C# - Declare And Use The Name Of A Function From A Json Object?
Apr 20, 2010
I have a json object collection of geo locations that I build in the server. Each of those objects has two properties: "marker" and "onClick". Marker is for storing a Google Maps marker object and the onClick stores the name of the function to be called when that marker is clicked on the map.When I'm pushing the location objects into an array using javascript in the client side, I create the markers and assign them to each location object within the array.
My problem is that when I bind the marker with the onClick property, the function won't be found in the DOM and get an error.Is there a way to declare a property in a json object for using it on an event binding?

I'm trying to create a JSON object on client-side and pass to a server-side function. Then instantiate it on server-side using JSON string representation.
So I create jSON object on client-side
var myJsonObject = {
"arg1": var1,
"arg2": var2
}
and pass it in to
WebForm_DoCallback(controlID, myJsonObject , null, null, null, true);
When I try to retrieve this JSON object on server-size I get as a string representation of JSON [object Object]
So in following server-side function, the argument value is [object Object]
public void RaiseCallbackEvent(string jsonObj)
I was expecting a string representation of JSON object. How do I pass in a string representation?

I have the following statement, I want to turn it into a Public Shared Function :
If isEmployee Then
Dim employeeInstance As New Employee
employeeInstance = GetEmployeeInstanceByUserId(userId)
Return employeeInstance
Else
Dim studentInstance As New Student
studentInstance = GetStudentInstanceByUserId(userId)
Return studentInstance
End If
Public Shared Function GetWorkerInstance(Byval isEmployee as Boolean) As ...(not sure what to write here)...
There two possible return Type. I'm not sure what I should declare for the function return type.

I've scenario where I want to insert data into database without post back. there are around 12 to 13 fields which i need to insert. I'm passing DTO from the client side which is actually Json object. Now the problem which i'm facing is how to convert that Json object which i got in webservice to the "class" (in my case class name is User) object.
[Code]....
In the above case AddNewUser method takes the object of User class. But i'm getting casting error. So how do I convert Json object to the "User" class object?

I would like to return an function in some JSON. How can I stop my function being output as text (how can i stop it being wrapped in quotation marks?).
eg: [Code]....
In script the value of name is just a string. Is there some object I can set name to that will wrap my script and emit as script not a string?I want to do this to better control the "remote" rule of jQuery validate. I have my own dataannotationmodelvalidator for it and its doing this atm:
[Code]....
Which is working fine for the most part except I can't get the value of 'name' to be a function. It comes out as a string. Alternatively is there someway to control what JSON serializer this thing is using alternatively. We need a wrapper function so you can do something like:
name = Emit("function(){ return $(this).val(); }")
and have it come out as script not a string.

We are trying to consume WCF service which returns employee details in JSON Format.
like:
{"d":[{"_type":"Employee:#","BigThumbNailURI":null,"ID":1,"Name":"E1"},{"_type":"Employee:#","BigThumbNailURI":null,"ID":2,"Name":"E1"}]}
From VB.net code behind when I am trying to deserialize it it's stating that
"Expecting state 'Element'.. Encountered 'Text' with name '', namespace ''."
Deserialization code snippet:
Dim serializer = New DataContractJsonSerializer(GetType(List(Of Employee)))
Dim memoryStream = New MemoryStream()
Dim s = msg.Content.ReadAsString()
serializer.WriteObject(memoryStream, s)
memoryStream.Position = 0.......

I want to serialize an object to json, so I'm using [Code]....
[Code]....
This is fine, but I want to return different json datasets depending on the circumstances. Lets say I have this object (a simplified example):
[DataContract]
class foo
{
[DataMember] int productId
[DataMember] string productName
double price; //not used in json.. yet
}
Which will serialize to a json object containing the product name & Id, but what if I also need to be able to return a different json object (say, productId and price but not name)? Can this be done somehow in the same object using WCF/DataContracts and DataMembers? This will be sent in an ajax query containing a collection of objects and needs to fast, so just including every member in every type of json request whether it's needed or not isn't a good solution.

I have an object called MyObject that has several properties. MyList is a list of MyObject that I populate with a linq query and then I serialize MyList into json. I end up with something like this
List<MyObject> MyList = new List<MyObject>();
MyList = TheLinqQuery(TheParam);
var TheJson = new System.Web.Script.Serialization.JavaScriptSerializer();
string MyJson = TheJson.Serialize(MyList);
What I want to do is serialize only parts of MyObject. For instance, I might have Property1, Property2...Propertyn and I want MyJson to only include Property3, Property5 and Property8.
I thought of a way to do this by creating a new object with only the properties I want and from there create a new list for the serialization.

For my ASP.Net application I need to use a HTTP REST API that returns a JSON object.Here's how the JSON looks:
message: [

I could use the DataContractJsonSerializer Class and have custom Classes defined. However, am not sure how keys like "$" would get converted to in .Net.

My json response contains json with structure (eg. "[[[],[]]]") but no actual content.
AJAX code:
[Code]....
It definitely recognizes structure (if I change the xml nodes, it reflects in the []'s) but just isn't inserting any content. I tried prefixing the web method with "<ScriptMethod(ResponseFormat:=ResponseFormat.Json)>" but it made no difference.
