 ListBox

 提供了一个选项列表，可以固定或者动态绑定

<StackPanel>

    <GroupBox Margin="5">

        <GroupBox.Header>

            <TextBlock Text="Select SelectionMode"></TextBlock>

        </GroupBox.Header>

        <GroupBox.Content>

            <StackPanel Margin="3" Background="AliceBlue" RadioButton.Checked ="Radio_Checked">

                <RadioButton Name="radioSingle">Single</RadioButton>

                <RadioButton Name="radioMultiple">Multiple</RadioButton>

                <RadioButton Name="radioExtended">Extended</RadioButton>

            </StackPanel>

        </GroupBox.Content>

    </GroupBox>

    <GroupBox Margin="5">

        <GroupBox.Header>

            <TextBlock Text="Effect"></TextBlock>

        </GroupBox.Header>

        <GroupBox.Content>

            <ListBox Name="list">

                <ListBoxItem>Item 1</ListBoxItem>

                <ListBoxItem>Item 2</ListBoxItem>

                <ListBoxItem>Item 3</ListBoxItem>

                <ListBoxItem>Item 4</ListBoxItem>

                <ListBoxItem>Item 5</ListBoxItem>

            </ListBox>

        </GroupBox.Content>

    </GroupBox>

</StackPanel>

private void Radio_Checked(object sender, RoutedEventArgs e)

{

    RadioButton btn = (RadioButton)e.OriginalSource;

    string mode = btn.Name;

    switch (mode)

    {

        case "radioSingle": list.SelectionMode = SelectionMode.Single; break;

        case "radioMultiple": list.SelectionMode = SelectionMode.Multiple; break;

        case "radioExtended": list.SelectionMode = SelectionMode.Extended; break;
