If I create a new EDMX model and then I import a function, then I can see my function generated in the Designer. If I perform the same process but I add a T4 template (for Self-Tracking Entities) then I loose the function definition, although TT file has code adding a region named "Function Imports". Is this a bug or am I performing something wrong?

View 2 RepliesI am confused about the constructor of ObjectContext
// Summary:
// Initializes a new instance of the System.Data.Objects.ObjectContext class
// with a given connection string and entity container name.

// Parameters:
// connectionString:
// The connection string, which also provides access to the metadata information.

// set through this method, the property becomes read-only.
protected ObjectContext(string connectionString, string defaultContainerName);
I am not understanding the parameters clearly.

View 6 RepliesI need to create a hash key on my tables for uniqueness and someone mentioned to me about md5. But I have read about checksum and binary sum; would this not serve the same purpose? To ensure no duplicates in a specific field.
How can implement this? do I need to write code in my vb application which populates the tables with stored procedures or can I do this from SQL server 2005 studio express?
I have a stored procedure returned a row of data which are written in business layer logics in ASP .net C#. If I bind the data in grid view, I can read the specific cell values from the grid. However, I don't want the grid view visible to the users.
If possible, no data display at all. I only need to save two cell values into variables. how to complete the getProfileValues() function?

View 4 RepliesI have the following query which returns all appointments for a given date, grouped by client and appointment date. For those clients that have multiple appointments on that date, I get multiple rows, one for each appointment time. I only want the earliest appointment for each client, which would result in only one row per client. If I add the MIN function to SchedTime, I'm forced to put all columns in a GROUP BY clause, which isn't what I want.Can I use a derived table and/or MIN(Schedule.SchedTime) to achieve this? Or is my thinking wrong to begin with?
"SELECT Schedule.ClientId, " +
"ClientData.FirstName, " +
"ClientData.LastName, " +

Could you teach me how to make girdview pass my object (with all it properties) to my ObjectDataSource delete method please?So far the object received by the delete method has only the datakey value, other properties are null.From this article indicates that this is default behaviour - ttp://www.manuelabadia.com/blog/PermaLink,guid,c72852ae-1fdd-4934-a715-f565ceaf21cc.aspxBut i need the other properties pass to the delete method too so i can do other thing before I actually delete the record.

im working with a proyect made in ASP.Net using Webforms. Im using Entity Framework to save data on Microsoft SQL.
My question is:
Is posible to use a Static class to keep the ObjectContext of EF live and put/get entities NOT saved inside the ObjectContext??
I wan to create an Object, then added with AddObject on the ObjectContext, But NOT to do the Savechanges. All this in one webform An then, in other webform, access to the ObjectContext and Get the Object added
I have a page like Order - Order lines. Order represents by some textboxes and ddls, Order lines represents by GridView.
I want to let users add order lines without save changes to database. For example: he adds 4 order lines, fill order info and then hits Save button. Only an that moment all information should be saved to DB.
When I use code like
using (Entities ctx = new Entities())
{
//create new OrderLine
OrderLine ol = OrderLine.CreateOrderLine(1, 1, "", 1);
//add OrderLine to OrderLines collection
ctx.CreateOrderLines.AddObject(ol);
}
newly created OrderLine does not appears in my object context, so I can't access it and bind GridView to new OrderList collection.
How can I solve this problem? Or maybe there are another ways to perform this task?
I dont understand why this is occurring, my store pro worked ok before (and i am very sure i am not passing too many arguments to the store pro) but since i have switched to using a "formview"control it has stopped. store pro and ASP.NET with sql data source are shown below. Apologies if the formatting nacks up.
View 3 RepliesI have a problem here.In my database I store member status in 1 and 0, when it come to my gridview I need change 1 and 0 to active and inactive. My company is using Linq, so I must follow. I wrote in this style, I calling a changeToWord() function to change 1 and 0 to active and inactive.

It compiles with no error, but when I execute the page, it prompt out a error message to me.

I've never used the RetrieveData() function and I don't know much about it.Having failed to work it out myself could someone show me some examples of how I call this method?Here's what I know about it:
1.It hadles the work of contacting the database and creating the DataSet.2. You must import System.Data, System.Data.SqlClient and System.Web.Configuration namespaces in teh web page.3. It can be called in any event handler in the web page code.I've tried typing this method in my page_Load() but I get the squiggly red underline which indicates that it doesn't recognise this method.
I'm building an application using MVC 3 and Entity Framework 4. I've created my Entity Data Model and generated a database from it. Now I know the validation attributes such as [Required] or [StringLength(5)] can be used on the model properties to provide validation both clientside and serverside.
I would like to know if these attributes can also be generated dynamically instead of having to add them to the model explicitly? I saw that in EF 4.1 RC you can make use of the Fluent API to further configure your model in the OnModelCreating method by using the DbModelBuilder class. As shown here I'm working with a framework however that still uses ObjectContext instead of DbContext so I would like to know if the above solution can be used in combination with ObjectContext?
As a final note, since I've been trying to figure out how to generate and use data annotations it seems using view models would increase the complexity of validation. From what I read here it seems that just passing the models directly to the view would remove the need to add annotations to the models as well as the view models. However that means that you can no longer use strongly typed views when you do joins on the models and pass those to the view directly?
I'm learning EF now and have a question regarding the ObjectContext: Should I create instance of ObjectContext for every query (function) when I access the database? Or it's better to create it once (singleton) and reuse it? Before EF I was using enterprise library data access block and created instance of dataacess for DataAccess function...
