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?
this is the web method I'm using to convert my DataTable into JSON string:
[Code]....
But I'm not sure this is as good and as fast as it should be. I am sending to client side a JSON string format, but I think maybe there is a better way of doing this. I know there is JSON.NET
but I didn't see there any converting for DataTables.
Is there an easy way to populate my C# Object with the JSON object passed via AJAX?
//This is the JSON Object passed to C# WEBMETHOD from the page using JSON.stringify
{"user":{"name":"asdf","teamname":"b","email":"c","players":["1","2"]}}
//C# WebMetod That receives the JSON Object
[WebMethod]
public static void SaveTeam(Object user)
{
}
//C# Class that represents the object structure of JSON Object passed in to the WebMethod
public class User
{
public string name { get; set; }
public string teamname { get; set; }
public string email { get; set; }
public Array players { get; set; }
}

View 1 RepliesI have a datatable that I need to convert into a javascript array. This will allow me to do client-side validations on my webpage.
My datatable has 6 columns. X rows depending of the query results.
I was looking to use Me.ClientScript.RegisterArrayDeclaration but I just can't find how to build my 2-dimentional array to feed to this declaration.
On google I found some exemple for a 1-dimensional array, but nothing for 2-dimentional and I am not good enough in Jscript to figure it out myself.
{"d":{"key1":"value1",2":"value2"}}s there any way of accessing the keys and values (in javascript) in this array without knowing what the keys are?The reason my json is structured like this is that the webmethod that I'm calling via jquery is returning a dictionary. If it's impossible to work with the above, what do I need to change about the way I'm returning the data?
Public Function Foo(ByVal Input As String) As Dictionary(Of String, String)
Dim Results As New Dictionary(Of String, String)
'code that does stuff
Results.Add(key,value)
Return Results
End Function
