View 7 Replies I have object graph, of Customer, Contact and Address... I want to convert it to dataset and then convert the dataset to xml. i don't think there is a straight method to convert to dataset or xml, therefore the my approach is the convert the objects to dataset using Reflection.

In my project I work with Entity Framework (LINQ to ENTITY). I only have ADO.NET Entity Data Model and a DAL (Data Access Layer). I also get the data due a WCFClientService. I have a gridview that needed to be exported in Excel.
FlexCel is a tool for generating Excel files based on a template. The only thing I see in demo's is that they work with DataSets.
Is there a way to convert the data in my gridview to a virtual DataSet?
I've written the following method to get the data:
[Code]....
private void FillDetails(string pId, out string Name, out string Address)
[code]....
I have method called Filldetails(),This method uses stored procedure to retrieve information for product name and address based on productid passed from productdetails table.I am working on globalization project.We have this product information for US country but there is no product information for germany country.So dataset is empty for germany.As result I am getting error object reference not set to an instance of the object.
I have a detailsview, template as follows:
[Code]....
Codebehind: creating dataset, getting data from sql with adaptor and filling into dataset object, then setting detailsview's datasource.
I add 2 button to above template to able to edit data at asp page, and added event handlers:buttons:
[Code]....
My question is, what to do inside the detailsview update event function to able to edit and update data. My method can be wrong too.
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.

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?
Is there an easy way to populate my C# Object with the JSON object passed via AJAX?

{"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 3 RepliesI am developing a website using Visual Studio 2010, SQL server 2008 and WCF. Already i have developed DAL (Data Access Layer), for some of pages i want to use WCF services and Silverlight, I am new for WCF and i understand that all should be done in List<> for Silverlight and WCF. But all my methods in DAL will return the records in DATA SET format, So my ultimate aim is to convert the DATA SET into List. I browsed in internet and got many explanation like serialization , IEnumarable and so.... but i have 1000 of methods in my DAL, so for the each method i do not want DATA SET to LIST convertion. So i am thinking of having one common class the responsibility of comman class will be get the dataset and return the List [Convert DATA SET to LIST ] For example(Just Psedo explanation for undertanding, Ignore the Syntax error )
Public List< > DsTOLi(dsRecord)
{
// Here we will convert DATA SET to LIST
return liRecord;
}

View 2 RepliesI'm using EF4 and have created POCO objects. The problem with POCO objects are all the entity graph are ICollection....therefore cannot be serialized.
