I have a "simple" method that takes a Linq entity containing the information I want to update. The method then creates a list of counties the information is to be updated for, and tries to update the information for each county.
So user goes in fills form out selects update All counties, and the information in the form should be updated for all the counties for the member. Here is the code.

The first pass through the foreach runs perfectly, the second time through I get an error: Cannot attach an entity that already exists.
What is best way to work around this?
I have though about putting the foreach loop in my business_logic layer, and have it pass both the newRecord and OldRecord, but figured I would ask, before making the code change.
I have edited the sqlprovider file in DotnetNuke as below. But it is giving an error like in my screenshot.

foreach (Control control in ContentPlaceHolder1.Controls)
{
if(typeof(Control).Equals(Telerik.Web.UI.RadEditor))
{
label1.Visible = true; label1.Text = "dhchk";
// control.CssFiles.Add("~/styles/myStyle.css");
}
}
Error;-
'Telerik.Web.UI.RadEditor' is a 'type', which is not valid in the given context
Also, is this the correct way to add CSS class to radEditor controls ??
control.CssFiles.Add("~/styles/myStyle.css");
I actually wanna add 3-4 customized classes..how to do that?
also I was wondering if I can add some javascript or something in my Master page that will detect the ALL the radEditor controls and set their css classes ? don't know much of Javascript..how can that be made possible? how do I go about that? but first I want css classes to be set in code behind..what's wrong with the code?
[EDIT]
@Geek..I tried calling like this..is it correct?
Control c = new Control();
DoSomething(c);
now its giving this error in the method:-
The type or namespace name 'c' could not be found (are you missing a using directive or an assembly reference?)
[EDIT]
I do have this namespace added "using System.Web.UI.WebControls;" why this error ??
So, I have 3 table adapters in my dataset, and trying to configure the objectDataSource will not give me the option to select the correct table adapter.
I set up a temporary website to illustrate what I am talking about, along with pics, not much, just 4 pics.
https://sites.google.com/site/configuringobjectdatasource/
The first 2 pics are irrelevant but just in case anyone thinking I don't have it set up properly. The other table adapters are working fine, which I have gridviews being populated etc.
why it will not give me the option to select aspnet_GetRecordDatesTableAdapter?
I am developeing web application using csharp. The the code is reading the text file load on to Gridview, but when I run the the code it is giving me the error as "Index was outside the bounds of the array."Where I am going wrong. The code and records are as follows:

I'm trying to display using this query:
SELECT documentcategoryname, documentname, documentid FROM documents
INNER JOIN documentcategory
ON documents.documentcat = documentcategory.documentcategoryid
WHERE documentsiteid = @siteid
GROUP BY documentcategoryname, documentname, documentid
Which gives the following results:
documentcategoryname | documentname | documentid
About Us doccy3 3
About Us doccy4 4
Map Of Medicine doccy5 5
Is there a way using vb.net I can just display the category name once, and the documents underneath it like below:
About Us
doccy3
doccy4
Map Of MEdicine
doccy5
My code so far is:
If pagesreader.Read() Then
' output documentcategoryname
mydata &= "<h2>" & reader.Item("documentcategoryname") & "</h2>"
'display document list here using while loop?
End if

I've written this code to display a group of events when the value is 12/19/2010. This means each day I need to change the "default value" to the current date to display the events of the day. I would like to make this such that the change occurs automatically, that is, on 12/20/2010, I'd like to see just the events for 12/20/2010.

I'm trying to create a menu structure, subpages within pages, for use with my cms. I have 3 tables in sql server, I would like to query all three tables and list those pages with a certain siteid, and subpages where the subid is the pageid. how to use the GROUP BY Statement to create the menu below? Or could I use vb.net to display it for me? Something like this:
sitename
page
page
page
page
subpage
subpage
subpage
page
page
Here is my query so far:
SELECT * FROM sites
LEFT JOIN pages ON sites.siteid=pages.siteid
LEFT JOIN subpages ON pages.pageid=subpages.pageid
WHERE sites.siteID = 1ORDER BY sites.siteid, pages.pagesub ASC
These are my tables:
sites
siteID int Unchecked PK
siteName nvarchar(MAX) Checked
siteAdmin nvarchar(MAX) Checked
siteLive bit Checked
Pages
pageID int Unchecked PK
siteID int Checked FK linked to siteid in sites table
pageLink nvarchar(MAX) Checked
pageBody ntext Checked
pageSummary ntext Checked
pageTitle ntext Checked
pageOrder int Checked
pageHome bit Checked
subpages
subID int Unchecked PK
PageID int Checked FK linked to pageid in pages table
subBody ntext Checked
subSummary ntext Checked
subTitle nvarchar(MAX) Checked
subOrder nvarchar(MAX) Checked
I'm attempting to further reduce a dataset/table by various user input. Part of this process is grouping the data by a timestamp prior to a summation. I'm trying to use LINQ and cannot get the data returned that I need.

How do I translate the following query into LINQ to SQL?
[Code]....
I have some duplication that I need to clean up. I wrote a SQL query that is supposed to return duplicate customers who are located in the same city and zipcode.
I have 2 questions regarding it:
1. Is the query syntax correct to find duplicate records by same city and zipcode, data is being returned but it just returns the same customer a few times?
2. I only need to do the GROUP BY clause for Fullname and City however it gives an error when the other columns are left out. The error is Address, State and Zip not being in the aggregate function or in the group by clause.
Adding all the remaining columns to the GROUP BY clause works.
Query is as below:

i have the following objects:
Event:
- EventID (PK)
- GroupID (FK)
- StartDate
Group:
- GroupID (PK)
- GroupName
What i need to do is select the last 5 events for each group using LINQ to Objects. I tried starting with:
[Code]....
But i'm not sure how i only take the last 5 per group.
The simple way of doing this is to get the groups and then have a property on that which returns the last 5 events but if i databind this i will have to use a nested Repeater/ListView. Ideally i would like to have a row foreach event.
