Wpf ListBox數據綁定實例1--綁定字典集合

1.使用ListBox綁定Dictionary字典數據

ListBox經常使用事件SelectionChanged

private void bindListBox()
{
    Dictionary<string, string> dic = new Dictionary<string, string>();
    foreach (var item in Fonts.SystemFontFamilies.OrderBy(q => q.Source))
    {
        dic.Add(item.Source, "---->" + string.Join(",", item.FamilyNames.Select(q => q.ToString())));
        //dic.Add(item.Source,"------");
    }
    listBox.ItemsSource = dic;
}
//選中結果事件
private void listBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    ListBox thisBox = e.Source as ListBox;
    //e.AddedItems   全部選中的結果
    //e.RemovedItems  全部未選中的結果
    //解析結果是 Key Value鍵值對
    KeyValuePair<string, string> item = (KeyValuePair<string, string>)e.AddedItems[0];
}

Xaml

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="57*"/>
        <RowDefinition Height="347*"/>
    </Grid.RowDefinitions>
    <ListBox x:Name="listBox" Grid.Row="1"  SelectionChanged="listBox_SelectionChanged"  />
    <Label x:Name="label" Content="系統字體顯示" FontWeight="Bold"  Foreground="Red" HorizontalAlignment="Left" Margin="36,22,0,0" VerticalAlignment="Top" Height="26" Width="97"/>
</Grid>

2.使用字典集合單項綁定，ListBox.ItemTemplete模板

後臺同上

Xaml定義：

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="21*"/>
        <RowDefinition Height="248*"/>
    </Grid.RowDefinitions>
    <ListBox x:Name="listBox" Grid.Row="1">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="100"></ColumnDefinition>
                        <ColumnDefinition Width="*"></ColumnDefinition>
                    </Grid.ColumnDefinitions>
                    <Label  Grid.Column="0"  Background="LightBlue"  Content="{Binding Path=Key,Mode=OneWay}"/>
                    <TextBox  Grid.Column="1" Text="{Binding Path=Value,Mode=OneWay}"/>
                </Grid>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>
</Grid>

顯示結果：
