When my site runs the following code it works just fine 99% of the time.
[Code]....
The command is calling a SQL Server 2005 stored procedure that takes 20 parameters and returns 6 tables of about 5-50 rows each. The paramters are all NVARCHAR, INT, or BIT data types. Only one of the parameters is Input/Output. There is a total of about 100 rows returned. Normally this takes a fraction of a second, but for some queries, it times out after 30 seconds.
When I run the exact same query in the Management Studio query window it takes 1 second.
what I can do to get the same performance from .Net as I am getting from Management Studio?

My question is that, for each control the Stored Procedure called or not? If it is yes then it is time consuming and I need to use LINQ to DataSet or LINQ to Object rather than to call SP for each control. What is difference between LINQ to DataSet and LINQ to Object?
Should i use dataset in code behind or SqlDataSource on the form designer to fill or bind a DropDownList in my asp.net page I am currently using SqlDatasource on the form and i bind the control to MySqlDatasource because i find it is very easy and to much faster but somebody told me to use dataset from code behind because of security and performance

I'm new with programming. I have a GridView that have the specific user data. When the user log in I retrieve the data for that specific user.

If i use the multi delimited than error shows.How to use the multi delimited.If i run the code to to load the text file given in above show the bellow error
Input array is longer than the number of columns in this table.
'm not sure if this is the right forum, but I couldnt find one for linq related questions.I have the following problem. I have four tables, One with users, one with projects, one with the users and the projects they are in (joinProjectTable) and on table where the users can fill in there worked hours for a certain project. These hours are filled in on a daily base. Now every month there is going to be created a report on the workedHours table so there is visible which user has entered how many hours for a certain project. On this report there is gonna be a billing for the company where for the hours are worked. This is the easy part, the hard part is the following.
companies also want to have a list of users that didn't entered any hours for that particular month for a particular project. So I have to write a linq query that would look in the joinprojecttable to see which users are joined to which projects, and than with that join it should look if that particular combination (user+project) is in anyway entered in the workedhourstable for that particular month. If not this has to be shown in the datagrid, for every user that isnt in the workedhourstable for that month. So it should be a certain NOT query, but I can't seem to figure it out.does anyone have any idea to accomplisch this in Linq2Sql? I'm using VB instead of C#.
ite on dataset model and I used to write sql quires into dataset and call them with in my c# code as usual. and used the datatablein c#code to access the values of each column which corresponds to a sql column in the sql table. after a while I found my website going on too slowso I decided to use linq to sql classes. i can write queries in c# code

The following code works fine for converting an XML data set to be enumerable for Linq.
'Query webservice for data
Dim propertyInfo As String = myService.GetProperty(userName, password, Acct)
' Create a new DataSet.
[code]...
However, it does not retain the xml tags in the Linq enumerablerable dataset ('newDataSet2"). I don't think I can rely on the array index order as being the same everytime, so this would obviously cause a problem if I'm trying to align the array items up to my database fields. How can I make newDataSet2 retain the XML tags (column headings) to insure I know what data field each array item belongs to?
how can i delete a row in datatable using linq to dataset?
I have a dataset in my project, need to delete some rows filtered by ID
how can i do?
