    <p>What cool functionality and methods do <strong><em>you</em></strong> add to your ASP.net <code>BasePage : System.Web.UI.Page</code> classes?</p> <h2>Examples</h2> <p>Here's something I use for authentication, and I'd like to hear your opinions on this:</p> <pre><code>protected override void OnPreInit(EventArgs e) { base.OnPreInit(e); // Authentication code omitted... Essentially same as below. if (_RequiresAuthentication &amp;&amp; !(IsAuthorized)) { RespondForbidden("You do not have permissions to view this page.", UnauthorizedRedirect); return; } } // This function is overridden in each page subclass and fitted to each page's // own authorization requirements. // This also allows cascading authorization checks, // e.g: User has permission to view page? No - base.IsAuthorized - Is user an admin? protected virtual bool IsAuthorized { get { return true; } } </code></pre> <p>My BasePage class contains an instance of this class:</p> <pre><code>public class StatusCodeResponse { public StatusCodeResponse(HttpContext context) { this._context = context; } /// &lt;summary&gt; /// Responds with a specified status code, and if specified - transfers to a page. /// &lt;/summary&gt; private void RespondStatusCode(HttpContext context, System.Net.HttpStatusCode status, string message, string transfer) { if (string.IsNullOrEmpty(transfer)) { throw new HttpException((int)status, message); } context.Response.StatusCode = (int)status; context.Response.StatusDescription = message; context.Server.Transfer(transfer); } public void RespondForbidden(string message, string transfer) { RespondStatusCode(this._context, System.Net.HttpStatusCode.Forbidden, message, transfer); } // And a few more like these... } </code></pre> <p>As a side note, this could be accomplished using extension methods for the <code>HttpResponse</code> object.</p> <p>And another method I find quite handy for parsing querystring int arguments:</p> <pre><code>public bool ParseId(string field, out int result) { return (int.TryParse(Request.QueryString[field], out result) &amp;&amp; result &gt; 0); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
