I have a table with 5 columns: ID, Session1, Session2, Session3, Session4. What I want to do is to display the number of same items from each column. Same item can't appear in more than one column.

I want to display it like this on an asp.net page.
i use mvc 1.0 since my host supports that.i have a piece of code in my view like this and i want to change it in order to be able to show records in 4 columns.
I need to find the count of records between the first and last day of the current month.I am very new to linq and having doubts in getting the count, below is the code i have written.
I have the code below which does work, but I need to add further functionality to it. The functionality I want to add to it is the text I have commented in the code below.
Dim objSQLConnection As SqlConnection Dim objSQLCommand As SqlCommand Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Dim intID As Integer = CType(Request.Form("ID"), Integer) Dim strHeading As String = CType(Request.Form("Heading"), String)....
Before the if statement, I want to find out if the database already has records with the username in the strUser variable.
I have a problem that I cannot seem to resolve. We are using an access database to store data from a Quality Assurance Tool. I need to calculate an average on a specific column in the table, however the SQL statement needs to count the number of records that contain "0.1" and divide it by the total number of records in the table. This data is then displayed in an ASP Page.
The field name is 1.
Here is the SQL:
StrSQL = "(Select Count([1]) FROM cservice Where [1]=0.1) / (Select Count([1]) FROM cservice) As questaverage "
I am facing an intresting problem now with entity framework. if i did a count of the some table with linq statement its give some count and it is not matching with my normal sql query count. my sql query returning count of all the records in that table where as linq query returns some count which is less than sql count. is this a problem with my edmx or table navigation properties..i do have some 5 to 6 child tables inside this table with foreignkey relation. will it do a join on each child table and returns only those records. I am very much confused and don't know how to slove this.
I have a gridview and in this grid i allow paging with page size 10.Now I want to find the total number of records on every page index.For example on page index 1 I have 10 records and on page index 2 I have 4 record so how do I count the number of record I just mentioned above?
// GET /Home/Results/ [AcceptVerbs(HttpVerbs.Post)] public ActionResult Result(string searchtext) { var search = (from n in _db.NewsItemSet where n.headline.Contains(searchtext) orderby n.posted descending select n); return View(search); } }
The search works and displays a record if a record containing a keyword exists, I am struggling however to implement a feature where when the search is returned it says for example:
0 news items found
N news items match your search criteria: 'string'" displayed
