I found a tool where i can draw asp.net charts with this free control.

URL: http://www.carlosag.net/

Sample Code:

PieChart chart = new PieChart();
    chart.DataSource = GetDataSet().Tables[0].DefaultView;
    chart.DataXValueField = “Title”;
    chart.DataYValueField = “Price”;
    chart.DataLabels.Visible = true;
    chart.DataLabels.ForeColor = System.Drawing.Color.Blue;
    chart.Shadow.Visible = true;
    chart.DataBind();
    chart.Explosion = 10;
    ChartControl1.Charts.Add(chart);
    ChartControl1.RedrawChart();

Sometimes, you will be migrating your application from a typical ASP.NET into the microsoft supported ASP.NET AJAX Web Extension along with AJAX Control Toolkit. I often get the same issue where i forget to add the httpHandlers and httpModules. Please visit this blog for a quick solution for this issues. It worked for me.

ASP.NET 1.0 introduced the Forms Authentication feature to allow developers to easily author ASP.NET applications that rely on an authentication mechanism they could control. Forms Authentication exposed a set of APIs that developers can simply call to authenticate the user, such as

FormsAuthentication.RedirectFromLoginPage(Username.Text, False)

Forms Authentication in ASP.NET 1.0 would then take the username, encrypt it, and store it within an HTTP cookie. The cookie would be presented on subsequent requests and the user automatically reauthenticated.

One of the common feature requests the ASP.NET team continually received was the ability for Forms Authentication to support cookieless authentication, that is, to not require an HTTP cookie. This is just what the team has provided in ASP.NET 2.0.

Enabling Cookieless Forms Authentication

Cookieless Forms Authentication is enabled within the machine.config file or the web.config file of your application by setting the new cookieless attribute.

Default Configuration for Forms Authentication

<configuration>
  <system.web>
    <authentication mode="Forms">
      <forms name=".ASPXAUTH"
             loginUrl="login.aspx"
             protection="All"
             timeout="30"
             path="/"
             requireSSL="false"
             slidingExpiration="true"
             defaultUrl="default.aspx"
             cookieless="UseCookies" />
    </authentication>
  </system.web>
</configuration>

The cookieless attribute has four possible values:

• UseUri: Forces the authentication ticket to be stored in the URL.
• UseCookies: Forces the authentication ticket to be stored in the cookie (same as ASP.NET 1.0 behavior).
• AutoDetect: Automatically detects whether the browser/device does or does not support cookies.
• UseDeviceProfile: Chooses to use cookies or not based on the device profile settings from machine.config.
