Does the ASP.NET main route tag helper use Route?
I am confused about how the asp-route- * tag helper works. I understand this has something to do with the routing I have installed. For example.
routes.MapRoute(
name: null,
template: "{category}/Page{page:int}",
defaults: new { controller = "Product", action = "List" }
);
Here I am displaying my route like this: / Category / PageNumber for the List action in the Product controller
The following code will, when clicked, follow the previous screen
<a class="btn btn-block
@(cat == ViewBag.SelectedCategory ? "btn-primary" : "btn-default")"
asp-controller="Product"
asp-action="List"
asp-route-category="@cat"
asp-route-page="1">@cat</a>
So as I understand it, "asp-route-category" will look for "{category}" in my routeMap template, and then "asp-route-page" will look for "{page}" in the routeMap template?
The MS documentation is kind of confusing or just abstract, can anyone confirm or explain this better?

When using normal routing , the way you do it, the parameters controller
and are required action
and are mapped to your controller and action name.
So, if you want to navigate to Action List
in Controller Product
using Category and Page parameter, your routing should look like this:
routes.MapRoute(
name: null,
template: "{controller}/{action}/{category}/Page{page:int}",
defaults: new { controller = "Product", action = "List" }
);
Update:
The attribute asp-route
on Tag Helpers that you are using will provide parameters for routing values.
Basically, it asp-route-MyParameter
will add MyParameter
for routing values with the specified value.
