I work in an ASP.net/ SQL Server development environment. If my only concern is speed should I go with parametrized queries or should I use an ORM such as nHibernate or LINQ?
View 5 RepliesSometimes my gridview can take a second or two to get into in edit mode, and other time it can be 5-10 seconds. Is there something I can do to make the transitions from each state more uniform?
View 3 RepliesI'm now reading this article:[URL]But I don't understnad why this is better than just writing code, methods that connects to DB and get from stored procedore what I need.
Why is it better to use so much DataSets for all the tables and more.
I have a gridview that displays query results on a reporting page for a "home-grown" CRM application. From the gridview, a link can be clicked which opens a modal window that contains an iframe linked to a "details" page where record specific info can be viewed/altered. On the details page there are 10 or so dropdownlists (ddls) that are bound every time the page is called. The ddls are bound using a method similar to the example below. I am looking for a way top speed things up a bit. The details page could be called 10-20 times in one session and every time the page loads these ddls have to be bound from the same methods but for different records. What are some options for speeding up the load time for this page??

I am facing problem with images loading time. In my form I have image server control placed in repeater control. The repeater control every time binds atleast 300 images. When we want to see all the images at a time the page is taking lot of time(atleast 3 to 4 mins) to display. But I need the page should be loaded fast.
The image url is from physical location.And the information related to image is coming from database.
I am using .net framework 3.5 and C#.net as language in asp.net web application.
I am having some difficulties with a particular task. I am creating a support desk intranet application and I am trying to write a method within a class within a namespace which will form a generic database connection which can be called from any of the aspx pages so that I have the dbconnection logic in one place; you know, going along with the 'DRY' (Don't Repeat Yourself) mantra.
The Namespace:
SUPPORTDESK.SQL.dbconnection.pullData()
Objective of the method:
To provide any aspx code behind file with an SQL Server 2005 Express Connection and if possible return the data from an SQL Query. This is where I need advice do I create the method such that it simply forms the connection and returns a DataSet or that it returns an SQLConnection object? If i've got things back to front and upside down don't worry I'm a beginner with ASP.NET. The Method so far:

If I'm on the right track how do I access the data returned in the DataSet?
I can use similar code below to select a row in my database when I enter a value (username) in text box and it successfully retrieves.however, I'd also like to delete row from database based on the username i enter in text box. My code runs but no row is deleted...my code is:

I 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?
I keep all of my code in codeLib.cs and use it on various ASP.NET pages. However, I still have to do the databind(); in the code behind page for each aspx file. How can I eliminate all code in the aspx file so I just have the UI in the aspxand the code and databind(); in codeLib.cs.

View 1 RepliesI am using an SQL Express server hosted on a different machine and it is listed in my server explorer just fine. It is listed as my connection string in my web.config just fine as well and lastly it seems to sync just fine with my asp.net membership tables. My question is does it need to be listed in my app data folder of my site? Currently I have the ASPNETDB.mdf connection listed, which is apparently just a local sql express connection. The database I am using in my webconfig and other files is not listed so do I need to add it there?
Second question is about DAL, Data Access Layers. I have mostly been using presentation level SQL commands with my data presentation controls. Manually entering separate select, insert and update statements. I just went through a tutorial that stated the best way to interact with your database in asp.net is with DAL using table adapters. It mentioned that it gives you the ability to use strongly-typed references to each row. My question is can I use the same method multiple times on a single page. For instance a method inside an adapter named GetProductsByID(@ID) ? What if I want this bound to three different gridviews on a single page? Anyone have any other general things to point out about using DAL over presentation level commands?
Are there scenarios where it makes sense to encapsulate a data access layer (of a ASP.NET webapplication) with WCF or WCF Data Services ? Makes it sense to use a service inside the application ?
View 2 RepliesI have a situation where I am accessing a database multiple times and I'm wondering if it is necessary.
I have a GridView with a template column with a hyperlink to "Get Results" and on the RowDataBound event I have it check the batch number against the database and see if results exist and then if they don't, hide the link.
So when viewing the page if there is 20 rows in the gridview it is effectively doing 20 queries.
I was wondering if it is a better idea to query the database once with all "batches" and load it into a datatable, then on the RowDataBound event query the datatable. The only issue I see with this is there is currently 40,000 batches and grows daily.

I have a problem and I could not solve it. Hope you can write a sample code for me. I have a Microsoft Access database, and in asp.net website, i draw a grid view on the design page. I also configure the source data access. It works, but display all the data in the database. i want to display all the data which is related to John. sql = "select username, customer_name, phone from db where username = John" how do i configure the data grid view?

I would like to write an MVC application that accesses multiple data stores (SQL Server, MySQL, Cloud based, etc.).Most of the examples I see use LINQ to SQL for their data access but I read somewhere that LINQ only supports SQL Server - it may have been an old post.I was wondering what the best way to access these different data stores would be. Can I use the Data Access Application Block from MVC to access these data stores?

I am storing a custom "Organisation" object as a session variable. One of the properties of the Organisation object is "OrganisationID" (integer). I have a DataSource that requires a parameter value to run, and I want to use a SessionParameter to populate this. In a previous version, I stored the OrganisationID directly as a session variable. In that case, I could easily access it like this:
[Code]....
However, how do I now access the OrganisationID property of an "Organisation" type session variable (called "Organisation")? I have tried this, which does not seem to work: <asp:SessionParameter Name="OrganisationID" SessionField="Organisation.OrganisationID" Type="Int32" />

the best way of achieving the following using SQL Express 2008.I have a table with the following information in:
merchant id (an integer referencing the merchant i.e 1000)
merchant category id (an integer referencing a unique category for the merchant i.e 1015)
points (a long int)
I want to access the point data for both the merchant and merchant category.
?
i.e. merchant 1000 total points 100
merchant category 1015 total points 70
merchant category 1016 total point 30
I created a view with rollup which gives me the 2 levels i need, but i'm unsure as to whether this is the most efficient way of achieving my goal.Ideally I'd like a view to show the following:
merchant category 1015 category points 70 merchant points 30 rather than:
merchant category 1015 merchant 1000 points 70
merchant category 0 merchant 1000 points 100
