I have a generic List method that returns sales units, retail amount and their totals need to be displayed on a web page. For example here are 3 sales records, comments in the code below is where it needs the totals calculated and returned to the list.
public List<SaleSize> List()
{
List<SaleSize> sz = new List<SaleSize>();[code]....
I am not sure but will I need a foreach to loop through all the records?
I want to create a web method that accepts a List of custom objects (passed in via jQuery/JSON). When I run the website locally everything seems to work. jQuery and ASP.NET and everyone is happy.

System.InvalidOperationException: EditCustomObjects Web Service method name is not valid.

I have a Method that returns 4 records like this.
Name: Test1
Year: 2010
Value: $1000
Name: Test2
Year: 2010
Value: $1000
Name: Test3
Year: 2011
Value: $2000
Name: Test4
Year: 2011
Value: $1000
I need a way to get the unique years just ( 2010, 2011) rather than all 4 years, rest of the data could be duplicates.
Here is the method:
public List<TestCosts> GetTestvalues(string testid)
{
List<TestCosts> testlist = Testscores.List(testid);
return testlist;
}
Most of the examples of removing duplicates I saw have a list of one item only but in my case I have 3 items per record and I need to loop through each record, find the duplicate years, remove them and then return the distinct list of years along with the other data.

In one of the methods I'm using in my MVC app, there's a param that accepts a list collection of strings. If I have a string parameter, I can give it a default value of an empty string, but I cannot seem to give the list collection a default value of a new, empty list collection. I get the error that's beginning to seriously grate on my nerves about requiring a compile-time constant. getting the generic list to work with a default empty set?
View 5 RepliesI have a gridview of jobTable which has a checkbox "IsTop" (a bit column inside jobTable), which means they will be listed at the top in the list of "latest job postings". Which is the best way to implement this function? My idea is to ensure if 1 row "IsTop" checked, all other checkBox assocated with other rows will become invisible, and find that JobID as the startRowIndex. But how do I write that code?
View 2 RepliesI have a table with 4 columns: ID, signId, storeNum, quantity with ID, SignId, and storeNum as composite primary keyif storeNum is -1, that means the quantity is the default quantity. If a store has a store-specific quantity, the storeNum is this store's number.
I need to show all rows that have specific quantity for a store, and all rows that have default quantity and of which the store does not have store-specific quantity
currently I use table-value function with storeNum as parameter to return the list. first, I get all rows that have specific quantity for a store; then, I use cursor to loop through all rows that have default quantity and check each row if the store has a specific quantity. It takes 9 seconds to run the function for a store.
The function is called within a stored procedure, which in turn is called by a function in a class, which in turn is called by a aspx code behind file. It takes about 20 seconds to load the page. 20 seconds to load a page is too long. I am trying to improve
the performance.
I wonder if there is an alternative method to the cursor to get the second part of the list.
Im trying to test my extension method that converts a list of strings in a string comma separated:
public static class Extensions
{
public static string ToCommaString<T>(this IList<T> input)
{
StringBuilder sb = new StringBuilder();
foreach (T value in input)
{
sb.Append(value);
sb.Append(",");
}
return sb.ToString();
}
public void TestExtension()
{
IList test=new List<string>();
//test.ToCommaString doesnt appear
}
}
The issue is that in the method TestExtension i cant use ToCommaString method. Do you know what's happening?
Could i make available for all my web application this extension method registering in web.config or something similar?
I don't know what I'm making wrong.I have a submit button, and on click it should execute the funktion in the code behind, but I get the error that the funktion is undefined.this is my code in the .aspx webform:
<%@ Page Language="C#" AutoEventWireup="True" MasterPageFile="~/DashMaster.master" CodeBehind="BI_MDR.aspx.cs" Inherits ="BI_MDR.StoredProc"%> [code].......
I am creating an Asp.net web site which will support dynamic data. When I am creating a dynamic web site from Scratch (from template in VS) all is working fine. But when I am trying to add dynamic entity (.edmx) file and running the application I am getting following error
"The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'. "
How to solve this error? Error message is "BC30289: Statement cannot appear within a method body. End of method assumed.".
View 1 RepliesI have built a WCF Service that is being consumed by a Silverlight app. At first I created one method that was very simple:
public String SfTest()
{
return "SF Test";
}
No poblem. My silverlight app references my service and displays "SF Test" in a textbox. Now I add a method to my wcf service like this:
public List<String> GetTest()
{
List<String> list = new List<string>();
String a = "a";
list.Add(a);
String b = "b";
list.Add(b);
return list;
}
I update the reference to the service in my Silverlight app and the using statement in my xaml cs page throws an error like the service doesn't even exist although it is there. I am assuming the problem has to do with datatypes or serialization or something like that but it is driving me up the wall. Why can't I consume a simple generic list in my Silverlight app through the WCF service.
We have a web project that contain its business methods in a class library project called "Bll.dll"
some methods of Bll.dll return List<> ... from a source - that i don't remember now - told that returning Collection<> is better than returning List<> Is it a valid ? Note that i don't make any process on values returned from BLL methods .. just view it in a web page
How to loop through the table from vb.net asp.net to update the balance Column. I need the required result below for updating balance column.

I have created a GuestBook-like database and what I want to do is to have in a Formview the total number of posts that the authenticated user has submitted. I have added a formview and a slq control but it seems that the query I have built doesn't work. Do you have any clue? the query is like: SELECT COUNT (Trips_Id) AS VIAGGI FROM Trips WHERE UserId@UserId Do you think this query is correct or there is something missing here or something that I need to add in the code behind?
