Using Html.BeginForm with querystring

Question

My url looks like this:

customer/login?ReturnUrl=home

In the login view, I have used this pattern of code which works fine.

Answer 1

Try @using(Html.BeginForm(null, null, FormMethod.Post, new { data_id="something" }))

It should use the default logic to construct the url, just as if you used BeginForm()

(never tried that though in such case, but I believe it should work)

Answer 2

Here's The way that worked for me

Html.BeginForm("Profile", "Partner", routeValues: new {id=Partner.partner_id},method:FormMethod.Post)

It was almost like there was a problem with overloading the method, but by specifying what things are, it seems to work fine...

Answer 3

using Reflector to look at the code,

BeginForm() will pass directly the rawUrl over to the final Form. Any other overloads on BeginForm will go through a helper utility which will strip the query string.

Answer 4

Just incase you wanted to add other attributes as well. use below code

@using (Html.BeginForm("actionName", "controllerName", routeValues: new { lang = "en" }, method:FormMethod.Post, htmlAttributes: new { @class= "my-form", enctype = "multipart/form-data" }))

Answer 5

I guess this doesn't directly answer the question, but why not just use a plain old form tag?

 <form action='customer/login?ReturnUrl=@Request.QueryString["ReturnUrl"]' method="post" data-id="something">

Alternatively, you can create a custom HtmlHelperExtension that renders a form with path and querystring. In this HtmlHelperExtension you can iterate through your querystring values and populate the routeValueDictionary which you then pass to a Html.BeginForm constructor.

If you don't want something so extensible you can just use the overloaded constructor of Html.BeginForm using @Html.BeginForm("login", "customer", new {ReturnUrl = @Request.QueryString["ReturnUrl"]},FormMethod.Post, new {data-id="something"});

Answer 6

To create a RouteValueDictionary from the querystring:

RouteValueDictionary queryStringDictionary = new RouteValueDictionary(Request.QueryString.AllKeys.ToDictionary(key => key, key => (object)Request.QueryString[key]));

Then you can use it with Html.BeginForm:

Html.BeginForm(null, null, queryStringDictionary, FormMethod.Post, new Dictionary<string, object> { { "autocomplete", "off" } })
