Vista - Set Listbox Value

How can I set the listbox value and retrieve a listbox value with just text?
I have filled the listbox with items in the items collection property (very
simple, just one column of text items).

I will have the text from a database and I know it is in the list. How can I
set it and retrieve it?

Do I need to loop the listbox to find matching text and set that
selectedindex to true.

Any sample code would be appreciated to get the text and set the text.

You're gonna laugh. It's this easy:

namespace ListBoxDemo
{
partialclassForm1
{
///<summary>
/// Required designer variable.
///</summary>
private System.ComponentModel.IContainer components = null;
///<summary>
/// Clean up any resources being used.
///</summary>
///<param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protectedoverridevoid Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code

In a web app the ListBox will be populated with ListItem objects. The Items property of the listbox has a "FindByTest" method that returns a ListItem object that you can set the .SelectedItem property to.

the Listbox allows multiple items to be selected.

Derek,

In the same way as a Combobox

Create a collection by instance a datatable which is the most simple to use
with a listbox

Set that as the DataSource
Set one column to the displaymember
Set another column to the valuemember

You are ready
