    <p>I'm building an Iframe canvas application for Facebook. I'm not using the Javascript SDK.</p> <p>This is the code I'm using, and it works well in all browsers except for Safari.</p> <pre><code>protected FacebookApp app; </code></pre> <p>protected CanvasAuthorizer cauth;</p> <p>Response.AddHeader("p3p", "CP=\"IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT\""); app = new FacebookApp(); cauth = new CanvasAuthorizer(app); if (!cauth.IsAuthorized()) { myAuth auth = new myAuth(); myAuth.Authorize(app, Request, Response, perms); }</p> <pre><code> if (cauth.Authorize()) { </code></pre> <p>// Do my app stuff here }</p> <pre><code>public class myAuth { public static void Authorize(FacebookApp fbApp, System.Web.HttpRequest request, System.Web.HttpResponse response, string perms) { Authorize(fbApp, request, response, perms, null); } public static void Authorize(FacebookApp fbApp, System.Web.HttpRequest request, System.Web.HttpResponse response, string perms, string redirectUrl) { Uri url = fbApp.GetLoginUrl(); NameValueCollection nvc = System.Web.HttpUtility.ParseQueryString(url.Query); if (!string.IsNullOrEmpty(perms)) nvc.Add("req_perms", perms); if (!string.IsNullOrEmpty(redirectUrl)) nvc["next"] = GetAppRelativeUrl(redirectUrl); else if (request.QueryString.Count &gt; 0) nvc["next"] = GetAppRelativeUrl(request.Path.Replace(request.ApplicationPath, string.Empty).Replace(request.ApplicationPath.ToLower(), string.Empty) + "?" + request.QueryString); else nvc["next"] = GetAppRelativeUrl(request.Path.Replace(request.ApplicationPath, string.Empty).Replace(request.ApplicationPath.ToLower(), string.Empty)); UriBuilder ub = new UriBuilder(url); ub.Query = nvc.ToString(); string content = CanvasUrlBuilder.GetCanvasRedirectHtml(ub.Uri); response.ContentType = "text/html"; response.Write(content); response.End(); } public static string GetAppRelativeUrl(string url) { return CanvasSettings.Current.CanvasPageUrl.ToString(); } } </code></pre> <p>I read about Safari not allowing third party cookies, and I figure that's where the problem lies. My question is wheter there's a way to handle this using the SDK, or what my options are.</p> <p>Regards, Anders Pettersson</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
