The Simple Answer to the WebGrid sorting issue - LINQ to Entities only supports casting EDM primitive or enumeration types

-
Spent so much time on this error, examining my models, data structure etc. What it boiled down to was the sortability of the IEnumerable object on the page vs a sortable list. All you need to do most of the time is to recast it in your controller like this:

 var retdata = bl.GetPidHistory(pid);
 var itemstoreturn = retdata.ToList();
 return View(itemstoreturn);

 This is applicable when your view has a model like this: @model IEnumerable

Sticky Footer made simple

-
CSS Footers are simple but people tend to overthink them.  Here is how it works You have two pieces A container that all your other stuff is in A footer that you want to always stay at the bottom of the page In Blazor I put this container on my content pages and not my host page because I didn't want my left hand nav to be involved <div class="container"> All my content </div> <footer> Centered footer content </footer> And the CSS .container {     width:100%;     padding: 0 15px; } footer {     font-size: 12px; (you could also use a vw value here)     padding-top:20px;     background-color: #xxx;     color: #fff;     margin: auto;     height: 60px;     width: 100%;     position: sticky; //absolute;     bottom: 0;     text-align: center; }
