DataSource Controls :: Created LINQ To SQL Classes And Built The Project, Then Created An Aspx Page?

Jun 3, 2010

I have been using LINQ to SQL for quite a while (about two years). Every thing was fine until now. As usual, I created LINQ to SQL classes and built the project, then created an aspx page. However, I cannot see the DataClassesDataContext in the code behind file. It is not listed in the intellisense list.

LINQ To SQL Classes & Datacontext Are Not Created

Feb 12, 2010

For no apparent reason (of course there must be one), my web project will no longer generate LINQ to SQL classes/data contexts!!!I am going about the usual routine of right clicking the project, adding new item, selected LINQ to SQL classes, then dragging over a table from Server Explorer, saving and build but no...the bloody thing won't appear!!!Does anyone know why this might be happening/what have I done wrong?

DataSource Controls :: How To Cast Concrete Type Created In LINQ Query To The Corresponding Interface Type

May 3, 2010

I have an Interface that has its concrete class defined via a factory. Because of this I found no way to use the Interface tpye directly in my LINQ quesry so I had to use the concrete class types to creat a generic list. The LINQ query works but after calling.ToList() on the LINQ query result I get a List(of MyConcreteClass), but I need a List(of IMyConcreteClass). I have tried everything I can find: .Cast, Ctype, implicit casting, etc. but I always get back one of the (2) messages (depending on if I attempt to cast)message:

"Unable to cast object of type 'System.Collections.Generic.List`1[MyConcreteClass]' to type 'System.Collections.Generic.IEnumerable`1[IMyConcreteClass]'."
"Unable to cast object of type '<CastIterator>d__aa`1[IMyConcreteClass]' to type 'System.Collections.Generic.List`1[MyConcreteClass]'."

Here is the sample code:

Populate Dynamically Created ASPX Page?

Mar 21, 2010

what I am currently doing is creating an aspx form dynamically and saving its data by using Server.Transfer("PrssPage.aspx").

On ProcessPage.aspx I am using the Previous Page property to save the data entered by the user using the dynamically created form.

Each Dynamic Form is provided an ID for example 123.aspx

Now what I want to achieve is to repopulate the dynamically created aspx page with the user input values from database, plz note here that I do not have an aspx.cs page getting dynamically generated. I am only generating aspx page.

ADO.NET :: Taking Over A Project Built By Other Developers And They Used Linq-To-Sql?

Dec 26, 2010

I'm taking over a project built by other developers and they used Linq-To-Sql, which I've used, but not with stored procedures.

Most of them work, but some don't because the stored procedure returns a dynamic select statement. So L2S doesn't understand what return type to set for the stored procedure and it return an "int" instead of a "ISingleResult<some type>".

Even if I manually change the return type to what it should be in the data context and save (I know you aren't supposed to), the stored procedures revert back to the "int" return type. Is there any way to make them always return a particular type?

Why is this and what is it for?

C# - Is A New Object That's Created In A Static Property Getter Only Created Once

Jan 11, 2010

I'm creating a static helper class for web services I'm writing. I'm tapping into the API of Telligent and therefore creating these Telligent "service" objects that allow me to do things with the platform. For example, I'm creating a MembershipSerice object in my helper class so I can do membership stuff with the same object. In my helper class I have a property with a getter that creates a new one of these objects:

private static MembershipService _MembershipService {
get return new MembershipService(path, usr, pwd);

C# - Get The Sql Created By A Linq Query?

Jan 18, 2010

I've been developing a ASP.NET page and have been using LINQ to handle talking to MS SQL server. I'm ok at basic SQL, however I'm a lot better with designing queries using LINQ. I know they are similar but I find it easer to design complex queries in LINQ. My question is this: Is there a way to design a query in LINQ and then get the SQL that it generated? I would like to embed the SQL in a stored procedure since multiple pages (outside my control) will need to do the same query.

DataSource Controls :: Extending LINQ Classes With Different Namespaces?

Apr 6, 2010

Is there anyway I can extend LINQ classes through different namespaces?Typically in my class libraries I have a namespace for each class object and their associated DAO and service classes in a folder of my project, therefore on the front-end I can only use the namespaces associated with the given page and not clutter my intellisense or load in a bunch of excess stuff.

However, I have found that upon adding my .dbml LINQtoSQL file, whatever namespace that is in, whether it's the project root namespace or a custom one, is the only namespace I can use partial class extension in.I have tried even creating a custom workspace (placing the .dbml file in a folder) and then including a using statement to that namespace and I still cannot extend the partial classes.Is there anyway I can do this? Or to have the .dbml file count as being in every namespace? I don't want to remove all namespaces but the root one either.such when I try doing the partial class from a different namespace I get the following error:

Error 1
'Id' is not a member of 'LCFVB.EntityNS.Entity'.

Difference In Display For JQuery Created Img Tag And Created Img Tag?

Jun 2, 2010

My web page has two ways of displaying a particular content. 1. When the page is loaded, the items ( images with anchor tag) are generated using ASP Repeater. 2. When user perform some Ajax action, the images are returned as JSON and I use jQuery for creating the a & img tags.In both these methods, the anchor tags with images are displayed with width 60px. There is no CSS class applied. But strangely the display is not consistent. Here is the both displays:I wonder why this difference occur. I check this with all browsers ( IE,FF& chrome) and all behave the same. Here is my jQuery code:

$('<a>').attr({ href: '/Detail.aspx?id=' +[i].pid, title:[i].nam }) .html("<img src='" +[i].url + "' title='" +[i].nam + "' alt='" +[i].nam + "' width='60px' />").appendTo("#SummaryDiv");

Any idea why this behaviour occurs? I also checked the css applied to these elements in chrome and FF.. they seems to have all the same CSS attributes.

DataSource Controls :: Cannot Work With Dynamically Created Sqldatasource

Jan 13, 2011

My users have "demanded" to have an export function to their gridviews, and since they're running from usercontrols there's no way to modify the response stream. My workaround is to create an aspx to run in a hidden iframe. To do that, and to make it modular, I'm trying to dynamically create everything from the querystring. This *seems* to work just fine until I bind my sqldatasource to the dummy gridview. I then get "Procedure or function 'xxx' expects parameter '@NumberResults', which was not supplied."
