C# - How To Add A Data Object Of A Class Array To A Drop Down List
Oct 12, 2010
I have an array for type Person
Person[] Traders = GetTraders();
Person class contains data objects such as first name, last name etc.
I want to add all first names to a dropdownlist. How can i do that? I tried doing it like this, but it won't get the first names:
ddl_traders.DataSource = traders;
EDIT
Person has the following string fields: FirstName, LastName, login.
I want the dropdownlist to display FirstName, but the value has to be the logins. I'm fairly certain that is possible, although I have no idea how it can be done.

I have a Google spreadsheet that I am reading data from and I want to load the data into a list object so I can use but I am having some issues.
Google Spreadsheet
-Worksheet name: Charts
-Tab: Color_Summarized
-Column 1: ColorSummary
-Column 2: ChildID
-Column 3: ParentID
sample rows:
Aqua|29|28
Blue|49|23
Yellow|55|28
My results are
Yellow Color_Summarized FH 55 28
How do I need to set it up so it keeps all the data loaded instead of just the last instance? Is there a better way then putting in class?
My code:
Code:
Imports Microsoft.VisualBasic
Imports System.Data
Imports System.Collections.Generic
Imports Google.GData.Spreadsheets

I am looking here to find a quick and easy way to bind a list of checkbox list items when the postback occurs in the model. Apparently the common way to do it now seems to do it like this form.GetValues("checkboxList")[0].Contains("true"); It seems painfull and not exactly safe. Is there a way to bind a list of checkbox (that are created with or without an helper in the view) or even an array of data for that matters during the UpdateModel(myViewModel, form.ToValueProvider()); phase which would populate an IList<string> or string[] inside of the model ?

I have a table Person (in my database) which has fields like PersonID, PersonName, PersonSurname, etc. What I'd like to do is to bind the PersonName + PersonSurname (e.g. Mark Black) as values for displaying the data in drop down list and PersonID as the data identifier.
As I'm still new with Entity Framework I'm not sure how to manage to do it.

In this code you can see the select statement that the customers are selected for display to the user. Order by is at least being used to disply in name order. but this example here is one of several similar dropdowns. I would like that if they picked one customer then the next view show should be the same customer
<
order by customername
"
asp:SqlDataSource
ID="Customers"
runat="server"
ConnectionString="<%$
ConnectionStrings:SecurityDB_20101025ConnectionString %>"
SelectCommand="SELECT
* FROM [Customers] WHERE ([CustomerId] = ISNULL(@CustomerId, '') OR @IsSuperAdmin = 1 )

But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement
{
public IEnumerable<selectListItem> InactiveProduct { get; set; }
public string[] InactiveProductSelected { get; set; }
public IEnumerable<selectListItem> ActiveProduct { get; set; }
}
