MVC: Sending an ID from a view to a controller and doing something with it

Hope your controller action method "DelRec" has parameter to accept ID like:

public ActionResult DelRec(int id)
{...}

Select all Open in new window

To get id from URL (as your current url is : localhost:99998/MyController/Edit/5017)
Store into variable [myId]

@{ ... 
var myId = Url.RequestContext.RouteData.Values["id"]; 
...}

Select all Open in new window

To pass parameter (here id) use below code (use variable [myId])

 <input type="button" value="Delete" class="btn btn-danger" 
onclick="location.href='@Url.Action("DelRec", "MyController", new {id=myId})'" />

Select all Open in new window

@Mike, it is not necessary to create form just to send your id to some other action method, If you have other work to manipulate and send, then it is fine!

Just for sending id to other action method, I guess my solution will work #a42061177 !

<input type="button" value="Delete" class="btn btn-danger" onclick="location.href='@Url.Action("DelRec", "MyController")'" />

that's what your question stated!

I want to take the ID (in this case 5017)
send it to the controller action (DelRec)

You were needed take id from edit url, and then to pass id to DelRec!

Anyways, best of luck!
