I set a breakpoint on my httppost view and found that the value from a checkbox field was 'true,false" even though it was checked..how come it displays both values?
I created the create template using editorformodel(). The field using this checkbox is of bit datatype.
The action code is below;

Here is my Controller:
public ActionResult Deposit()

return View();

[HttpPost]
public ActionResult Deposit(DepositTicket dt)
{
using (var db = new MatchGamingEntities())
{
MembershipUser currentUser = Membership.GetUser();
Guid UserId = (Guid)currentUser.ProviderUserKey;
var AccountId = from a in db.Accounts
where a.UserId == UserId
select a.AccountId;
BankTransaction transaction = new BankTransaction();
transaction.Amount = dt.Amount;
transaction.AccountId = AccountId.SingleOrDefault();
transaction.Created = DateTime.Today;
transaction.TransactionType = "Credit";
Debug.Write("Amount: " + transaction.Amount + " AccountId " + transaction.AccountId);
db.BankTransactions.AddObject(transaction);
db.SaveChanges();
return View();
}
}

I am using a GridView Control to display multiple fileds with 0's and 1's.
I am using template fields where CheckBoxes are used.
Where exactly and how do I apply the Logic to get a checked CheckBox when field Value=1 and unchecked CheckBox when field Value=2 .Also some times to be able to write a YES where fieldValue=1 or NO where filedValue=0
Do I apply this logic using asp or C#? How?
When using the "add view" dialog in vwd is there a common practice for presenting any primary key fields as readonly to the user in the view?
By default it appears the user could change the key field value (as it is presented in a textbox) and overwrite data for that record for which the key was accidentally changed to.
Do we have to store the original record's key and then make the key presented as a label and then on the update subtitute the original key value back in for the record? Or is there something simpler?
I am displaying a table into a gridview for which I've a SQL query written which uses IF-ELSE condition. In one of the conditions, if the condition stands TRUE then one of the coloms should be eliminated from the table. But I constantly get an error:"A field or property with the name 'IXC_Vendor_Circuit_ID' was not found on the selected data source."

View 2 RepliesI have a dataview on a page. I am binding a list of Items, and each item has a Person object. So I get this exception "field not found in selected datasource" when I try to bind to any property on the person object.

It appears that the dataview is having problems with the person object because it will display all the properties for the Item correctly.
why I get a not found on the boundfield and not on the eval?

I created a MVC project. Added a area "SampleArea". Then added a controller "Log" in the area. Generate a view for "Index" in the log controller.
Modified the global.asax to this
routes.MapRoute(
"Default", // Route name
"{area}/{controller}/{action}/{id}", // URL with parameters
new { area = "SampleArea", controller = "Log", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
I also modified
ontext.MapRoute(
"SampleArea_default",
"SampleArea/{controller}/{action}/{id}",
new { controller="Log", action = "Index", id = UrlParameter.Optional }
);
Pressed F5 and it is giving err "The view 'Index' or its master was not found". How do i fix it?

Trying to create a strongly typed view but the model "that is a class" is not listed in the "View data class" dropdown?
View 3 RepliesI 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 know that you can use exclamation sign to bind array of simple types (like string) to GridView like this
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Array Field" DataField="!" />
</Columns>
</asp:GridView>
But this doesn't seem to be the case with DataNavigateUrlFields
<asp:HyperLinkField DataNavigateUrlFields="!" DataNavigateUrlFormatString="RoleInformation.aspx?role={0}" Text="Manage users" />
and I get following error:A field or property with the name '!' was not found on the selected data source.
I've create an asp.net MVC 2 project, it works fine!!

When I tried to add the following "Checked='<%# Eval("BOARD") %>' it does not like it and gives an error.How do accomplish the same for the above checkbox field and the exact syntax to be used
I used to be able to view the pages of my ASP.NET 3.5 website locally via the 'View in Browser' facility. However, this no longer works (for any page). All I get is a 'HTTP 404 Not Found' error message.
Where might I have screwed things up?
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

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 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:

The View:
[Code]....
The Controller:

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.
I have three asp checkbox controls and button click. If any of those three checkboxes is not selected it shoudld validate . How can i accomplish this?
I have a checkbox template field in a grid view control. I want to execute some code when a checkbox is checked or unchecked - how do I do this? Which event is fired?
View 1 RepliesAs far as I can work out I should be able to copy a web project/application to my IIS Web server and be able to see it as I do when designing it on my development computer.
The problem is once I copy the folder over to my web server and then try to view it the browser it says Error 404 not found. There must be a real simple fix for this. I would like to be able to develop ASP.NET sites using the Visual Web Developer instead of Dreamweaver but this little issue is stopping me.
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.".
