WPF Example: XmlDataProvider & Editable ComboBox

The Code is as follows:

MainWindow. xaml

<Window x:Class="ComboBoxDemo.MainWindow"        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        Title="MainWindow" Height="80" Width="329">    <StackPanel Orientation="Horizontal" Width="304">                <StackPanel.Resources>            <XmlDataProvider x:Key="dataMemberList" XPath="/MemberList">                <x:XData>                    <MemberList xmlns="">                        <Member>                            <Name>Stephone</Name>                            <Id>54765</Id>                        </Member>                        <Member>                            <Name>Alex</Name>                            <Id>32768</Id>                        </Member>                        <Member>                            <Name>Smith</Name>                            <Id>44326</Id>                        </Member>                    </MemberList>                </x:XData>            </XmlDataProvider>        </StackPanel.Resources>                <Label Height="26">Choose/Input member name:  </Label>        <ComboBox Name="memberNameEditor" Height="24" Width="100"                  ItemsSource="{Binding Source={StaticResource dataMemberList}, XPath=Member}"                   DisplayMemberPath="Name"                  IsEditable="True" />        <Button Height="24" Margin="4,0,4,0"                Content="OK"                Click="ButtonOK_Click"/>    </StackPanel></Window>

MainWindow. xaml. cs

using System.Windows;namespace ComboBoxDemo{    /// <summary>    /// Interaction logic for MainWindow.xaml    /// </summary>    public partial class MainWindow : Window    {        public MainWindow()        {            InitializeComponent();        }        private void ButtonOK_Click(object sender, RoutedEventArgs e)        {            MessageBox.Show(this.memberNameEditor.Text);        }    }}

Notes:

1. In XmlDataProvider, you must declare xmlns = ""; otherwise, the XPath search path will become invalid;

2. To make ComboBox editable, set IsEditable = "True ".
