Possible Duplicate: asp.net mvc: why is Html.CheckBox generating an additional hidden input
I'm rendering a checkbox in an asp.net mvc app, and the control is also outputting a hidden field like this:
<input id="blah-64" name="blah-64" value="true" type="checkbox">
<input name="blah-64" value="false" type="hidden">
Problem is, when I post the form, the form key "blah-64 returns "on, off".
Why is this?
I want to integrate paypal inside my shopping cart. For that it requires a html form to be embeded inside .aspx page with the action to paypal and method is post. Inside that form there are some hidden input filed. I want to assign one of those hidden field's value from server side code so i need to access that filed from server side. But how? Here is my form:

how to add checkbox(input html control) which will be appear dynamically in datatable.
View 1 RepliesIn my ASP.NET MVC app I am rendering out a checkbox using the following code:
<%= Html.CheckBoxFor(i=>i.ReceiveRSVPNotifications) %>
Now I see that this renders both the checkbox input tag and a hidden input tag. The problem that I am having is when I try retrieve the value from the checkbox using the FormCollection:
FormValues["ReceiveRSVPNotifications"]
I get the value "true,false". When looking at the rendered out HTML I can see the following:
<input id="ReceiveRSVPNotifications" name="ReceiveRSVPNotifications" value="true" type="checkbox">
<input name="ReceiveRSVPNotifications" value="false" type="hidden">
So the FormValues collection seems to join these two values since they have the same name.
Similar to the "add more experience" functionality in [URL], I want to provide a "Add another location" link which should display an additional row of a set of 4 dropdowns (country, state, city, region). I'm actually using the CascadingDropDown jQuery Plugin for ASP.NET MVC [URL] for my location dropdown functionality, but I need to give the user the ability to add multiple locations. What would be the easiest way to handle this in ASP.NET MVC and jQuery?
View 4 RepliesWe have a requirement to add an image column to the very left of the jqGrid. We have multiselect set to true, so there are checkboxes on the left. Now, we want to add some dotted lines(inside an image column) on the left of these checkboxes, as we're trying to make to look a little similar to gmail where some small dotted lines are available beside the checkboxes to enable email dragging.
View 1 RepliesIn order to use hidden input, does the hidden input must be inside a form?
Is there any strategy to perpetuate the hidden input value between requests? So far I guess it's through query string / URL?
I have an input...
<input
id="ratingField"
runat="server"
type="hidden"
/>
this hidden input is used by a star rating control. the user gives a star rating of 1 to 10 by clicking on the stars and some javascript detects which star was clicked and fills the input with the corresponding number.
I want to use a RequiredFieldValidator to ensure that the client has selected a star and if not return an error message to my validation summary.but the validator seems to be throwing an exception. How do I do this?
This is probably embarrassingly easy, but I've having problems getting this to work.
On ResidentAddress.aspx, I have 2 user controls (AppName.ascx and NavButtons.ascx). When a textbox in AppName.ascx has focus, I want to update a hidden input field on NavButtons.ascx with the value of "TRUE". In the codebehind page for NavButtons, I want to see what the value of this hidden input filed is.
This is what I have so far:
NavButtons.ascx
<input type="hidden" id="IpChangeFlag" name="ChangeFlag" runat="server" value="FALSE" />
AppName.ascx
<asp:TextBox ID="txtFirstName" runat="server" onFocus="document.getElementsByName('ChangeFlag').value='TRUE';">
NavButtons.ascx.vb
If IpChangeMade.Value.Trim.ToUpper = "TRUE" Then
MyValue = true
End If
I am unable to change the value of ipChangeFlad. It always has the value of FALSE.
I'm working with jquery.ajax() I'm getting a object and I use jTemplate to write the html. My problem is now that I need to place the id of the object in a input hidden.

this is my jTemplate html file
<div style="background-color: #ccc">

I'm using jQuery to build an IFRAME and pass some hidden input values to a Download.aspx page - jQuery code looks like this
Code:
$('<form action="'+ url +'" method="'+ (method||'post') + '" target="iframeX">'+inputs+'</form>')
.appendTo('body').submit().remove();
The inputs variable looks like this
<input type="hidden" name="filename" value="mit-license.txt" />
And the top of the Download.aspx code behind looks like this
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim ctx As HttpContext = HttpContext.Current
Dim response As HttpResponse = ctx.Response
Dim sFile As String = "mit-license.txt" ' Request.QueryString("filename").ToString
[Code] ....
I could not find the INPUT value - where does it pass in? I checked the "sender" and the ctx objects and could not find it... I hardwired the mit-license.txt filename to prove that the download works...
I have been trying to set the value of a hidden input by using Javascript and then access the value from within my C# codebehind. When I run the code that is copied below, the value that is assigned to assignedIDs is "", which I assume is the default value for a hidden input. If I manually set the value in the html tag, then assignedIDs is set to that value.
This behavior suggests to me that the value of the input is being reset (re-rendered?) between the onClientClick and onClick events firing.

I have an ASP.NET application designed for a Windows CE device that needs to take in information from a scanned barcode. The device sends the scanned data as string input with a crlf to whatever field has focus. I set up my page with a textbox that takes the input and posts back to look up the item.
Now, I'd like that box to not be visible to the user, but IE complains when I set focus to it if the field is "visibility: hidden" or "display: none". I've tried moving it off screen using absolute coordinates, but setting the focus scrolls the window to the new location.

When I used the html Helper Checkbox, it produces 2 form elements. I understand why this is, and I have no problem with it except:The un-checking of the checkbox does not seem to be in sync with the 'hidden' value.What I mean is that when I have a bunch of checkboxes being generated in a loop:
<%=Html.CheckBox("model.MarketCategories[" & i & "].Value", category.Value)%>
and the user deselects and checkbox and the category.Value is FALSE, the code being generated is:
<input checked="checked" id="model_MarketCategories_0__Value" name="model.MarketCategories[0].Value" type="checkbox" value="true" />
<input name="model.MarketCategories[0].Value" type="hidden" value="false" />
This is wrong since the Value is False the checkbox should NOT be checked.
I'm using V.S. 2008 and asp.net MVC. I have a form in this page that user selects various items from Select controls. I then construct a string varible that contains each selected element's id a hidden input control that holds this information. How can I pass this variable (and it value of course) to a Controller Action? I am using regular Html Form and the Submit button.
In the following code you see the "ResearchInterests" is the one that holds the string but I can't even reference it in my Controller action, Search. How can I correct this?

I want to create input inside gridview, the id of the input is set by me. I do want to use HiddenField control because when generating the id of the control, it will set id to gridview_ctrl.....
The input looks like this: <input id="myid01" value="myvalue" type="hidden">. Note that id is generate by me in the code behind.
I have a report page, that displays many rows, each row having its own checkbox with its value being an ID field from the database.This is for a bulk operation, that will be preformed on all the row's where the checkbox was checked.So if the user checks multiple boxes, hits a button, I need to send all the checkbox values to a controller's action that will take those Id's and process them.

But it is possible to change the values for the hidden inputs from .net codebehind code? I found this post which takes a different approach of sending these hidden fields instead as a query string to paypal. Not sure I like that though as would this not possiby explose some of those fields like the return page?

Basically what id like to do change the important parts of the button and info I'm sending to make it dynamic.I know I can do something like this in the markup, but that would mean having to fetch data mulitple times was hoping I could somehow adderss the field values directly in the codebehind. Or possibly dynaically generate and insert the entire changing input type fields from the codebehind
<input type="hidden" name="invoice" value="<%= getinvoice()%>">
Possible to add them with something like this: myform.Attirbutes.Add (???). If so how do I contruct these input types in .net?As far as return logic security, I've tested that it's solid, i just need to automate the button process so I don't have to create a buy now page and button for each product.

View 2 RepliesI need to get data from a database and I need to spit out this data in html formatk using my command line app. For this I am planning to use some sort of template-engine. I was wondering if there is anything in .NET that can do this for me?
The best option would be if I could reuse the asp.net mvc template engine (razor) in my app, this way I should not need to reinvent the wheel.
