want to create a list representing a list of valid locations on a grid. Items can only be stored in these valid locations and I want to locate the "next available" valid location. If I do this with a traditional list I have to deal with the end of list conditions. A circular list collection would make this a bit easier. Is there such a collection in .net?

I want to do the front end in a way which will show a table with each row showing a label and textbox. This would be too simple to do obviously but I want it to show 4 rows of the table by default and then the user can select "add another" this will then add another row onto the table with a label and textbox exactly similar to the 4 default. Everytime the user selects "add another" the table increments by 1.
How to setup a multi value dropdownlist from a list collection...
Datasource: Listcollection which contains ColorCode and Description...
how to I setup a dropdown with Colorcode-Description like ORG-orange...
then how to capture these selected value as colorcode only by removing description for update purpose...
Now I am doing like this...
ddl.datesource=list ...contains (colorcode, description)
ddl.DataTextField = "ColorCode";
ddl.DataValueField = "ColorCode";
ddl.databind();
then selected value should be like this...
ddlcolor.Items.FindByValue((DataBinder.Eval(formView1.DataItem, "colorCode").ToString())).Selected = true;
for update:
ClassA.Color= ddl.selectedvalue();
Now what I need change to in the above code to get the combination of both..otherwise i need have textbox for description which syncs with ddl..which is bit complex for my level of programming.

We need to create a simple web service in ASP.NET that can be called from PHP or other languages. This in turn will be used to update records in a database for an item submission.
The core part is fairly simple, we have a base set of fields for the object - first name, last name, birth date, city, etc. In addition however we need to accept a list of items associated with that object that can range from 0-n.

What would be the best way to structure this so it can be easily passed to the ASP.NET web service and processed as a single call for the entire object? Would passing the list of items as a single delimted string be a wise approach? Ex: Jan 1 2009, ABC|May 1 2010, 123|Jun 30 2010, XXXXX
I'm using forms authentication in my C# based web site, with the authentication defined in web.config files in the various folders/sub-folders. I want to write a generic administration menu system, that lists all of the admin pages that the use is authorized to open. As I add pages, I want them to automatically show up in the menu. I need to obtain a list/collection of all pages that the active user is authorized to open. Is this possible in ASP.Net 3.5?
View 2 RepliesI have a list item collection. How to add this list item collection to a datatable.
The list item collection has the following fields:
Student Name, Maths Mark
John 20
Mac 30
John 35
I want to create a html table from the data table, which is grouped on the Student Name field.
I was building an application for a project with .NET 3.5 and I noticed a weird behaviour of the List.Add method:
I have built my own class to organize data pulled from a database, and I use a while cycle to iterate through it.
However, when I List.Add(item), the whole content of the list is substituted with the last content pulled.
An example:
Suppose you have 3 users in a DB, each one identified with an ID and a username:
| ID | username |
| 1 | John |
| 2 | Fred |
| 3 | Paul |
and you have a "Users" class defined as
public class Users
{
private Int32 iD;
private String username;
public Int32 ID
{
get { return iD; }
set { iD = value; }
}
public String Username
{
get { return username; }
set { username = value; }
}
}
So you write this function:
[... SQL definitions - sdr is a SqlDataReader ...]
List<Users> userlist = new List<Users>();
if (sdr.HasRows) //There are users
{
Users user = new Users();
while (sdr.Read())
{
user.ID = sdr.GetInt32(0);
user.username = sdr.GetString(1);
userlist.Add(user);
}
}
What you expect (I expect) is userlist containing:
| ID | username |
| 1 | John |
| 2 | Fred |
| 3 | Paul |
What I actually get is, instead
| ID | username |
| 3 | Paul |
| 3 | Paul |
| 3 | Paul |

I am trying to return an Entity Framework 4 object with children to an jQuery JSON AJAX function but I get a circular reference error - in short my method looks like this
[WebMethod]
public static JSONObject Get()
{
WebHelper.JSONObject lJSONObject = new WebHelper.JSONObject();
lJSONObject.Object = Repository.Parent.Include("Child.Child").FirstOrDefault();
return lJSONObject;
}
if I do not include children the functions works fine, but with children the circular reference occurs.
When I re/build my ASP.NET website I do not receive any errors. However when I PUBLISH the site, it gives me a 'Circular file references are not allowed.' error.
I read a little on the web about this, and it provided a batch='false' option, which I tried and does nothing.
The page, has a master page, which may call on the same control twice; however, this control does not refer back to anything
When I try to depoly my web project then it throws an exception as "Circular References not allowed" Those are two same exceptions for my template.master and Forummaster.master file. When I build my code then very rarely it throws an exception but I can not deploy my web project because for deployment everytime it throws same exceptions at the time of building web project for deployment.
View 1 RepliesI am trying to create a set of WCF web services for an existing website that uses web site instead of a web application project. I would like to create a DLL that I drop into the Bin folder instead of writing all my code inside the App_Code directory. Ideally, I want to create a project and reference it from the web site, but I am running into a difficult situation.
The DLL will need to reference configuration and other DLLs located inside the bin folder of the website causing a circular reference. How do I get around this issue?
I have a service layer with a logger class
Service layer references DAL for Logger class to get its email credentials to use while sending email for critical log items.
I want to use this logger inside the DAL since there is stuff that needs to be logged there also - but with my current architecture I cannot.
I see this could somewhat be handled via IOC but my concern with that is if that way I will be addressing the root of the problem, or hiding it using another layer of abstraction.
I have a list of objects that I want to bind to a gridview. Creating that list and binding it works fine for most of the public properties in that list.
There are some objects contained in each of those objects... for instance there is an Address object.
object.Address.Line1;
object.Address.Line2;
When I bind this to my gridview, I have no issues with stuff like object.DateRegistered, but how can I access things like object.Address.WhatEverProperty? I always get this error:
"A field or property with the name 'xxx.xxxx' was not found on the selected data source."

I want to know that how i use the collection class for storing some data and save it letter in the data base.
