Passing the value of a Textboxfor into ActionLink - asp.net

Having a little trouble and wondered if anyone could help :-)
I am trying to pass the value that a user enters into a html.Textboxfor to an html.Action link.
As shown below :
<%=Html.TextBoxFor(m => m.OrderQty)%>
<p class="button" >
<%: Html.ActionLink("Add to cart",
"AddToCart",
"ShoppingCart",
new { id = Model.Product.ProductId, Qty = Model.OrderQty }, "")%>
</p>
But when i put a breakpoint in the AddToCart Qty is always 0 :-(
Does anyone have any ideas ?
Thanks
John

I would recommend you using a form instead of an action link. This way the value entered in the textbox will be automatically sent to the server and you don't have to worry about javascript:
<% using (Html.BeginForm("AddToCart", "ShoppingCart",
new { id = Model.Product.ProductId, Qty = Model.OrderQty },
FormMethod.Get)) { %>
<%= Html.TextBoxFor(m => m.OrderQty) %>
<input type="submit" value="Add to cart" />
<% } %>

Rails 4 button_to using helper improper redirection

I am building an index for one of my models. Instead of the usual table, I want to have two combo-boxes: one for selecting the object, the other for selecting the method (either edit or destroy). Upon clicking the submit button, I should be redirected to the appropriate method reference (e.g. admin_users/1/edit or admin_users/17/destroy). I have written a helper that constructs the url reference, but for some reason it does not work. when I use button_to I get redirected to the create method, when I use button_tag nothing works. Any ideas?
view code:
<%= form_tag do %>
<p id="notice"><%= flash[:notice] %></p>
<h1>Listing admin_users</h1>
<p><strong>select admin user</strong></p>
<%= select_tag(#req_id, options_from_collection_for_select(#admin_users, :id, :login)) %>
<br/>
<p><strong>select action</strong></p>
<%= select_tag(#oper, options_for_select([['edit'],['destroy']])) %>
<br/>
<%=button_tag 'go go!', get_path(#req_id,#oper) %>
<% end %>
helper code:
module AdminUsersHelper
def get_path(req_id,oper)
a=[req_id, oper].join("/")
["admin_users", a].join("/")
end
end
The default method for a form submit is POST. You'll need to change the method accordingly.
<%= form_tag( '/users/confirm', method: :get ) %>
May I suggest submitting with Javascript? You'll have a more dynamic control over the method of the submission. Take a look Here
so, eventually I went on the javascript solution, just as #Hassanin Ahmed suggested. Thanks for Helping!
<%= form_tag('/admin_users', id: "admin_users_menu") do %>
[...]
<font size=4>
<u>select user:</u>
</font>
<br>
<br>
<select id="admin_user_id" name="admin_user[id]">
<%= options_for_select #admin_users.collect{|user| [user.login, user.id]} %>
</select>
<br>
<br>
<font size=4> <u>select option:</u></font><br><br>
<input type="radio" checked name="select_op" value= "edit" > edit
<br>
<br>
<input type="radio" name="select_op" value= "delete" > delete
<br>
<br>
<%= submit_tag "go" %>
<br>
<br>
<% end %>
<script>
$(function (){
$("#admin_users_menu").submit(function() {return direct_me() })
})
function direct_me(){
//getting the admin_user id
var au_id=$('select').val()
//getting the desired method
var op=$('input[name=select_op]:radio:checked').val()
//making the default url
var u="admin_users/"+au_id
var f=$("form")
if(op=='edit'){
u=u+"/edit"
f.attr("method","GET")
}
else if(op=='delete'){
f.attr("method","POST")
f.append("<input type='hidden' name='_method' value='delete'>");
}
f.attr("action",u)
if(op=='delete') return confirm("Are you sure?")
}
</script>

ActionLink routeValue from a TextBox

I'm working on the following:
1- The user enters a value inside a textBox.
2- then clicks edit to go to the edit view.
This is my code:
<%= Html.TextBox("Name") %>
<%: Html.ActionLink("Edit", "Edit")%>
The problem is I can't figure out how to take the value from the textBox and pass it to the ActionLink, can you help me?
You can't unless you use javascript. A better way to achieve this would be to use a form instead of an ActionLink:
<% using (Html.BeginForm("Edit", "SomeController")) { %>
<%= Html.TextBox("Name") %>
<input type="submit" value="Edit" />
<% } %>
which will automatically send the value entered by the user in the textbox to the controller action:
[HttpPost]
public ActionResult Edit(string name)
{
...
}
And if you wanted to use an ActionLink here's how you could setup a javascript function which will send the value:
<%= Html.TextBox("Name") %>
<%= Html.ActionLink("Edit", "Edit", null, new { id = "edit" })%>
and then:
$(function() {
$('#edit').click(function() {
var name = $('#Name').val();
this.href = this.href + '?name=' + encodeURIComponent(name);
});
});

send id from view to controller

I have a view that receives a Model and displays info of that model.
I have a submit button and when it is clicked i want it to send the id to the method to process it and delete a row that has such id.
How can I do this? I want to use a button not an html link like
#Html.ActionLink("Delete", "Delete", new { id = Model.Id }) |
Thanks!
I tried input type hidden but hasn't worked =(
You can use a form to do this... I don't use razor, but an equivalent .aspx way to do this would be:
<%using (Html.BeginForm("Home", "myaction", new { Id = 1 }))
{ %>
<input type="submit" value="submit" />
<%} %>
This will post to ~/Home/myaction/1
Just call Html.BeginForm with the appropriate razor syntax.

Use textbox value on submit as a query string variable

How would I take a text box value and use it in the query string on submit? I'd like it to start as this,
/News?favorites=True
and end up something like this after the user enters in a search and clicks search.
/News?query=test&favorites=True
The controller action looks like this
public ActionResult Index(string query,bool favorites)
{
//search code
}
This question is something close to what I'd like to do, but I'd like to use the query string and maintain the existing values in the query string.
Thanks.
Two possibilities:
place the textbox inside a <form> with method="GET"
use javascript to read the value and pass it to the server (with AJAX or window.location to perform a redirect)
Example with a <form>:
<% using (Html.BeginForm("index", "news", FormMethod.Get)) { %>
<label for="query">Query:</label>
<%= Html.TextBox("query") %>
<input type="submit" value="Search" />
<% } %>
Example with javascript:
<label for="query">Query:</label>
<%= Html.TextBox("query") %>
<%= Html.ActionLink("Search", "index", "news", new { id = "search" }) %>
and then in a separate js file:
$(function() {
$('#search').click(function() {
var query = $('#query').val();
// Here you could use AJAX instead of window.location if you wish
window.location = this.href + '?query=' + encodeURIComponent(query);
return false;
});
});
Using Darin's above <form> answer but with Razor markup:
#using (Html.BeginForm("index", "news", FormMethod.Get))
{
<label for="query">Search:</label>
#Html.TextBox("query")
<input type="submit" value="Search" />
}

Cannot call other action

I'm studying ASP MVC, and developping SportsStore (Create/Edit feature). When Create a product, Create action will view a Edit view, but when press Sudmit, it call action Create (Post), althrough I will set it call Edit action:
<% using (Html.BeginForm("Edit", "Admin", FormMethod.Post, new { enctype="multipart/form-data" }))
{%>
<%--<%= Html.ValidationSummary() %>--%>
<%--<%= Html.Hidden("ProductID") %>--%>
<p>Name: <%= Html.TextBox("Name")%>
<div><%= Html.ValidationMessage("Name")%></div>
</p>
<p>Description: <%= Html.TextArea("Description", null, 4, 20, null)%>
<div><%= Html.ValidationMessage("Description")%></div>
</p>
<p>Price: <%= Html.TextBox("Price")%>
<div><%= Html.ValidationMessage("Price")%></div>
</p>
<p>Category: <%= Html.TextBox("Category")%>
<div><%= Html.ValidationMessage("Category")%></div>
</p>
<p>
Image:
<% if (Model.ImageData == null)
{ %>
None
<% }
else
{ %>
<img src= "<%= Url.Action("GetImage", "Products", new {Model.ProductID}) %>" />
<% } %>
<div>Upload new image: <input type="file" name="file" id="file" /></div>
</p>
<input type="submit" value="Save" />
<%= Html.ActionLink("Cancel and return to list", "Index")%>
<% } %>
Please help me fix it
The code you have seems reasonable if you want it to post back to the Edit action. Your question is a bit confusing, but I'm going to assume that you want to reuse the view and have it post back to Create when rendered from Create and Edit when rendered from Edit. The easiest way is to simply omit the parameters from the BeginForm call. This will cause the form action to be set to the current controller and action, which would give you what you seem to want. An alternative would be to develop templates (display/editor) for the model but have separate views for Create/Edit that simply render the template Html.EditorFor( m => m, "ProductTemplate" ). This would allow you to customize the view -- perhaps the Create view requires you to upload an image? -- yet still reuse most of the code.
