AJAX :: Return Json Format From Page's Webmethod?
Jun 7, 2010I have the following web method , no success on return a correct Json format.
[Code]....
GetAll() return list of type "Company" POCO classes.
The web method complaint type "Company" could not cast to object. However I could not just return the Company type because client side Json only accept its 2 properties -"CompanyName", "ID" and I want to keep it that way.
Of cause, I had tried create a CompanyDTO which only have those two properties, but same error - "Unable to cast object of type..."
How should I modify in my web method to make it able to return a list of partial "Company" type in Json format?
AJAX :: Use Return JSON Object From Web Service As A Declared Type?
Jan 3, 2010I just hit the following issue: I am calling a web service that returns a serialized JSON object let's say: __type, FirstName, LastName (.net object Person with properties FirstName and LastName). __type's value is Test.Person
I have created a JS object using Type.registerNameSpace/registerClass called Demo.Person and it is registered on the page using the ScriptManager. Everything is working fine; I am able to get data from the server on the call back.
Is it possible to make the returned object from the web service be an instance of the declared JavaScript Demo.Person class? The idea would be to call a method like result.getFullName() on the client side without having to copy all the properties. This is just a simple scenario for more complex objects.

View 1 RepliesWebMethod Return Values In JSON Format?
Jan 24, 2010How to return values from Webmethod to the client in JSON format? There are two static int values that i want to return.Do I need to create new object with those 2 properties and return it?The GetStatus() method is called frequently and i don't like the idea of creating a special object each time just for json formatting...
[WebMethod]
public static int GetStatus()
{
int statusProcess,statusProcessTotal;
Status.Lock.EnterReadLock();
statusProcess=Status.Process; //Static field
statusProcessTotal=Status.ProcessTotal; //Static field
Status.Lock.ExitReadLock();
return ...
}
On client side I catch the return value in :
function OnSucceeded(result, userContext, methodName)
(PageMethods.GetStatus(OnSucceeded, OnFailed);)

View 2 RepliesDo SQL Queries Towards An SQL 2005 Express Server And Format The Return Value To JSON?
Feb 19, 2010I'm completely new to both VB.NET and JSON, and I'm trying to figure out how to do SQL queries towards an SQL 2005 Express server and format the return value to JSON. I got the queries working using this (perhaps very newbie-like) code;
Imports System
Imports System.Data
Imports System.Data.SqlClient
Imports System.Web.UI
Imports System.Web.UI.WebControls
Partial Public Class SQLConnect
Inherits System.Web.UI.Page
'Defines SQL variables
Dim con As New SqlConnection
Dim cmd As New SqlCommand
Dim dr As SqlDataReader
Dim ReadData As String
Dim i As Integer

'Define SQL address, database, username and password
con.ConnectionString = "Data Source=localhostSQLEXPRESS;Initial Catalog=tempdb;User ID=tesst;Password=test"
Try
'Initialize connection
con.Open()
'Specify SQL query
cmd = New SqlCommand("SELECT * FROM Member", con)
'Execute query, dump result array into variable
dr = cmd.ExecuteReader()
messageLabel.Text = "<br />Connection established<br />"
While (dr.Read)
i = 0
For i = 0 To dr.FieldCount - 1
'Dump query results into a variable
ReadData += dr.Item(i).ToString
Next
End While
'Print query results
messageLabel2.Text = ReadData
'Close connection
con.Close()
Catch ex As Exception
messageLabel.Text = "<br />Connection failed<br />"
End Try
End Sub
End Class
I have been looking at this, and I would love to see some code examples using this class or any other good method.
AJAX :: How To Format Text In C# Into Proper JSON Format
Nov 30, 2010I'm using jquery autocomplete to call a .aspx page which returns some matching words.
The jQuery stuff relies on a JSON feed to work. Currently, in my C# I'm formatting the output as a string, which ouputs something like this:
{ query:'aa','aardvark','aardvarks']}
I was hoping that because the string is formatted in the JSON format, that would be good enough for the Javascript to process but it appears not.
how to format this text in C# into proper JSON format which JavaScript can deal with properly?
How To Get Ajax.Net PageMethod To Return JSON
Jan 12, 2010I am using an AJAX.Net to call an ASP.Net PageMethod, which returns JSON serialized JSON data
{"d":"[{"Fromaddress":"testfrom1@test.com","Toaddress":"testto1@test.com"},{"Fromaddress":"testfrom2@test.com","Toaddress":"testto2@test.com"}]"}
The Response Header states the content type as
"Content-Type application/json; charset=utf-8"
However, the data is just available as a string, and does not seem to be available as JSON data from javascript. What do I need to do to work with the returned data as JSON from javascript?

How To Make Validation Optional For A Complex Type In Mvc
Feb 23, 2011I 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.
