in which after changing the appropriate value if user clicks on "Save and Next" or "Save and Previous"
then by saving that particular record I have to move to the next or previous record respectively.
So in that record should be saved as well as it should display another record also in the screen.
I had done this problem with the help of normal SQL query in Asp.Net but in that case I have to solve it using LINQ.
How do I make it so when users click on an 'up' or 'down' button in a gridview that it moves the records visibly up and down in the list of records for that gridview?

I have a page (page A) displaying a GridView of records from a SQL table. Upon clicking on a row, user will be lead to another page (page B) displaying the details of the selected record. From page A, I passed the value of a generated ID through querystring to page B, and based on this ID, the application will query the database to fetch all the values and display accordingly in a FormView. Page B will also allow user to edit and update the record.
How is it possible if I want to have the ability to navigate to next/previous record from Page B without having to go back to Page A again?

I'm working to move my simple asp.net website to a three layer architecture. Currently I have Linq queries like the one below in my code-behind files. Basically this code snippet retrieves a collection of customer data from the database and then binds it to a grid control.
I'm wondering if someone can guide me on how to rewrite this in order to move it to my newly-created data access layer. I'm thinking I will turn it into a class (e.g. GetUserBoxesByStatus()) that can be reused throughout the site.
var boxes = from p in sbm.Packages
where p.UserID == CurrentUserId && p.StatusID > 1 && p.StatusID < 3
select new { p.PackageTag, p.PackageName, p.DateReceived, p.DateShipped }; [code]....
Some of the options that I've investigated but have not had success implementing are the following:
DataTable --- returning a DataTable seems like the best solution but it also appears to require a lot of potentially unecessarry code to define a table (isn't the data source already mapped in my Linq 2 Entities dbml?)
IEneuerable --- I think I could pass an IEnumerable list between the layers but after reading many tutorials about Linq I'm still a little lost DTO --- Conceptually I think I understand what a DTO is but I am not clear on how to begin implementing this approach POCO --- Again, the concept seems logical enough but I don't know how to put this into practice
how they would tackle this using one of the above or some other solution.

I am having trouble with duplicate records. I tested .distinct() in several areas and nothing helps.
I got the search criteria from the PreviousPage. I then used this criteria to search QueryA.
I did a search using QueryA. I took the results, and put the IDs into an array.
I then did a search using QueryB, that matched the IDs in the array. QueryB is used for the ListView and to page records.
Using test records. QueryA results = 2 records. The array.length = 2. QueryB results = 3. ?
What am I doing wrong ?
Some of my Code:
myResults = (from r in QueryA
select r.ID).Distinct().ToArray();
totalrecords = myResults.Length; // = 2
