    <p>I'm unable to get the string of WebGrid.SortColumn on my webpage. When I'm debugging my Razor page the value is set as shown on the image below. So just before the View is send to my browser something changes from this variable so it seems empty. I need this property to be printed inside the hidden field to add the arrows for the sorting function, however all options I can think of didn't work to get the value inside my page.</p> <p>This code is used inside a partial view _Test.csHtml</p> <pre><code>string sortCol = "testing the sortcolumn " + grid.SortColumn; &lt;p&gt;Here is sortcolumn value :: @sortCol&lt;/p&gt; //displays --&gt; &lt;p&gt;Here is sortcolumn value :: &lt;/p&gt; @Html.Hidden("dir", grid.SortDirection); //displays --&gt; &lt;input id="dir" type="hidden" value="Ascending" name="dir"&gt; @Html.Hidden("col", grid.SortColumn); // displays --&gt; &lt;input id="col" type="hidden" value="" name="col"&gt; </code></pre> <h2>image</h2> <p><img src="https://i.stack.imgur.com/aet4P.png" alt="enter image description here"></p> <p>Thanks in advance, hope everything is clear, if not I will explain myself further</p> <h2>EDIT</h2> <p>the line :: <p>Here is sortcolumn value :: @sortCol</p> </p> <p>output :: <p>Here is sortcolumn value :: testing the sortcolumn </p></p> <p>Which is even more weird, because the variable is filled with the correct data, but just not printing the property....</p> <h2>EDIT 2 (working with viewmodel)</h2> <pre><code>public class InvoicesViewModel : BaseViewModel { public InvoicesViewModel(Controller cntrl) : base(cntrl) { } public InvoicesViewModel() { } public Double subtotal { get; set; } public WebGrid grid { get; set; } public string sortColumn { get; set; } public string help { get; set; } public IOrderedEnumerable&lt;TtCompanyInvoicelist&gt; invList { get; set; } } public ActionResult Index() { vm.grid = new WebGrid(vm.invList, rowsPerPage: 10, ajaxUpdateContainerId: "grid", ajaxUpdateCallback: "webGridUpdated"); vm.sortColumn = vm.grid.SortColumn; return View(vm); } </code></pre> <p><img src="https://i.stack.imgur.com/vPCQc.png" alt="enter image description here"></p> <p><img src="https://i.stack.imgur.com/WJ7Wa.png" alt="enter image description here"></p> <p>In the controller you can see the value of the object is correct. In the view you can see the object is still filled correctly. But the output remains the same, the value of my hidden input is empty.</p>

    1. CODoes the value of `@sortCol` render ok? Generally it's safer to send down a view model with all the data the view needs rather than relying on UI components.

    2. COas you can see on the image the property is filled with a string... So yes it filled correctly, so i guess it renders ok. I have been thinking of creating the webgrid inside my controller and passing it to the viewmodel and then printing the var. Haven't tried it just because i'm curious why I'm getting this situation, been debugging this for a couple of hours now....

    3. COthe only thing I can think of is the view hasn't been initialized by the time the server side code is run. For example, if you take a copy of the value i.e. `@ { var sortCol = grid.SortColumn; }` and then use this instead does it work? e.g. `@Html.Hidden("col", sortCol)`

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).
