    <p>This is my VS solution:</p> <pre><code>Core Library - contains Controllers Project A - references Core Project B - references Core </code></pre> <p>Both projects have routing based on the referenced Core Library. However, I want to override certain Controller functions based on which project (a.k.a. "site") is calling the function. I've tried creating Project B Controller that inherits from Core Library Controller, making the Core function virtual and setting the Project B Controller function to "overrides". However, the Project B Controller was never even called.</p> <p>Is this possible? How can I have the Core Controller functions be overridden by the Projects?</p> <p>UPDATE: Post is updated based on comments below, but still not sure why this won't work in MVC.</p> <p>Here is the code for the controller in Project B:</p> <pre><code>public class BaseController : Controller { public StateLevelViewModel GetStateLevelLandingResults(string State, int level) { var data = GetStateCityBreakdown(stateAbbrev, level); } public virtual List&lt;StateCityBreakdownModel&gt; GetStateCityBreakdown(string stateAbbrev, int level) { return db.Database.SqlQuery&lt;StateCityBreakdownModel&gt;("GetCountsByStateAndCity @state, @level", new SqlParameter("state", stateAbbrev), new SqlParameter("level", level)).ToList(); } } public class BaseController : XYZ.Controllers.BaseController { public override List&lt;StateCityBreakdownModel&gt; GetStateCityBreakdown(string stateAbbrev, int level) { return db.Database.SqlQuery&lt;StateCityBreakdownModel&gt;("GetCountsByStateAndCityForPartnership @state, @level, @partner", new SqlParameter("state", stateAbbrev), new SqlParameter("level", level), new SqlParameter("partner", 2)).ToList(); } } </code></pre> <p>UPDATE 2 : inheriting controller is just plain ignored. Issue is that project won't recognize the controller at all.</p>

    1. COAre you using any Dependency Injection container and if yes, did you check if there is any defined controller registration pointing to the base controller, always? Does rest of the actions methods (non-overrides or child controller specific) are being called/invoked properly when you hit the controller?

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).
