WPF ListBox - how to put values from dataTable?

Question

Hello, I have ListBox and want to put values in this listbox from DataTable:

listBoxVisibleFields.DataContext = SelectedFields;

Where SelectedFields is a DataTable filled with data. But this code does not work. My listbox is empty. As i remember, in WinForms was sucha a thing for list box like ValueMember and DisplayMember, but in WPF I dont find something like that...Does someone know how to fill simply my listbox from DataTable?

Answer 1

The property you are looking for is ItemsSource instead of DataContext. The property most closely resembling ValueMember is called SelectedValuePath (see this example). The analogon for DisplayMember is called DisplayMemberPath.

EDIT: So, your code should look like this:

DataTable SelectedFields = ...;
listBoxVisibleFields.SelectedValuePath = "myID";
listBoxVisibleFields.DisplayMemberPath = "myTextField";
listBoxVisibleFields.ItemsSource = SelectedFields.DefaultView;

Alternatively, the two path values can be set in XAML

<ListBox ... SelectedValuePath="myID" DisplayMemberPath="myTextField" />

which is a bit more elegant.
