DataSource Controls :: Foreach (Converting From AnonymousType)?
Apr 1, 2010
I'm using Entity to SQL to retrieve some data from the database and i'm using it to fill an DataList.The query bellow is correct and working properly. My problem is when i try to convert it to an List.I've tried with foreach(EncomendasProdutos ec in produtos)but with no sucess ("Cannot convert type 'AnonymousType#1' to 'cenatolim.EncomendasProdutos'").
Is it because i'm joining tables? I need to save the values of some fields like IVA and Final from all products of the result, but i don't know how.[Code]....

I'm close to the solution I see where I am going wrong just unsure how to approach it. I want to be able to take a tables worth of data (via DataClasses) and put it in a CSV to download.
A LINQ to SQL query is performed (basically a 'Select All' from tbl_Newsletter), takes those results and the idea is to feed those results, one by one through the foreach which, inside it, is the CSV's definition e.g. List.Add(etc) as you'll see. After which the CSVExporter method is called - which works, as I can Download it, it just wont display any results.
C#: [Code]....
To which I get: Compiler Error Message: CS1729: 'Newsletter' does not contain a constructor that takes '2' arguments
with Newsletter obj = Newsletter.GetAll(); in place of Newsletter obj = new Newsletter();
I get: Compiler Error Message: CS0029: Cannot implicitly convert type 'System.Collections.Generic.List<Newsletter>' to 'Newsletter'

ASP.NET 3.5 C# I am joining two tables using Linq. Table names are MapAssets and ExitPoint. In Database they are related with 'has a relationship'
I am writing a function in my BLL to return the joined table
public List<ExitPoints> GetExitPointDetailsByProjectID(int iProjectID)
{
ctx = new CoreDBDataContext();
var exitPointDetails = from ma in ctx.MapAssets
join ep in ctx.ExitPoints
on ma.MapAssetID equals ep.MapAssetID
where ma.ProjectID == iProjectID
select new
{
//would like to have data from both tables here
ctx.MapAssets,
ctx.ExitPoints
};
return exitPointDetails.ToList();
}
This obviuosly doesn't work. And I dont know what to return at all. All constraint I have for the return is to be able to be bound to a gridview. is this the correct way? Or else whats the correct way?

I have a feedback page with rating controls and I use a stored procedure to insert the record using C#
I get an error when I try to insert about conversion.
[Code]....
I have 20 ratings and a textbox I think the error is with the last parameter @Overall
it displays on the page as 4.9 in a label control, it is previously calculated in the Calculate_Ratings(), and it is declared as a decimal, I have also tried it declared as double. My column is declared decimal(1,1) in sqlDatabase
The Error says
System.Data.SqlClient.SqlException: Error converting data type numeric to decimal. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException
Reliability Rating What is this?
Were we there on the date and times scheduled?
Rating 5 = Perfect

I have a CSV file with a date column. My database date format is MM/dd/yyyy and the column in which I wish to place the date is called "enddate"
The CSV date column may hold all sort of (sometimes INVALID) values for the date:
31-12-2009
1-12-2009
3/4/5
12-23-2009
Now, my assumption is that the format in the CSV date column is: d-mm-yyyy
My thought now is:import the date in a tablecolumn "datetext" as flat text.
Then run a SQL query that checks the "datetext" and tries to convert it to mm/dd/yyyy, if the conversion fails, just insert null into column "enddate" else insert the datevalue.
what SQL command can do this? Is there perhaps a function?

we are using transactional replication on an sql 2008 server. we try now to add a table to the replication that only consists of 1 culomn of type date and we insert the dates to the table. when we then create the replication we are getting an error on the creation of the snapshot. here is the create table with the insert dates:
USE [Product]
GO
/****** Object: Table [TimeSlices].[BaseDate] Script Date: 05/03/2010 15:52:24 ******/
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[TimeSlices].[BaseDate]') AND type in (N'U'))
DROP TABLE [TimeSlices].[BaseDate]
GO
USE [Product]

/****** Object: Table [TimeSlices].[BaseDate] Script Date: 05/03/2010 15:52:24 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [TimeSlices].[BaseDate](
[TargetDate] [date] NOT NULL,

[TargetDate] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
INSERT INTO [TimeSlices].[BaseDate] SELECT TargetDate FROM [TimeSlices].UDF_GetTravelDateRange(GETDATE()-2 , GETDATE()+1000)
attached is the UDF:
[Code]....
this is the add article:
use [Product]
exec sp_addarticle @publication = N'Product$(QuoteNumber)', @article = N'BaseDate', @source_owner = N'TimeSlices', @source_object = N'BaseDate', @type = N'logbased', @description = null, @creation_script = null, @pre_creation_cmd = N'drop', @schema_option =

@upd_cmd = N'SCALL sp_MSupd_TimeSlicesBaseDate'

this is the error we get:

I recently converted a web application of ours to VS 2008 so that we could upgrade to .net 3.51 framework.
I have been making some changes to the layout, to take advantage of ajax and minimize the amout of data needing to be loaded and the number of postbacks processed.
The problem I am having is when I try to save the data.
The page postback calls a local Sub which reads the form data into local variables and then passes these variables to our assembly.
The primary assembly has 70 parameters which are used to populate one of the tables in our database.
So I have 70 local variables just for this call plus a variable reference to the output of the assembly which contains a property for each of the columns in the associated database record.
There are some additional assemblies called to update other tables so, in all there are 121 locally defined variables in this sub.
Bear in mind that this sub is called from the page load event which has 93 of it's own locally declared variables.
Here is what is happening, when I run the code I am using cdate() to convert the value of a text box to datetime and pass it to my assembly. When doing so it throws a conversion error.
So I created a local datetime variable and converted the value of the control to the datetime and passed the variable to the assembly.
No more error, but the proc did not save the data as it was supposed to.
What I noticed in debugging, on the locals tab, is that every local datetime variable displayed the following message:
Cannot evaluate expression because we are stopped in a place where garbage collection is impossible, possibly because the code of the current method may be optimized
I also noticed that on the watch window the same message would display if I attempted to reference any of the datetime controls on the form.
There are only 3 variables and 3 datetime controls that appear to be affected. the controls are all html input boxes. Every other variable and control on the form behaves normally and I can see their values while debugging, it is just these six that are exhibiting the problem, whats more is that they are not new controls to the form.

I have a form on my website which inserts information into a table stored in sql server 2008... when I try to submit the form and I have entered a date like "08/10/2010" it works perfecting... but when trying to enter "24/10/2010" it doesn't work as the default format in SQL server is "mm/dd/yyyy" - so throws up an error saying:
The conversion of a nvarchar data type to a datetime data type resulted in an out-of-range value. The statement has been terminated. Also when I enter the date "08/10/2010" then submit the form, when retreiving that date on another page it displays as "10/08/2010"?

i'd like to be able to check to see if an item with the same id has already been placed in the database, if so to then update the quantity for that item, however due to the fact I have this in a foreach loop it will update the quantity for each item.
When I placed the Command outside of the loop I am unable to use 'ItemID' as it's not in context, is there anyway I can get around this?
foreach (UserItem ItemID in (List<UserItem>)Session["UserSession"])
{
ConclusionPage.InsertCommand = "IF EXISTS (SELECT ItemID FROM tblUserItems WHERE UserID='@CurrentUser' AND ItemID='@ItemID') UPDATE tblUserItems SET Quantity = Quantity+1 WHERE (UserID = '@CurrentUser') AND (ItemID = '@ItemID')";
ConclusionPage.Insert();

I'm using a foreach to loop through an IList of objects in a Partial View in ASP.NET MVC.
Here's the entire code (Message is one of my classes from the Model).
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IList<Message>>" %>
<%
if (ViewData.Model.Count > 0)
{
foreach (MvcTest.Models.Message m in ViewData.Model)
{
Response.Write(m.RenderHtml());
}
}
ie explicitly declaring a variable for the IList rather than just using the (strongly-typed) Model, and it works fine.
