I have
Chart1["Series1"]
Chart1["Series2"] ....
It has multiple Series and each series has Several Data points.I want to find the count ( not sum but number of datapoints ) of Data points in all the series using LINQ.Currently i do
var count = from s in Chart1.Series
select new int[] { s.Points.Count };
And then for each thorough count and find the sum. Is there a better way to do this
I would like to customize the labels on the datapoints below so they would render as (using first datapoint on the chart as an example) :
4:10 - 4:40
yellow class
Im new for LINQ, how can i count the records in this code
[code]....
So i can say Count records and its = PValue so i can use that in a EVAL(PValue) and get the total value of the records.
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.
[code]....
I have a trivial issue that I can't resolve. Currently our app uses Linq to retrieve data and get a basic integer value of the row count. I can't form a query that gives back a count without a 'select i'. I don't need the select, just the count(*) response. How do I do this? Below is a sample:
return (from io in db._Owners
where io.Id == Id && io.userId == userId
join i in db._Instances on io.Id equals i.Id **select i**).Count()
;
im trying to count the amount of users inside a chatroom, im trying to count a specific row using LINQ to SQL.
Heres the code
DataRowView dataRow = ((DataRowView)e.Item.DataItem);
string roomId = dataRow["RoomID"].ToString();
ChatRoomDataContext db = new ChatRoomDataContext();
var query = from c in db.ChatLoggedInUsers
where c.RoomID.ToString() == roomId.ToString()
select new { };
foreach (var c in query)
{
}
Where " select new { }; " is, is left blank as i am not too sure what goes there. I tried adding c.UserName.Count() but i got an error. what i need to put into that space to count the amount of records in the UserName column?
is it possible to find row count of a table using data reader?

I tried so much working with this to get distinct Words and their count. I'm using ASP.NET 2.0. And i also googled so much.
1)Ex(String): The DOTNET is Very Cool! The Best.
2) Capture all the sequences like Space, FullStop, Question Mark, Exclamation, Apostrophe, New Line....(May be with RegEx?)
3)Split Words According to the above sequences
4)Get Distinct Words(Occurences) and their count based on the input string in 1st statement.
Desired O/P:
The - 2
DOTNET - 1
Is - 1
Very - 1
Cool - 1
Best - 1

I have added a linq to sql layer in my MVC 2 application.
This is the code I am using:
using (ProductPortalDataContext ctx = new ProductPortalDataContext())
{
var Title = from aps in ProductPortal.Models.AppSettingsView[code]...
It says to be unable to find a quey model for AppSettings view and then says "where not found".
Tried googling, nothing came up. Tried searching here(first two pages) and nothing that seemed relevant popped up.But the best of all, created a new ASP.NET applicatio, imported the model using Linq to SQL and it compiled!Ok, I tried adding a button and a label to the asp.net application just to see if it would work... guess what? It doesn't!Still the same error message and I have *NO* clue what's wrong with it!
How can I find the exact phrase or word in linq sql format?

DataSet1.HtmlModuleRow row = (from f in table where f.HtmlContent.Contains(sWebsiteSearch) select f).Single();
It worked, but when I change the search string to "h" (one letter only) it works also. How can I restrict the search to exact whole phrase or whole word only?
