    <p>I have a few filters for table data represented by dropdowns, but the table data is really huge and the process hangs for a few minutes until the complete table is rendered; only then is the table presented and I can use those filters. </p> <p>I want to be able to access the filters before presenting the data; I don't want to wait for the table to load. This could be done by separating the filters into another view/controller, but I want to handle inside the <code>index()</code> method. </p> <p>I tried to delete the part where the process checks if filters are set, but then than it will work if I set all filters only.</p> <p>Relevant code:</p> <pre><code>Function Index(SelectedTimeType As System.Nullable(Of Integer), SelectedTimeStatus As System.Nullable(Of Integer), SelectedProject As System.Nullable(Of Integer), SelectedTask As System.Nullable(Of Integer)) As ActionResult Dim tipovi = unitOfWork.TimeTypeRepository.Get(orderBy:=Function(q) q.OrderBy(Function(d) d.Opis)) ViewBag.SelectedTimeType = New SelectList(tipovi, "TimeTypeID", "Opis", SelectedTimeType) Dim statusi = unitOfWork.TimeStatusRepository.Get(orderBy:=Function(q) q.OrderBy(Function(d) d.Opis)) ViewBag.SelectedTimeStatus = New SelectList(statusi, "TimeStatusID", "Opis", SelectedTimeStatus) Dim projekti = unitOfWork.ProjectRepository.Get(orderBy:=Function(q) q.OrderBy(Function(d) d.Opis)) ViewBag.SelectedProject = New SelectList(projekti, "ProjekatID", "Opis", SelectedProject) Dim taskovi = unitOfWork.TaskRepository.Get(orderBy:=Function(q) q.OrderBy(Function(d) d.Opis)) ViewBag.SelectedTask = New SelectList(taskovi, "TaskID", "Opis", SelectedTask) Dim timeTypeID As Integer = SelectedTimeType.GetValueOrDefault() Dim timeStatusID As Integer = SelectedTimeStatus.GetValueOrDefault() Dim projekatID As Integer = SelectedProject.GetValueOrDefault() Dim taskID As Integer = SelectedTask.GetValueOrDefault() Return View(unitOfWork.TimeTrackingRepository.Get( filter:=Function(d) Not (SelectedTimeType.HasValue And SelectedTimeStatus.HasValue And SelectedProject.HasValue And SelectedTask.HasValue) OrElse (d.TimeTypeID = timeTypeID And d.TimeStatusID = timeStatusID And d.ProjectID = projekatID And d.TaskID = taskID), orderBy:=Function(q) q.OrderBy(Function(d) d.TimeTrackingID))) End Function </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.

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