My question will probably sounds dumb to most of you but I have been struggling to find out the problem. I basically have a method and a view (created by right click-> Add View).
This is my method:
public ActionResult yearlyOverview(FormCollection values)
{
return View();
}
And this is my view:
<%# Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
yearlyOverview
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>yearlyOverview</h2>
</asp:Content>
The error message that I get comes from the browser:
Sys.ArgumentException: Sys.ArgumentException: Cannot deserialize. The data does not correspond to valid JSON. Parameter name: data
This is the master page code:
<%# Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %>

Has anybody already stumbled on this problem?
Ok my code was good but the mistake i made was to call the form using ajax.beginForm instead of a normal form, and I was trying to parse an object data that wasn't returned by the controller.

I am creating a Web Forms project with a Master Page. However, when I put a label on the master page (or any other control or html element) it does not display it on the web form. How can I fix this problem?
MasterPage:
<%# Master Language="C#" AutoEventWireup="true" CodeBehind="MasterPage.master.cs" Inherits="RWA.MasterPage" %>
<!DOCTYPE html>
<html>
<head runat="server">
<title></title>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form" runat="server">
<div>
<asp:ContentPlaceHolder ID="MasterPagePlaceHolder" runat="server">
<asp:Label ID="NameLabel" runat="server" Text="Label"></asp:Label>
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
Web Form:
<%# Page Title="" Language="C#" MasterPageFile="~/MasterPage.Master"
AutoEventWireup="true" CodeBehind="Login.aspx.cs" Inherits="RWA.Login" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MasterPagePlaceHolder"
runat="server">
</asp:Content>
Fixed it, only needed to remove the control from the content placeholder
I am trying to add a view inside a Web form and its fine to show data. But I do a post it break. I have used LINK sample which I found on sof but it wont work for POST Request. Always throwing a MAC fail error.
Webforms typically uses a single form for the entire page. But HTML does not support nested forms, so if you put another form onto the page via MVC partial view, you need to ensure the partial view is not rendered inside of your <form runat="server"> tag.
Here is an example of using multiple forms with Webforms.
<%# Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<fieldset>
<legend>ASP.NET web form (POST)</legend>
<asp:Label runat="server" AssociatedControlID="txtSearch">Name: </asp:Label><asp:TextBox runat="server" ID="txtSearch" /><asp:Button runat="server" ID="btnSend" Text="Search" OnClick="btnSend_Click" />
</fieldset>
</form>
<form method="get" action="Search.aspx">
<fieldset>
<legend>Regular HTML form using GET</legend>
<label for="name-text">Name: </label><input type="text" id="name-text" name="q" /><input type="submit" value="Search" />
</fieldset>
</form>
<form method="post" action="Search.aspx">
<fieldset>
<legend>Regular HTML form using POST</legend>
<label for="name-text2">Name: </label><input type="text" id="name-text2" name="q" /><input type="submit" value="Search" />
</fieldset>
</form>
</body>
</html>
NOTE: If your main webforms form is declared in a master page, you will need to render your MVC form inside of a separate ContentPlaceHolder control so the forms are not nested.
<!DOCTYPE HTML>
<html id="Html1" runat="server" xmlns="http://www.w3.org/1999/xhtml" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.w3.org/1999/xhtml http://www.w3.org/MarkUp/SCHEMA/xhtml-rdfa-1.xsd" xmlns:og="http://opengraphprotocol.org/schema/" >

I have a ASP.NET Application with a master site and content sites. in one of this content sites I have a Div with Controls and I want to try it make draggable with jQuery but I don't know how I can to this in ASP.NET because of the Control Id in asp.
here is my code:
master site:
...
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<link href="Styles/jquery-ui.css" rel="stylesheet" type="text/css" />
<script src="Script/jquery-1.8.2.js" type="text/javascript"></script>
<script src="Script/jquery-ui.js" type="text/javascript"></script>
<script>
$(function () {
$("#create_box").draggable();
});
</script>
</head>
<body>
<form id="mainform" runat="server">
<div class="gastzugang">
<asp:ContentPlaceHolder ID="lw_header" runat="server">
<!--Header-->
</asp:ContentPlaceHolder>
<asp:ContentPlaceHolder ID="lw_content" runat="server">
<!--Content-->
</asp:ContentPlaceHolder>
<asp:ContentPlaceHolder ID="lw_footer" runat="server">
<!--Footer-->
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
My Content Site:
<%# Page Title="" Language="C#" MasterPageFile="~/master.Master" AutoEventWireup="true" CodeBehind="CreateUser.aspx.cs" Inherits="lw_gastzugang.CreateUser" %>
<asp:Content ID="Content2" ContentPlaceHolderID="lw_content" runat="server">

I want to this:
http://jqueryui.com/droppable/
Just use jQuery UI draggable.
Make
ClientIDMode="static" in the asp.net Tag
Or Use
<script type="text/javascript">
$('#'+'<%=lw_content.ClientID%>').draggable();
</script>
You could take a look at hammer.js which covers a 'drag' style event:
https://github.com/EightMedia/hammer.js
The drag example there is at:
http://eightmedia.github.com/hammer.js/drag/
Now I don't know too much about ASP.NET but what I would try is applying the drag behaviour to anything with a .draggable class.
Hope that helps a little!
I'm trying to access User.Identity from my master page so I can figure out which user is logged in, however I can't get it to work. If I import System.Security.Principal in my master page it makes no difference:
<%# Import Namespace="System.Security.Principal" %>
I can access it fine if I try within a Controller.
Any idea what I need to do?
What about through HttpContext.Current.User.Identity?
<%=HttpContext.Current.User.Identity.Name %> Will display the current users name
HttpContext.Current.User will get the IPrincipal object.
Here is a master page that only displays the Username in the title:
<%# Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>
<asp:ContentPlaceHolder ID="TitleContent" runat="server" />
</title>
<link href="../../Content/Style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div class="page">
<div id="header">
<div id="title">
<h1 id="maintitle">
<%=HttpContext.Current.User.Identity.Name %>
</h1>
</div>
</div>
<div id="main">
<asp:ContentPlaceHolder ID="MainContent" runat="server" />
</div>
</div>
</body>
</html>
I think Its Work
HttpContext.Current.User.Identity.Name.ToString()
or
Page.User.Identity.Name.ToString()
You can use HttpContext.Current.User.Name but you need to remember that the Master Page code is executed only after the slave page code. So you can use this variable as long as you are not performing any security logic in the master page.
You can get this from:
Context.User.Identity.Name
I have a Page that is associated with a master page. In the master page, I put the css links in the head section and I put the jquery script tag and the script that contains the function to toggle the grid, but when it is not working. Looks like it is not even calling showhide when I click on an item.
Here is a snippet of the master page:
<head runat="server">
<title></title>
<link href="MainLayout.css" rel="stylesheet" type="text/css" />
<link href="ajaxtab.css" rel="stylesheet" type="text/css" />
<link href="dialog.css" rel="stylesheet" type="text/css" />
<link href="grid.css" rel="stylesheet" type="text/css" />
<link href="pager.css" rel="stylesheet" type="text/css" />
<link href="subgrid.css" rel="stylesheet" type="text/css" />
<script src="jquery-1.3.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
//master: id of div element that contains the information about master data
//details: id of div element wrapping the details grid
function showhide(master, detail) {
//First child of master div is the image
var src = $(master).children()[0].src;
//Switch image from (+) to (-) or vice versa.
if (src.endsWith("plus.png"))
src = src.replace('plus.png', 'minus.png');
else
src = src.replace('minus.png', 'plus.png');
//Set new image
$(master).children()[0].src = src;
//Toggle expand/collapse
$(detail).slideToggle("normal");
}
</script>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
Here is the div that contains the showhide function in the onclick event in the aspx page:
<div class="searchgroup"
id='<%#String.Format("master{0}",Container.DataItemIndex)%>'
onclick='showhide(<%#String.Format("\"#master{0}\"",Container.DataItemIndex)%>
,
<%#String.Format("\"#detail{0}\"",Container.DataItemIndex) %>)'>
<asp:Image ID="imgCollapsible"
CssClass="first"
ImageUrl="plus.png"
Style="margin-right: 5px;"
runat="server" />
<span class="searchheader"><%#Eval("Business")%></span>
</div>
Here is html it generates for the master and detail div:
//master div
<div class="searchgroup"
id='master0'
onclick='showhide("#master0","#detail0")'>
<img id="ctl00_ContentPanel_gvMaster_ctl02_imgCollapsible"
class="first" src="plus.png"
style="border-width:0px;margin-right: 5px;" />
<span class="searchheader">ABC</span>
</div>
//details div
<div id='detail0' class="searchdetail">
<div>
<table class="searchgrid"
id="ctl00_ContentPanel_gvMaster_ctl02_gvDtails">
<tr>
<th>Status</th>
<tr class="searchrow">
<td>2</td>
</tr>
</table>
</div>
</div>
I could not get the JQuery working and I was running out of time, so for now I decided to use the collapsible panel externder from the ajax control toolkit. When I get time, I will investigate the JQuery Issue, Thanks for all your suggestions so far. If anyone has any more, please let me know.
Your javascript is throwing an error at src.endsWith("plus.png") because there is no built in endsWith function in js. replace that with src.substr(-8) == "plus.png" instead and it works:
<script type="text/javascript">
//master: id of div element that contains the information about master data
//details: id of div element wrapping the details grid
function showhide(master, detail) {
//First child of master div is the image
var src = $(master).children()[0].src;
//Switch image from (+) to (-) or vice versa.
if (src.substr(-8) == "plus.png")
src = src.replace('plus.png', 'minus.png');
else
src = src.replace('minus.png', 'plus.png');
//Set new image
$(master).children()[0].src = src;
//Toggle expand/collapse
$(detail).slideToggle("normal");
}
</script>

" Looks like it is not even calling showhide when I click on an item." If you simplify the function with just an alert() function, does it work.
The code looks fine to me. Maybe there is some id mismatch.
You may check if jquery's path is correct in your page (that which uses this master page).
To be sure if its calling showhide() you can use Firebug in Firefox with a breakpoint in the function.
Also, it will give you more clues to debug and guess what is going wrong.
The code seems to be ok to me, too.
just a thought, if you right click view source on the browser, do you see the jquery path correctly? my experience tells me you need to resolve javascript urls on master pages (it works fine for css, but not js files)
<script src="<%= ResolveUrl("~") %>jquery-1.3.2.min.js" type="text/javascript"></script>
