    <p>I have a page in one of my ASP.NET applications (VB) that relies on a 3rd party service being live, and I'm using jQuery to display an overlay if this service is found to be down. I've been using the same approach for other warnings in the app - the difference with this one is that it needs to redirect after the user clicks the button on the warning popup to remove the overlay. For some reason I'm getting the error "Error: The value of the property 'warn_redirect' is null or undefined, not a Function object."</p> <p>Any assistance is greatly appreciated! My code follows:</p> <p>jQuery</p> <pre><code>function warn_redirect(msg, title, nextpage) { // show modal div //alert(obj.id); $("html").css("overflow", "hidden"); $("body").append("&lt;div id='popup_overlay'&gt;&lt;/div&gt;&lt;div id='popup_window'&gt;&lt;/div&gt;"); $("#popup_overlay").addClass("popup_overlayBG"); $("#popup_overlay").fadeIn("slow"); // build warning box $("#popup_window").append("&lt;h1&gt;" + title + "&lt;/h1&gt;"); $("#popup_window").append("&lt;p id='popup_message'&gt;&lt;center&gt;" + msg + "&lt;/center&gt;&lt;/p&gt;"); $("#popup_window").append("&lt;div class='buttons'&gt;&lt;center&gt;&lt;button id='continue' class='positive' type='submit'&gt;OK&lt;/button&gt;&lt;/center&gt;&lt;/div&gt;"); // attach action to button $("#continue").click(popup_remove_redirect(nextpage)); // display warning window popup_position(400, 300); $("#popup_window").css({ display: "block" }); //for safari using css instead of show $("#continue").focus(); $("#continue").blur(); } function popup_remove_redirect(nextpage) { $("#popup_window").fadeOut("fast", function () { $('#popup_window,#popup_overlay').trigger("unload").unbind().remove(); }); $("body", "html").css({ height: "auto", width: "auto" }); $("html").css("overflow", ""); window.location.href = nextpage; </code></pre> <p>}</p> <p>Here is the VB.NET calling code:</p> <pre><code>If Status = "DOWN" Then Dim clsUtility As New Utility clsUtility.Emailer("email@company.com", "email@company.com", "", "", "The Service Is Down!", "Please investigate") Dim ScriptString As String = "&lt;script language='javascript'&gt;" ScriptString += "warn_redirect('Some warning message.', 'Warning', 'AnotherPage.aspx');" ScriptString += "&lt;/script&gt;" ClientScript.RegisterStartupScript(Me.GetType, "warnscript", ScriptString) 'Response.Redirect("AnotherPage.aspx?ID=" &amp; Session("SelKey") &amp; "&amp;UN=" &amp; Header1.UserNumber) //this didn't work either End If </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.
