In my BarFilter action filter OnActionExecuting method I want to add a value for paramA which is not set by the view so that Bar will be fully populated in my Foo action method. I've tried various methods of adding values to ViewData, ModelState, Model etc. but I always get a null returned in Foo.

Here is the json that I'm building on the client and sending to the method:

I have been able to pass in simple data types and a single instance of the Code class, but I can't seem to find the magin to pass a List to the server method. Can anyone show me what I'm doing wrong?

I need to set a couple of Session vars by calling a PageMethod using jQuery.
The client side js looks like this:
function setSession(Amount, Item_nr) {
//alert(Amount + " " + Item_nr);
var args = {
amount: Amount, item_nr: Item_nr
}
//alert(JSON.stringify(passingArguments));
$.ajax({
type: "POST",
url: "buycredit.aspx/SetSession",
data: JSON.stringify(args),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function () {
alert('Success.');
},
error: function () {
alert("Fail");
}
});
}
and the server side like this:
[System.Web.Services.WebMethod(EnableSession = true)]
public static void SetSession(int amount, int item_nr)
{
HttpContext.Current.Session["amount"] = amount;
HttpContext.Current.Session["item_nr"] = item_nr;
}
only, it seems that the Session vars are not set. When I try to Response.Write out the Session vars, I get nothing. I get no errors, and I can alert out the values passed from the onclick event, to the js function, so they are there.

When I submit form get an error of mapping but if I take FullName out of complex type than form is working fine.How I validate FullName if it is in Complex type?
I want to display an editor for a type User. User contains a field Address of type Address. I made an editor template for the type Address so that it is reusable.
I don't want the field Address to be required for creating a user. But some fields are required for Address, for example country, state etc.
I want to validate Address if I receive any data for it, if I don't receive anything, then I don't want to return any validation error to the UI for Address. I would return only validation errors for User then.
can someone give me a high level overview of what the differences are? why would you choose to use one over the other?
View 1 RepliesI have this complex type property and I couldn't seem to get those properties in my List.Class Overview:
FullName
Address (complex type)
Street

i have a movie object and the movie have comments collection inside it
public class Movie
{
public List<Comment> Comments{ get; set; }
}
so i have a strongly type view like this :
public ActionResult Details(int id)
If I have Database Stored Procedure retrun Complex type (Contain from Columns for 2 tables) ( Composite) and No Relation between them so i can't use Navigation Property ... so how can I use That in ADO.NET Framework specially when i try to use Add Function Import i didn't find any thing else None, Scalars, Entites.
View 1 RepliesI seem to be having issues with posting forms with DropDownLists. I've looked all over the net and tried various solutions, but none seem to work for me.
I'm getting the following error: The parameter conversion from type 'System.String' to type 'Models.Organization' failed because no type converter can convert between these types.
Here's my ViewModel:
[Code]....
Here's my controller:
[Code]....
The objects are generated by ADO.NET Entity Framework. Organizations is its own object, but also a property of Profile (each user belongs to one organization). Now I understand what the error message is saying, just not sure how else I'm supposed to do this.
I have 2 classes that are used to mirror the data from an ajax call. One (Customer) contains a property which is name, and the other is an array of Products.
Public Class Customer
Private _Name as String
Private _Products as Product()
Public Property Name() As String

So part of my web app centers around this very important form which is used to create a form. Its like google docs form. The user keys in a type (checkbox, textfield, numericfield) and a label and slaps it into the system, and it generates a form somewhere.
Its a little more complex than google forms, the field types are complex and theres a lot more to that form (It happens to be a form generator for a finance plan)
The app is asp.net, I was thinking of using jquery and jquery's own ajax methods to post the data, but I think it would just turn into a very hairy situation, I then thought silverlight, but Ive never done silverlight before but I am an experienced .net guy.
So what do you guys think, will silverlight be too tough for a first timer for this kinda thing? Or should I stick to jquery. Plus points for silverlight is its an inhouse lan app and this particular page will be used by people with very high bandwidth.
Also I'm on .net 4 btw.
I am posting a Jquery Json serialized object to my controller but not all of the data is getting passed. One of the members is a complex type that is also Json serialized. This is the one that isn't getting through to the controller.
Here is the class I'm passing to my controller via Ajax post. Note the complex type, RoutingRuleModel.
SourceCodeModel.cs:
[code]....
Problem: SourceCodeModel contains correct values EXCEPT for it's complex member: RuleModel, which comes back as a RoutingRuleModel with default (null or 0's) values.
This in in an ASP.NET application.
Locally, this code runs fine, but on our production server, it throws an exception of 'Parameter is not valid' when Bitmap.Save() is called.
Should I not be using System.Drawing.Bitmap because its not recommened based on this:
[URL]
Classes within the System.Drawing namespace are not supported for use within a Windows or ASP.NET service. Attempting to use these classes from within one of these application types may produce unexpected problems, such as diminished service performance and run-time exceptions.
What else could I use?
Bitmap myBitmap = new Bitmap(img);
myBitmap.SetResolution(img.HorizontalResolution, img.VerticalResolution);
// get the tiff codec info
ImageCodecInfo myImageCodecInfo = GetEncoderInfo("image/tiff");
// Create an Encoder object based on the GUID for the Compression parameter category
System.Drawing.Imaging.Encoder myEncoder = System.Drawing.Imaging.Encoder.Compression;
// create encode parameters
EncoderParameters myEncoderParameters = new EncoderParameters(1);
EncoderParameter myEncoderParameter = new EncoderParameter(myEncoder, (long)EncoderValue.CompressionCCITT4);
myEncoderParameters.Param[0] = myEncoderParameter;
// save as a tiff
myBitmap.Save(input, myImageCodecInfo, myEncoderParameters);
If I use jQuery AJAX to call a specific ASP.NET page method how to have that method return a value back to the AJAX method that called it?
Update
My situation is I have an existing web application with many existing methods. I would like to be able to use jQuery to execute some of these methods and then update the UI with the results. My mandate is to stay away from ASP.NET AJAX and stick with jQuery. Management is concerned about continued development and support with ASP.NET AJAX from Microsoft. I agree with them.
I'm designing a page which makes an ajax call (via jQuery.ajax) to a page method on the server side.On the server side, I have two classes: Agent and Channel.
In the page method, I'd like to return a List<Agent> and a List<Channel> to the client side. How can I return two lists to client side? should wrap them up in one class like:

I have the following function signuture:
public JsonResult PopulateGrid(int page, Guid? accountId, Guid? systemUserId, Guid? branchId, DateTime? fromDate, DateTime? toDate, HomeVisitType? homeVisitType)
Every single parameter is bound just fine except toDate which turns out to be always null. When inspecting the Request.QueryString["toDate"] it retrives the right value which is 30/09/2010. It seems that DateTime expects another format when binding.
What is the right format?
