MVC :: HttpPost Create Empty Object
Nov 22, 2010
I am using a view to create some new categories in the DB but the object the [httpost] create method receives is empty, now this does not always happens. I did double check with other catalogscontrollers and so far the implementation is the same... It only happensds when i try to create a new category the CategoryController
[Code]....
the ViewModel
[Code]....
my create view is strongly typed to ViewModel and has this relevant code create.aspx
[Code]....
and my ascx file is strongly typed to the entity model directly. when the "create" button is pressed and Exception is catched and returns the same view... I have implemented this for other catalogs and works fine except for this one...any clues... by the way i´m using entity model ...

I have a simple linq query that queries the database, where QueryString = a value.
[Code]....
My issue is, if the query does NOT return any results, as the the data does not exsist in the table, hence returns 0 rows, it throws up an error which i understand. However, i have tried a few ways to check if the object has been created in the firstplace but to no vail. I have used Isnothing and DBnull but could not get it to work.

Right click on Class name and then selected create instance ,then its Constructor, there comes a dialog box, that just gives a message and a TextBox field is present there, i filled that field with any name and clicked OK.Then error message comes that "Create Instance Failed" and its error code is "0x80004005" . What's this ? How to instantiate object of my classes ?

I've created my dataset in my App_Code folder. I tested it so it works, But then when I add in my page an ObjectDataSource, it can find any object the list is empty. I looked for online some solution but I didn't find something which worked. It works when I add the code manually, but i would like to understand how come, which part I misunderstood.

Using C#, ODP.NET and ASP.NET Web Services:
ClassA is a custom class generated from a "type" in oracle database.
ClassB is a custom class generated from a "table of type ClassA" in Oracle database.
The exposed service includes a login procedure which gets a username as input parameter and returns object B. Debugging the login procedure I can see that the data is retrieved from the database but not printed in the wsdl..
[Code]....
My ClassB definition is as follows:
[XmlInclude(typeof(ClassB))]
public class ClassB : INullable, IOracleCustomType, IXmlSerializable
...
similar definition holds for ClassA as well. the generated wsdl is :
<? xml version="1.0" encoding="utf-8" ?>
<ClassB xmlns="http://tempuri/org" />
and no data printed out. What may be the problem?

I am trying to pass a key value from one page to another, using VB.net and Visual Studio 2008 Professional. I am creating a session variable in one aspx page and trying to retrive the value in the second aspx page (Dircted to by a button with the postbackurl set) However, the session object is empty when I try to access it in the second page. If, however, i put a debug hold on the code which retrieves the variable, and examine the session object from the "locals" debug window, i see contents. When I then resume the application the code retrieves the value correctly. I am executing my code using the development server that comes with Visual Studio. Could it have something to do with that?

I want to use a grid in asp.net MVC application. I did an evaluation and found JQgrid to be optimum from performance point of view(minimum posback). What is your views about this and suggest if you have any other grid in mind which performs better and which is free of cost for commercial usage. Also now a want to post data from edited grid back to server from Jquery base JQgrid .Should i do it using httpget or httppost. If i use HTTPPOST, what should i calculate in controller and what in model As per examples available on net, people are putting calculation logic in controller(See article [URL] I need to know whether it is good practice to put business logic in controller rather than restricting it for routing to view and model.
Controller code as given in mentioned website is having following code
public ActionResult DynamicGridData
(string sidx, string sord, int page, int rows) {
var context = new HaackOverflowDataContext();
int pageIndex = Convert.ToInt32(page) - 1;
int pageSize = rows;
int totalRecords = context.Questions.Count();
int totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize);
var questions = context.Questions
.OrderBy(sidx + " " + sord)
.Skip(pageIndex * pageSize)
.Take(pageSize);
var jsonData = new {
total = totalPages,
page = page,
records = totalRecords,
rows = (
from question in questions
select new {
i = question.Id,
cell = new string[] {
question.Id.ToString(), question.Votes.ToString(), question.Title
}
}).ToArray()
};
return Json(jsonData);
}
design practice and sample to implement grid with HTTPpost feature

I am just getting started with MVC after many years of WebForms development.
I have a very simple page with two textbox fields, one called Input where a user will enter something, and one called Output where I want to return some string after they post the form, much like a postback scenario in WebForms. I have the View connected to a ViewModel for strong typing.
The ViewModel:
[Code]....
The View:
[Code]....
The Controller:
[Code]....
The problem I have is that the output text "Here is some response" never gets displayed, even though I modify the value in the HttpPost method and return the viewmodel to the view. Unless (just tried it) I set the textarea to disabled with:
[Code]....
Can someone explain this behavior? It seems as some "magic" assumes that whatever was in the input fields before the HttpPost should also be there after the post, similar to what ViewState does in WebForms.

Simple question. I have an mvc controller that has method:
[code]....
The form is a non-trivial form with a simple textbox.
Question - how on earth do I access the parameter values? I am not posting from a View, the post is coming externally. I'm assuming there is a collection of key/value pairs I have access to. I tried Request.Params.Get("simpleTextBox"); but it returns error "Sorry, an error occurred while processing your request.".

I had to upgrade a sites ecuroty from a custom system to .net membership. I created all the users like this.
ds = Wservices.SelectBulkUsers()
If Not ds Is Nothing AndAlso Not ds.Tables(0) Is Nothing AndAlso ds.Tables(0).Rows.Count > 0 Then
For Each dr In ds.Tables(0).Rows
username = dr("username")
password = dr("password")
role = dr("SecurityClearance")
email = dr("email")
Dim newUser As MembershipUser = Membership.CreateUser(username, password, email, "", "", True, status)
Select Case role
Case "1"
Roles.AddUserToRole(username, "normal user")
Case "2"
Roles.AddUserToRole(username, "administrator")
Case "3"
Roles.AddUserToRole(username, "super administrator")
End Select
If newUser Is Nothing Then
errorMsg = username & " - " & status.ToString & "<br />"
End If
Next
litResult.Text = errorMsg
End If
I thought everything was fine and then went through the labourious task of replacing all the usersids used a as a foreign key in all the tables. It was only after doing this and trying to log on I couldnt, and noticed the membership table was empty. I assumed (stupidly) as it had done the users/ roles it must have done the membership. As I have already re-assigned the old user ids I dont want to import again as the userid will chnage. So my question is: Can I create a membership for each of the users in my aspnet_users table? I have the passwords etc in varchar fields at min from old table.

I'm kind of at my wits end here as it appears not many others have had this problem so it's possible that I'm missing something very simple but what is it?
I'm using SQL Express 2008 R2, Visual Web Devel Express 2010, .NET framework 4 and tell me whatever else you need to know.
I'm not being able to use add new item feature to insert an empty SQL database into my little project. It tells me connection to a .mdf file require SQL server to be installed and running on local computer. Well I can connect to server with management studio and connect to it inside VS. Database explorer will show me a database when I manually connect using tools>connect to database then data source = Microsoft SQL Server. It then shows up in database explorer. So why isn't the add new item feature working for me? What gives?

I have just started using MVC2 in VS2010, and I noticed that on the Register page DataType.EmailAddress doesn't actually do any validation, so it does not check whether or not the Email Address entered is valid. Should I write some email validation code in the HttpPost Register method of my AccountController, or is there another way to do this?

When we double click to page It creates an empty Page_Load event codeblock automatically. Or you know can create other control's event subroutine events by clicking the relevant event in properties window.
but how can we create a Page_Init ? is there an automatic way ? or should we just write its name and parametes manually is the only way ?
