €3.00/month. If you don’t like our service, you can just cancel your account.

European ASP.NET 4.0 Hosting :: How to Trigger the Client-side Validation Manually

clock May 10, 2011 06:10 by author Scott

By default the client-side validation is triggered when submitting forms using buttons. However, sometimes you may want to trigger client-side validation on your ASP page manually from custom Javascript. You can achieve that by calling Javascript validation functions provided by the ASP.Net framework directly from your custom code.

The following page source example displays a
TextBox and its validation controls (RequiredFieldValidator & ValidationSummary). The validation controls have the same ValidationGroup defined, which allows us to validate different page elements independently. The page displays also a DIV
element that will cause the Validation action when clicked:

<!-- Validation Summary -->
<asp:ValidationSummary ID="ValidationSummary1" runat="server"
            HeaderText="Validation errors:" ValidationGroup="Group1"/> 

<!-- TextBox and its validator -->
Name: <asp:TextBox ID="TextBox1" runat="server" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
            ErrorMessage="Name is required" Text="*"
            ControlToValidate="TextBox1" ValidationGroup="Group1"> /> 

<!-- Div that causes client-side validation when clicked -->
<div onclick="Validate();" >Validate Form</div>

The code above should should produce smth like that when validation is triggered:

Now let's take a look at the custom JS code that triggers the validation. There are couple ways to do that:

- Easy way - works for all validators from the same ValidationGroup:

function Validate()
    // If no group name provided the whole page gets validated


- If you want to validate only specific validators:

function Validate()

    // Get the specific validator element
    var validator = document.getElementById('RequiredFieldValidator1');

     // Validate chosen validator

    // Update validation summary for chosen validation group

European ASP.NET 4.0 Hosting :: Sending Email from ASP.Net 4 - C# Sample

clock May 6, 2011 07:15 by author Scott

Below is sample code showing how to send email from ASP.Net 4 (currently in beta as of this posting) using C#. With this code I am assuming that the server already has a local SMTP service installed, so I use "localhost" to relay the email.

Here is the SendMail.aspx page:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="SendMail.aspx.cs" Inherits="SendMail" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">

<html xmlns="">
<head runat="server">
    <form id="form1" runat="server">
        Message to:
        <asp:TextBox ID="txtTo" runat="server"></asp:TextBox>
        <br />
        Message from:
        <asp:TextBox ID="txtFrom" runat="server"></asp:TextBox>
        <br />
        <asp:TextBox ID="txtSubject" runat="server"></asp:TextBox>
        <br />
        Message Body:
        <br />
        <asp:TextBox ID="txtBody" runat="server" Height="171px" TextMode="MultiLine"
        <br />
        <asp:Button ID="Btn_SendMail" runat="server" onclick="Btn_SendMail_Click"
            Text="Send Email" />
        <br />
        <br />
        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

Here is the source code of the SendMail.aspx.cs page:

using System;
using System.Web.UI.WebControls;
using System.Net.Mail;

public partial class SendMail : System.Web.UI.Page

    protected void Btn_SendMail_Click(object sender, EventArgs e)
        MailMessage mailObj = new MailMessage(
            txtFrom.Text, txtTo.Text, txtSubject.Text, txtBody.Text);
        SmtpClient SMTPServer = new SmtpClient("localhost");
            catch (Exception ex)
            Label1.Text = ex.ToString();

Hope this tutorial can help!!
