    <p>I have a vb.net MVC3 application using RAZOR views. Some of the functions take a long time to complete due to the fact that they are compiling data from the database. During this long wait the browser screen is white and there is no sign that it is doing whats its supposed to other than the activity ring. What I would like to do is create a progress bar, use some simple math on the count method to determine the progress bar percent complete and show this on the screen instead of the plain white browser screen.. I am certain that I would need to do this with a Jquery widget of some sort. And have looked all over google but nothing seems to be hitting on what I am needing here.. The controller function that is called when the White screen is displayed until it is finished is below:</p> <pre><code> Function beginArchive() Dim cList As List(Of cours) = db.courses.ToList For Each x In cList Dim indCourse = x Dim courHfile As String = archiveFiles(x.course_id) Dim arcCourse As New archive arcCourse.cDesc = indCourse.course_description If Not String.IsNullOrEmpty(courHfile) Then arcCourse.cHandouts = courHfile End If arcCourse.cHours = indCourse.course_hours arcCourse.conNum = Convert.ToInt16(indCourse.courseNum) arcCourse.cPre = indCourse.course_prefix arcCourse.cRef = indCourse.course_ref arcCourse.cSpeaker = indCourse.course_speaker arcCourse.cTitle = indCourse.course_title db.archives.AddObject(arcCourse) db.SaveChanges() Dim testSuccess As Integer = delOldFiles(indCourse.course_id) Next Return RedirectToAction("Index", "Admin") End Function </code></pre> <p>Razor View is this:</p> <pre><code>@Code ViewData("Title") = "Archive Previous Conf. Handouts" End Code &lt;fieldset&gt; &lt;h2&gt;You are about to archive all handouts from last years conference. If you continue all of those handouts will be moved to the archive&lt;/h2&gt; &lt;div id="sidebar3"&gt; &lt;p&gt; @Html.ActionLink("Begin Archive", "beginArchive","handoutArchive") @Html.ActionLink("Back to Admin Tools", "Index", "Admin") &lt;/p&gt; &lt;/div&gt; &lt;/fieldset&gt; </code></pre> <p>Any ideas on how I would go about adding a simple progress bar to this which I am assuming would have to be fired by the controller itself...</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).
