Pass multiple parameters to the controller action

To access resource I have to pass two ids, because two ids build the key.

@Html.ActionLink("Details", "Details", new { id = item.CallerId, customerId = item.CustomerId })

I get nulls in controller action with following signature: 

public async Task<IActionResult> Details(int? id, int? customerId)

I use default routing. What should I do to pass both ids?

There are multiple ways to get this done. One of the ways is to build a ViewModel to contain both Ids. Another way is to use the HttpGetAttribute to specify the route:

[HttpGet("Details/{id}/{customerId}")]
public async Task<IActionResult> Details(int? id, int? customerId)

Here, {id} will map to id and {customerId} to customerId, provided that the received values are int

You'll have to define the source for second ID, can be from header, query param, or route param. Default routing defines the route as /{controller}/{action}/{?id} as you can see, it tells MVC where to get the id from the route.

In your case, I suggest sending both IDs as query params.
