I'm working on using the Repository methodology in my App and I have a very fundamental question.When I build my Model, I have a Data.dbml file and then I'm putting my Repositories in the same folder with it.... IE:
Data.dbml
IUserRepository.cs
UserRepository.cs
Is it better to build the folder structure like that above, or is it ok to simply put my Interface in with the UserRepository.cs?
We have many applications. All the applications are having there one access control. I am . All the application should refer this repository for access (We can say it one point contact).
View 4 RepliesI have a question regarding a situation that occurs with GridView, ObjectDataSource in ASP .NET application. The GridView is linked to the ObjectDataSource and both are included within an UpdatePanel letting the GridView to fill in an asynchronous way from a form in the same page so it gets more rows as the user enters the data:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="ObjectDataSource1">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name" ReadOnly="True"
SortExpression="Name" />
<asp:BoundField DataField="Periodicty" HeaderText="Periodicty" ReadOnly="True"
SortExpression="Periodicty" />
</Columns>
</asp:GridView>
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
SelectMethod="GetSessionNames" TypeName="Simulation"></asp:ObjectDataSource>
<asp:Label ID="Label27" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="NewWebSessionButton" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
I start the project with Visual Studio 2008, fill the form and it works correctly. Then I stop the execution: rerun again and the data I entered in the previous run is in the GridView. Is like some sort of cache saved the data from the session before. I checked that EnableCaching property is set to false for the ObjectDataSource. If I Rebuild Web Site in Visual Studio (not just Build) then it works corretly leaving the GridView empty. Is this caused just becuase of Visual Studio? Can it be turned off? And will it happen in the final IIS it will run on?
i am trying to create a data repository and i am using L2S for the ORM.
I have created a stored procedure called sp7DayAnalysisByStock which accepts a string parameter and returns a recordset of data rows. iThe result is a set of PriceList objects which is already available in the dbml.
What i now want to is create a data repository class with the signature below;
public IQueryable<PriceLists> Get7DayStockAnalysis(string stockname)
{
}
it seems what is being returned is ISingleResult..How can i return EITHER IQueryable<PriceLists> or any IList?
I have built my first MVC solution and used the repository pattern for retrieving/inserting/updating my database.
I am now in the process of refactoring and I've noticed that a lot of (in fact all) the methods within my repository are hitting the database everytime. This seems overkill and what I'd ideally like is to do is 'cache' the main data object e.g. 'GetAllAdverts' from the database and to then query against this cached object for things like 'FindAdvert(id), AddAdvert(), DeleteAdvert() etc..'
I'd also need to consider updating/deleting/adding records to this cache object and the database.
What is the best apporoach for something like this?
My knowledge of this type of things is minimal and really looking for advice/guidance/tutorial to point me in the right direction.
I am currently using the 3-tier Repository pattern in my application. Actually it's the first time for me to implement a design pattern at all! i used to put all my code in the so called now presentation layer.
i want to implement data validation, for example, password should not be more than 10 characters and have to contain special characters. Should i put this code in the data access layer? but my data access layer contains methods that take the DTO as a parameter for example
[Code]....
and the same is for other CRUD operations (DELETE and UPDATE), so implementing such validation on the DAL would make me duplicate the code in each and every method that accepts the DataObject as a paramter. Same holds for the business logic layer where i am using it as a proxy between the presentation and the data access layers.
Eventually it has to use the same Data Objects as parameters. This only leaves me with one option which is to do the validation on the Data Object part. But i think this is not the essence of the respository pattern which states that the Data object class should only be a "container" class with no behavior.
what is the difference between these two patterns?
View 1 RepliesI am new to MVC and this really probably should not be posted here but in a different forum topic. The reason I am posting here though is I am not sure if there is something about MVC that would prevent me from doing what I am looking to do.So here it goes.Maybe I am the only one out there that thinks this way but I don't care for and don't fully understand LINQ. I Like building my stored procedures passing my data to a datareader etc... and displaying what I need.
Now that being said I am wanting to learn how to make a true Data Repository and build from there but everything I find online especially here all gives me examples and instructions on how to do so using LINQ.Does anyone know of a site that will teach me how to do this without using LINQ or any form of ORM just allow me to write my stored procs how they need to be and build my classes for data access how they need to be.I may be wrong in this but it seems to me this would be the more light weight way of doing it.Anyhow as stated above the additional question to this would be is there any reason this would not work for MVC and actually any reason it is extremely (or at least for me) hard to find any documentation on this anywhere online?
Just wondering, in an ASP.NET MVC3 environnement with entity framework. Should the Unit of Work point to the service layer or the repository (and then the repository point to the service layer) ?
Ive saw two example:
* One where the unit of work and repository both have an instance to the service layer..
Link: Entity Framework 4 CTP 4 / CTP 5 Generic Repository Pattern and Unit Testable
Doesn't use a service layer but its obvious that one could be use in that case.
* Second where the unit of work have an instance to the repository which have an instance to the service layer..

I want to fetch data from two table buut i m realy confused.
just i want recent two users in my site but problem is there that two users releted information stored in other table .
I also used join query to fetch that data but proper result not get .
I am having trouble with queries because they are not returning the data needed, and I am having trouble figuring out why because I only am testing with 2 records.First I want a query to return all records for one customer as follows:
[Code]....
There are two records with the customerID of 1, but it only returns one,next I try to return only one record, the AccountPrimary or customer_contacts.IsPrimary, but when I add " AND customer_contacts.IsPrimary = 'True' "at the end of my query it then returns both records, but only one IsPrimary = True and the Other = False. Is it backwards? I also tried another method and it returned 30 of the same record and I only have 2
I want to build a survey system where you can build a form with questions and some answers to these questions and then members who will log in will be able to take the test.
Then i want to present the different results from the test in some diagram or something like that.
I have a FormView with the ItemTemplate and InsertItemTemplate populated. In the InsertItem template, What I am trying to do is that when a user click on the DropDownList and selects the item from the list that they want, it Populates to a TextBox.
I have tried the SelectedIndexChanged event however It does not seem to fire the event.
My questions are;
What would be the proper format for a DropDownList Sender? e.g. I have tried this;
DropDownList ddlProjectYear = (DropDownList)sender;
What is the correct syntax for the FindControl? e.g. and I have tried this;
[Code]....
[Code]....
What would be the correct event that I should be using to have the SelectedValue of the DropDownList show up in the TextBox.Text?
In the edit template of the listview I have a multiline textbox. But when the row is edited and the template switches to the ItemTemplate, the text is not displaying properly in the associated Label control (missing linebreaks).
I know that the Label control doesn't understand the enter key code, and I need to do a replace on the string. What I have right now is :

I have a Formview where students put their information in such as name, address, etc. The text boxes are bound to my database, so once they are done, they choose to update, and my database is updated with their information. My problem is that the students often use All Caps to enter in their information.
I think I need the StrConv somehow, but I just can't seem to get this done. I've seen where it could be done with text boxes, but not when they were in a Formview using parameters.
I have created an out-of-the-box (default everything) ASP.NET Dynamic Data Entities Web Site using VS2010, C# and the .NET Framework 4. Created an ADO.NET Entity Data Model based off a MS SQL 2008 R2 database and registered that EF data model for my dynamic data. Everything works great except for the one change I would like to make. By default, the GridViewPager.ascx file provides the values 5, 10, 15 and 20 in the dropdown for GridView's "Results per page" option. I would like to change that to 10, 20, 30 and 40 - with 40 being the default selected option.
I went to the code behind file and modified it to have the values I am wanting. Those values now show in the dropdown, and work if I select them. Problem: when the page is first rendered only 10 rows will show. How can I change this?
It may be obvious to everyone. I am learning this: what is difference between build solution and build website
View 2 RepliesI have a large solution which has multiple apps which all share some common site elements (masterpages, navigation, etc).
Currently, all of these get built into a single DLL
If my structure looks like:
WebRoot
- Common/
- Shared/
- Images/
- App1/
- App2/
- etc
Is there a build tool which will allow me to build WebRoot.dll, App1.dll, App2.dll? I don't believe this is possible in VS2008 or the MSBuild tool.
I have a TFS build set up to deploy an ASP.net project to a test server.The build works great, and deploys to the test server fine, but instead of putting it into the Website directory that my IIS webserver is configured for, it puts the build into Website_20100511.6
Why is the date suffixed to the directory name? Is there a way to turn that off so I can publish directly to the Website?
I need to build web application that will do:1 - build web pages. 1a - build template for page. 2 - add module(by module I mean ContacUs form, Search, Billing System...).

We are moving from ASP.NET Web Forms to MVC 2.0. In most of our projects we have a typical setup to communicate with a database.
Common (objects/entities like 'SiteMenu' and 'Users')
Business Logic Layer (with calls to de Data Access Layer)
Data Access Layer
The DAL has a DatabaseHelper with common database operation, an OdbcHelper with database specific operations (eg MySQL) and a StoredProcedure class with all the stored procedures.
How is this design translated into a repository design? We want to use our own database helpers instead of NHibernate etc.
I have 2 repository that I'm trying to use in the same controller and cant find out how
This is what I'm tried :
[Code]....
for the first one it was working(VortRepository but I cant add the second )
i'm new to asp.net MVC, and I'm trying to understand the service/repository pattern and how to best implement it.
I've followed the MVC Music store tutorial, and it suggests that the public partial class ShoppingCart implements an AddToCart method looking like this:
[Code]....
Now if I would like to use the service/repository pattern in a correct way, should I just replace the row "storeDB.AddToCarts(cartItem)" with something like cartService.AddToCarts(cartItem) and then just save the added row by calling cartService.Save() instead of shopDB.Save()? The methods AddToCart(...) and Save() in cartService then calls the repository that does the actual saving.
I'm used to working directly with SQL and do NOT want to use Linq.
Pretty much I always create a class like the one below and have all the functions/methods necessary to perform a task.
How would I set up a repository without using LINQ??

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using System.Data.Sql;
