I'm learning ASP.NET MVC 2 I want to create a wizard-type application. I was reading you can accomplish this with the help of Html.Serialize method in ASP.NET MVC Futures assembly (To help preserve state as you step through views).
I haven't seen that this is even part of MVC 3.0 as well. how certain this feature will be included for sure in the future? I'm a little wary of relying on it being there.
I'm trying to use the new Html helper extension Serialize() from the furthure assembly..
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<List<MvcApplication2.Models.ProductViewBinding>>" %>
<!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" >

<title>Index</title>
</head>
<body>
<div>
<% using (Html.BeginForm("Index", "Products", FormMethod.Post))
{ %>
<% int codeIndex = 0;
foreach (var item in Model)
{ %>
<%: Html.TextBox("Encryption[" + codeIndex + "].Value") %>
<%: Html.Serialize("Encryption[" + codeIndex + "].ID", item.ID) %>
<% codeIndex++;
} %>
<%: Html.SubmitButton("Click meh!") %>
<% } %>
</div>
</body>
</html>
Model
[Serializable]
public class ProductViewBinding
{
public object ID { get; set; }
[NonSerialized]
public object _value;
public object Value
{
get { return this._value; }
set { this._value = value; }
}
}
Controller
[HttpPost]
public ActionResult Index([Deserialize] List<ProductViewBinding> Encryption)
{
return View("Index", Encryption);
}
It returns null when posted... but if I remove the [Deserialize] attribute it returns as it should but with the ID still encrypted.
I have a little intranet application I have been writing to manage and run reports on our company's Work Orders and Service Orders. I am running into a user issue where they will make changes to a record, and then navigate away or just X out of the page without ever saving. So I need to come up with some kind of mechanism to prevent them from leaving if they make changes unless the save or discard the changes.

View 2 RepliesI've been trying to get the strongly typed version of RedirectToAction from the MVC Futures project to work, but I've been getting no where. Below are the steps I've followed, and the errors I've encountered.
I created a new MVC2 app and changed the About action on the HomeController to redirect to the Index page.
Return RedirectToAction("Index")
However, I wanted to use the strongly typed extensions, so I downloaded the MVC Futures from CodePlex and added a reference to Microsoft.Web.Mvc to my project.
I addded the following "import" statement to the top of HomeContoller.vb
Imports Microsoft.Web.Mvc
I commented out the above RedirectToAction and added the following line:
Return RedirectToAction(Of HomeController)(Function(c) c.Index())
So far, so good. However, I noticed if I uncomment out the first (non Generic) RedirectToAction, it was now causing the following compile error:
Error 1 Overload resolution failed because no accessible 'RedirectToAction' can be called with these arguments:
Extension method 'Public Function RedirectToAction(Of TController)(action As System.Linq.Expressions.Expression(Of System.Action(Of TController))) As System.Web.Mvc.RedirectToRouteResult' defined in 'Microsoft.Web.Mvc.ControllerExtensions': Data type(s) of the type parameter(s) cannot be >inferred from these arguments. Specifying the data type(s) explicitly might correct this error.
Extension method 'Public Function RedirectToAction(action As System.Linq.Expressions.Expression(Of System.Action(Of HomeController))) As System.Web.Mvc.RedirectToRouteResult' defined in 'Microsoft.Web.Mvc.ControllerExtensions': Value of type 'String' cannot be converted to 'System.Linq.Expressions.Expression(Of System.Action(Of mvc2test1.HomeController))'.
Even though intelli-sense was showing 8 overloads (the original 6 non-generic overloads, plus the 2 new generic overloads from the Futures assembly), it seems when trying to complie the code, the compiler would only 'find' the 2 non-gneneric extension methods from the Futures assessmbly.
I thought this might be an issue that I was using conflicting versions of the MVC2 assembly, and the futures assembly, so I added MvcDiaganotics.aspx from the Futures download to my project and everytyhing looked correct:
ASP.NET MVC Assembly Information (System.Web.Mvc.dll)
Assembly version: ASP.NET MVC 2 RTM (2.0.50217.0)
Full name: System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
Code base: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Web.Mvc/2.0.0.0__31bf3856ad364e35/System.Web.Mvc.dll

Code base: file:///xxxx/bin/Microsoft.Web.Mvc.DLL
Deployment: bin-deployed
This is driving me crazy! Becuase I thought this might be some VB issue, I created a new MVC2 project using C# and tried the same as above.
I added the following "using" statement to the top of HomeController.cs
using Microsoft.Web.Mvc;
This time, in the About action method, I could only manage to call the non-generic RedirectToAction by typing the full commmand as follows:
return Microsoft.Web.Mvc.ControllerExtensions.RedirectToAction<HomeController>(this, c => c.Index());
Even though I had a "using" statement at the top of the class, if I tried to call the non-generic RedirectToAction as follows:
return RedirectToAction<HomeController>(c => c.Index());
I would get the following compile error:
Error 1 The non-generic method 'System.Web.Mvc.Controller.RedirectToAction(string)' cannot be used with type arguments
What gives? It's not like I'm trying to do anything out of the ordinary.It's a simple vanilla MVC2 project with only a reference to the Futures assembly.
I'm hoping that I've missed out something obvious, but I've been scratching my head for too long, so I figured I'd seek some assisstance.
If anyone's managed to get this simple scenario working (in VB and/or C#)

I am facing an critical problem in Enum serialization in WCF. Here is the scenario: I have an enum like this...
[Serializable] [DataContract(Namespace = "http://www.geniusdoc.portal.com/serivces/2011/v1/GdService", Name = "AppointmentMode")] public enum AppointmentMode : int { // 1: Email, 2: Phone [EnumMember(Value = "1")] None = 1, [EnumMember(Value = "2")] Email = 2, [EnumMember(Value = "3")] Phone = 3 }
Here I decorated each enum value with [EnumMember], so that I can use the Enum as Data Contract in WCF.
And, AppointmentMode will be saved as INTEGER in database. So I need to serialize this Enum to its value. So I have specified value to each member like... [EnumMember(Value = "1")]
Problems:
If I use the above code as it is...SvcUtil not considering Enum Text, and generating the Enum in Proxy as below...
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "4.0.0.0")] [System.Runtime.Serialization.DataContractAttribute(Name="AppointmentMode", Namespace="http://www.geniusdoc.portal.com/serivces/2011/v1/GdService")] public enum AppointmentMode: int { [System.Runtime.Serialization.EnumMemberAttribute(Value="1")] _1 = 1, [System.Runtime.Serialization.EnumMemberAttribute(Value="2")] _2 = 2, [System.Runtime.Serialization.EnumMemberAttribute(Value="3")] _3 = 3, }
If I remove the Value from [EnumMember(Value = "1")], while deserialization is considering Enum Text, and giving results as below
<AppointmentMode>None</AppointmentMode>
Expected result:
1. Enum in the Client proxy should be same original Enum.
2. Enum Deserialization should consider EnumValue, such a way that it will return
<AppointmentMode>1</AppointmentMode>
How to get this done?

Dim xml As String = sb.ToString

End Sub
I am attempting to serialize my linq collection of customers. But it keeps throwing
Type 'System.Data.Linq.DataQuery`1[MyDB.Customer]' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. See the Microsoft .NET Framework documentation for other supported types.
My issue is that I have already marked the dbml Serialization Mode to UniDirectional and when I check the dbml codebehind all of the DataContract()> and DataMember()> elements are there.
I am not sure how to proceed. I have tried adding various dataloadoptions and setting deferredloading to false, but no luck.
I am using Flexigrid in my project to add a button on the grid toolbar I can use code like this:
"buttons":[
{"name":"Modifica","bclass":"edit","onpress":"doCommand"},
{"name":"Elimina","bclass":"delete","onpress":"doCommand"}
],
Anyway the "onpress" attribute shall contain a reference to a js callback and so this field shall not be enclosed within quotation marks.
I am using the class JavaScriptSerializer (in the System.Web.Script.Serialization namespace) to do the serialization.
How I have to declare the variable to make JavaScriptSerializer serialize like this?
"buttons":[
{"name":"Modifica","bclass":"edit","onpress":doCommand},
{"name":"Elimina","bclass":"delete","onpress":doCommand}
],

View 3 RepliesI am trying to serialize an object that has a public member of type ArrayList. If I am reading
this correctly, an ArrayList is a serializeable member. My class looks like this:
[DataContract(Name="Family")]
public class Family
{
private int _FamilyID;
[DataMember]
[Code]....
But then I'm serializing more of the properties than I want. I would be happy to either a) figure out how to get DataContractJsonSerializer to serialize my ArrayList or b) get JavaScriptSerializer to have the effect of honoring a datacontract. I understand that JavaScriptSerializer is depricated so I suppose DataContractJsonSerializer is the way to go if possible.
