This seems a little clunky, as in slow. Is there a better way to get the Class B (User) information without making a query every time?

My question is that, for each control the Stored Procedure called or not? If it is yes then it is time consuming and I need to use LINQ to DataSet or LINQ to Object rather than to call SP for each control. What is difference between LINQ to DataSet and LINQ to Object?

In "query" there are several columns, 2 of them are NIIN and Qty. In "objViewDDRT" there are only 2 columns, they are NIIN and AvailBalance.

What I need to do is for each row in "query" check to see if the NIIN is in "objViewDDRT", and if it is get the AvailBalance for that NIIN from objViewDDRT.

DataSource Controls :: Pull All SQL Objects From A Database?

Jun 10, 2010

I was put in charge of a database that has no source control, and all work was done in the database. I want to pull all the objects (stored procs, views, tables) from the database, and add to my new source control.

Is there a way to get all the objects into individual files out of a database?

Our database is SQL 2005. I have Visual Studio 2005/2008/2010 (beta 2) at my disposal.

ADO.NET :: How To Use LINQ In Order To Filter Out Only Objects

Nov 24, 2010

I have a collection of objects that I want to use LINQ in order to filter out only objects that have properties that meet a certain criteria. I am not big on LINQ so I am not sure how to do this.

I create a basic LINQ statement and get the records this way

Dim lr As IEnumerable(Of LogRecord) = From rr In _logRecords where rr.username="something"

but I only want to add that where condition if someone actually filled in a textbox.

I have other conditions to do the same thing with.

ADO.NET :: Referencing LINQ Objects In HTML?

And I want to be able to for example check if my linq returns any data and if so iterate through it using a foreach loop in my HTML. change my linq so that it returns a generic list rather than what it is doing at the moment.

Serialize Linq Objects Not Working?

Apr 14, 2010

Using the following code:

Private Sub MakeMeSomeXmlBeforeRyanGetsAngry()
Dim db As New MyDBDataContext
Dim customer = From c In db.Customers Select c
Dim dcs As New DataContractSerializer(GetType(Customer))
Dim sb As StringBuilder = New StringBuilder
Dim writer As XmlWriter = XmlWriter.Create(sb)
dcs.WriteObject(writer, customer)
Dim xml As String = sb.ToString
Response.Write(xml)
End Sub

I am attempting to serialize my linq collection of customers. But it keeps throwing

Type 'System.Data.Linq.DataQuery`1[MyDB.Customer]' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. See the Microsoft .NET Framework documentation for other supported types.

My issue is that I have already marked the dbml Serialization Mode to UniDirectional and when I check the dbml codebehind all of the DataContract()> and DataMember()> elements are there.

I am not sure how to proceed. I have tried adding various dataloadoptions and setting deferredloading to false, but no luck.

DataSource Controls :: Accessing Array Objects In Sql Statement?

Jun 6, 2010

I have a gridview control that displays expenses claims received from clients. I have a template field that contains a checkbox - if this is ticked, a value from the gridview is added to a variable and this is outputted to a label control.

What I then want to do is to update the database according to which row has been ticked. I have so far the following code that adds each value to an array, which I was then hoping to access in the sql query i.e. Update table set value = value where id = (id's added to array)..

Code as follows - so far I'm just displaying the count of values in the array to make sure they are actually being added:

Does anyone know how to do this?

Forms Data Controls :: Binding A Repeater To A List Of Objects That Have Child Objects?

Nov 17, 2010

have some Objects, lets say Employee and Role defined as below and I have defined relationships in my database that gives me a list of objects say employees and thanks to my framework each employee object also has a Role object linked via the RoleIDID, UserName, Password, Email, RoleIDRoleID, RoleNameSo in code I can do something like this

Employee emp = dataService_GetEmployeeByID(1);
string RoleName = emp.Role.RoleName;

Now here is my problemI can bind any object in a repeater and it works fine for the first level in my relationship

For instance <%# Eval("UserName") %>

But I need to be able to show the details for my child objects as well (Role) so something like this (which does not work)

<%# Eval("Role.RoleName") %>
