How can I use Html.Action?

问题:

I am trying to understand how to use:

@Html.Action("GetOptions", )

What I would like to do is to pass a call to my controller and pass the parameters:

pk = "00" and rk = "00"

Can someone explain how I can do that with the Html.Action

回答1:

You should look at the documentation for the Action method; it's explained well. For your case, this should work:

@Html.Action("GetOptions", new { pk="00", rk="00" });

The controllerName parameter will default to the controller from which Html.Action is being invoked. So if you're trying to invoke an action from another controller, you'll have to specify the controller name like so:

@Html.Action("GetOptions", "ControllerName", new { pk="00", rk="00" });

first, create a class to hold your parameters:

public class PkRk {
    public int pk { get; set; }
    public int rk { get; set; }
}

then, use the Html.Action passing the parameters:

Html.Action("PkRkAction", new { pkrk = new PkRk { pk=400, rk=500} })

and use in Controller:

public ActionResult PkRkAction(PkRk pkrk) {
    return PartialView(pkrk);
}

Another case is http redirection. If your page redirects http requests to https, then may be your partial view tries to redirect by itself.

It causes same problem again. For this problem, you can reorganize your .net error pages or iis error pages configuration.

Just make sure you are redirecting requests to right error or not found page and make sure this error page contains non problematic partial. If your page supports only https, do not forward requests to error page without using https, if error page contains partial, this partials tries to redirect seperately from requested url, it causes problem.
