I'm using EF4 and have created POCO objects. The problem with POCO objects are all the entity graph are ICollection....therefore cannot be serialized.
The problem lies is passing the entity graph to stored procedure....therefore the approach i have take is to convert the entity graph to dataset, convert the dataset to xml and then pass it the stored procedure....this is the only way i could get a clean XML in my stored procedure.
I'm trying to create a generic helper method to convert entity graph to dataset.
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.
I am trying to create a GENERIC(used for any object type) function to convert object graph to dataset. but i have hit road block...how do i type cast a generic type cast..refer to the function ObjectToDataTable code marked inRed
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:
I'm having trouble using entities: I still want to use entities on my "DAL" layer, but in "BLL" layer I want to return not a collection of entities but just a Dataset with all the table I got back from Stored Procedure. How can I do that?
The presention layer don't know anything about entities, if I can get just a dataset from "BLL", it will be very easy to work with it as it was before. Only the DAL and BLL layers will be changing.
P.S.
Does entities support stored procedure that is returning more than one table, I mean more than one entity?! If not, This is another BIG problem Microsoft didn't think about.
I must tell you the truth: I am really disappointed about using Entities. There is no logical support for Stored Procedure and too many problems when you want to have N-Tiers. It is like Microsoft have done only half of the work needed so this will be really usefull.

I used code below to convert a dataset to Excel. One column (MemberID) is varchar data type but after conversion it became number. For example, if MemberID = '012345' will convert to 12345 missing '0'.
I have an XML document that has a collection of objects. Each object has a key/value pair of label and value. I am trying to convert this into a DataSet, but when I do ds.ReadXml(xmlFile), then it creates two columns: label and value.
What I would like is to have a column for each "label" and the value to be part of the row. here is my sample of the XML:
[code]....
How would I convert this to a DataSet so that I can load it into a gridview with the columns: Name, Email, Website, Phone, Place of Birth, Misc, Comments, and Agree to Terms?
I 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; }
