.net Have Circular List Collection?

Jan 5, 2010

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?

C# - Storing A Collection Into A List And Session - Front End

Jan 29, 2011

I have this program in which I am trying to store a collection of values into a list and session


valueCollection = (List<Values>)Session["Value"];

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.

Web Service - Passing A Base Object With List / Collection?

Apr 9, 2010

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.

Jan 1 2009, ABC
May 1 2010, 123
Jun 30 2010, XXXXX

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

Iterating System.Collection.Generic.List.Add Does Not Work As Expected?

Mar 7, 2010

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);

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 |

Forms Data Controls :: Bind A Collection Within A Collection To A Gridview?

Jul 26, 2010

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.



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."

Add Controls To A Collection And Update From Collection?

Mar 25, 2011

I have an ASP.NET app with lots of textboxes all over the page that need updating at various points through program execution.

These textboxes actually belong to a certain class, so for easy updating I thought I could create a Dictionary(Of string, object) and add the control.ID and the control to it and then for updating do something like this:

(in case of updating textbox.text):


However the text property of the textbox does not actually get updated. I'm mainly trying to avoid having to manually do textbox.text = somestring for each one of my textboxes every time I have to update them.

C# - Array, Dictionary Or List In A Session?

Feb 5, 2010

What would be the most efficient way of storing a set of values in a session? I'm guessing it's either a List/Array or Dictionary. Basically, when a user selects an item from a DropDownList, a value (between 1 and N where N <= 20) is sent back to the server. I'd then like this value to be used as an index (if using arrays) or key (if using a dictionary) within the session. I don't want the value to be seen by the user, hence why it's not stored in the DDL. From what I gather, dictionaries are designed for key-lookups. However, since the scale is quite small, are there any overheads of using a dictionary that could make it less efficient in this case? Each corresponding value is unique to the user, so I've decided to use sessions.

I'd like the drop down text to take the following format:

Test1 - Count: 123
Test2 - Count: 321

I was going along the following path with no luck:

MyDropDown.DataTextFormatString = string.Format("{0} - Count: {1}", Key, Value);
