        <ListBox Width="300" Height="200">
            <StackPanel x:Name="sp">

            </StackPanel>
        </ListBox>
        <Button Width="120" Height="30" Margin="50,12,230,258" Content="GetSelectedValue" Click="Button_Click"></Button>

    </Grid>
</UserControl>ide

CheckBox的獲取orm

public partial class MyListBox : UserControl
    {
        public MyListBox()
        {
            InitializeComponent();
            for (int i = 0; i < 10; i++)
            {
                CheckBox cb = new CheckBox();
                cb.Content = "cb" + i.ToString();
                sp.Children.Add(cb);
            }
        }xml

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            aaa.Text = "";
            foreach (CheckBox c in sp.Children)
            {
                if (c.IsChecked == true)
                {
                    aaa.Text += c.Content.ToString() + ",";
                }
            }
        }
    }get

RadioButton的獲取string

public partial class MyListBox : UserControl
    {
        public MyListBox()
        {
            InitializeComponent();
            for (int i = 0; i < 10; i++)
            {
                RadioButton rb = new RadioButton();
                rb.Content = "rbtn" + i.ToString();
                sp.Children.Add(rb);
                          }
        }it

private void Button_Click(object sender, RoutedEventArgs e)
{io

aaa.Text = "";

            foreach (RadioButton rb in sp.Children)
            {
               if (rb.IsChecked == true)
              {
                   aaa.Text = rb.Content.ToString();
              }form

}class

方法二：

<Grid x:Name="LayoutRoot" Background="White">
        <ListBox x:Name="MyFeatures" Width="300" Margin="41,30,59,151">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <RadioButton GroupName="rbtn" Content="{Binding}" Checked="RadioButton_Checked"></RadioButton>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
        <ListBox x:Name="MyCheckBox" Width="300" Margin="41,155,59,32">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <CheckBox Content="{Binding}" Checked="CheckBox_Checked" Unchecked="CheckBox_Unchecked"></CheckBox>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
        <TextBlock x:Name="aaa" Text="123" Height="30" Margin="80,12,30,258"></TextBlock>
        <Button Width="30" Height="30" Margin="358,258,12,12" Content="aaa" Click="Button_Click"></Button>
    </Grid>
            }
                               }
    }

List<string> list = new List<string>();

        public SilverlightListBox()
        {
            InitializeComponent();
            for (int i = 0; i < 6; i++)
            {
                list.Add("zhangsan"+i.ToString());
            }
            MyFeatures.ItemsSource = list;
            MyCheckBox.ItemsSource = list;
        }
        List<string> listcheck = new List<string>();
        private void RadioButton_Checked(object sender, RoutedEventArgs e)
        {
            aaa.Text = (sender as RadioButton).Content.ToString();
        }

        private void CheckBox_Checked(object sender, RoutedEventArgs e)
        {
            listcheck.Add((sender as CheckBox).Content.ToString());
        }

        private void CheckBox_Unchecked(object sender, RoutedEventArgs e)
        {
            listcheck.Remove((sender as CheckBox).Content.ToString());
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            aaa.Text = "";
            for (int i = 0; i < listcheck.Count; i++)
            {
                aaa.Text += listcheck[i].ToString() + ",";
            }
        }

方法三：

public ListBoxGrid()
        {
            InitializeComponent();
            for (int i = 0; i < 10; i++)
            {
                RowDefinition row = new RowDefinition();
                row.Height = new GridLength(20);
                Layout.RowDefinitions.Add(row);

                CheckBox cb = new CheckBox();
                cb.Content = "checkb" + i.ToString();
                cb.SetValue(Grid.RowProperty, i);//設置這個才能夠正確排列
                Layout.Children.Add(cb);
            }
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            aaa.Text = "";
            foreach (CheckBox c in Layout.Children)
            {
                if (c.IsChecked == true)
                {
                    aaa.Text += c.Content.ToString() + ",";
                }
            }
        }

                RadioButton rb = new RadioButton();
                rb.Content = "rbtn" + i.ToString();
                rb.SetValue(Grid.RowProperty, i);
                Layout.Children.Add(rb);
            }
        }

private void Button_Click(object sender, RoutedEventArgs e) { aaa.Text = ""; foreach (RadioButton c in Layout.Children) { if (c.IsChecked == true) { aaa.Text += c.Content.ToString() + ","; } } }
