I am new to LINQ. I have a GridView which I am populating using LINQ. My LINQ statement is taking query string from previous page. The query string is in string format. Here is the code:
protected void Page_Load(object sender, EventArgs e)
{
string getEntity = Request.QueryString["EntityID"];

I'm currently developing a web application using SQL Server 2005, ASP.Net MVC, ASP.Net SQL Membership Provider (for authentication and authorisation), and Linq to SQL. Everything works great and is running as planned in the development environment.However, the production environment has a SQL Server 2000 installation, and we are unable to obtain a copy of SQL Server 2000 to use in development.Upon deploying the web application to the the production environment, what options do I have for migrating the database (schema + data) from 2005 to 2000?

View 2 RepliesWe are building an extranet loan status check website using ASP.NET MVC with a WCF backend. Its a pretty standard design with the MVC site using a WCF service reference to get customer objects. The ervice uses an Oracle backend + http binding, and won't be hosted on the same server as the MVC site (so we can't use tcp binding to reduce latency).
The problem we encountered is that every call to the service is resulting in a 7-8s response time which is unacceptable for an extranet site and much higher than the 2s magic mark. The service method(s) call 12 stored procedures to create the customer object. The database is, unfortunately, denormalized (we can't change it as its also used by other inhouse production systems) so most of the calls are basic select statements which populate the customer object and its associated objects. The service proxy is properly opened and closed/disposed in the MVC actions so there are no instances of any service connection leaks. A new client proxy is created for every request (i.e., we are not using the singleton pattern for the service). how we can speed this up ?

I have some text files I need to parse in order to display my data, and what I have now are two text files with lots of redundant data. Instead of this I would like to replace the redundant data with a number referencing the text in another text file.
View 1 RepliesI am interested in learning how to develop a custom asp.net ajax gridview, and I have obtained some books on the subject, but would still like a quick answer for a question: When developing a custom ajax server control, can I somehow use jquery for the client-side part of the control? Are there any collisions with ASP.NET AJAX framework and are there special requirements (e.g. only available for .NET 4.0 etc.)?I would also appreciate any suggestions on resources from which I can learn more about developing a custom asp.net ajax server control from scratch.
View 5 RepliesMost of my experience has been developing 'webpages'. Presently, I am developing a mozilla extension which does not support web services, others have suggested to use XMLHttpReqest instead. I have the client side code for it but have no idea on how to write the server side for it.

I have table with 'usercard' name , and a related tables :
- Computer

the result show a one user in 4 rows,(user have all devices)
Suppose I have two tables "t1" and "t2"
t1 :
id FirstName Age
1 Joe 22
2 James 33
3 Bart 28
t2:
id LastName
1 Coymer
2 Manes
I can combine the data from the two tables using an inner join.
1 Joe 22 CoyLap
2 James 33 Manes
The problem though is that the person "Bart" with an Id of 3 is left out because he does not have an entry in the second table.So how can I include Bart in the output in such a way that the output might look like this:
1 Joe 22 CoyLap
2 James 33 Manes
3 Bart null null
Or spaces can instead appear for Barts last name and age instead of null.Basically I just need Bart in the output as well even though he has no age and last name.
