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 drop down list that has the initials of about 12 of our sales guys.How can I make it so that when they select their initials from the list, the next drop down list only shows their customers.In my database there is a column for customer name and salesman.
I have drop down list box that I would like to show two columns, is this possible? Or can it be done with a list box?The query correctly retrieves all of the table data to be displayed, one colum is an abbreviation, the other a bit longer description.

i have an string data array which contains data like this
5~kiran 2~ram 1~arun 6~rohan
now a method returns an value like string [] data public string [] names()
{ return data.Toarray() } public class Person { public string Name { get; set; } public int Age { get; set; } ) List<Person> persons = new List<Person>(); string [] names =names();
now i need to copy all the data from an string array to an list<person> and finally bind to grid view
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 want to pass the Array ( object[]) or Structure data type value to the store procedure through ibatis .net. I can do same by commandtext using SQLDBType.Structure. I am using Table value function in sql server 2008 and .Net 2010.
I have a drop down list that populates information about the product from an access database (vb) when the user makes a selection. would like to have minimal product info on the home page so when the user selects the button for example 'view details' they will be taken to the product screen with the item already selected in the drop down list and information showing.
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 ) > [code]...
I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. 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; } }
