Url.Action method is returning wrong url string

Question

I am trying to use the following code to generate url string:

var x = @Url.Action("AddOrEditSaleOffer", "BuildingOffers", null);

However, the returned value somehow generates the the following url:

/BuildingOffers/AddOrEditSaleOffer/7

where 7 is a number that changes based on the id of the last edited Offer.

The code is in a partial view and is called using ajax call and after making an edit to the Building Offer record. I am expecting to get NO id but the url is appending an id somehow.

UPDATE:

I found the following question helpful to understand why I was facing this problem and also suggested work arounds: Prevent ambient route values from the URL from being added to Html.Action and Html.ActionLinks automatically in ASP.NET

Also, the following section in Microsoft Docs. discusses this issue: https://learn.microsoft.com/en-us/aspnet/core/fundamentals/routing?view=aspnetcore-5.0#url-generation-reference

I get the same result as if null was present. (The id is still passed). — Adnan Mohamed

The weird thing is that it works properly the first time generated, but when I call that page using ajax call after editing a record, it passes the id of the record I just updated. — Adnan Mohamed

Why dont use just var x = " /BuildingOffers/AddOrEditSaleOffer" ??? — Serge

@Sergey using Url.Action is considered more robust. The route pattern might change and a literal string would then break, while Url.Action generates the correct url. — Marco

If you don't want to send parameters in your url, you can use the other Action method overload, which takes controller and action as input parameters.

var url = @Url.Action("AddOrEditSaleOffer", "BuildingOffers");

I tried this but produced the same output. (It still passed the id of the previous edited record ).

 string url = " /controllerName/ActionName

Thanks for your suggestion. I think this might solve the issue but I want to know why my code does not work.

As pointed in the comments above: "The route pattern might change and a literal string would then break, while Url.Action generates the correct url."

in Action function that you use the description is: Generate URL with specific route value, maybe this is for it. please if the answer is useful, please rate.
