我知道在XAML中,可以使用代码创建数据模板,这样您就可以设置样式。根据自己的喜好绑定控件:
<ListBox x:Name="statusBox">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Grid x:Name="ListBoxItemLayout" >
<StackPanel>
<TextBlock x:Name="time" Style="{StaticResource PhoneTextNormalStyle}" Margin="0" Width="462" Text="{Binding time}" FontSize="16" FontWeight="Bold"/>
<TextBlock x:Name="status" Style="{StaticResource PhoneTextNormalStyle}" Margin="0" Width="462" Text="{Binding status}" TextWrapping = "Wrap" Height="85" HorizontalAlignment="Left" VerticalAlignment="Top"/>
</StackPanel>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
public class status
{
public string time{ get; set; }
public string statusText{ get; set; }
}
List<status> list = new List<status>();
status aStatus = new status() { time="3:00pm", statusText="this is a status" };
list.Add(aStatus);
statusBox.ItemsSource = list;
但是,在我的最新项目中,我有一个动态添加项目/页面的数据透视控件,因此我无法在页面上定义任何xaml。这有什么解决方法吗?
我希望能够做的只是通过c#代码创建数据模板,这样我就可以在我的应用程序中实例化一个新控件。
List<status> list = new List<status>();
statusBox lb = new statusBox(); // <-------------------- look here
status aStatus = new status() { time="3:00pm", statusText="this is a status" };
list.Add(aStatus);
list.Add(aStatus);
lb.ItemsSource = list;
PivotItem pi = new PivotItem();
pi.Content = lb;
Pivot pivot = pivot1;
pivot.Items.Add(pi);
是否可以通过这种方式创建自定义控件?如果是这样,怎么样?

首先,在电话资源部分创建一个DataTemplate
<phone:PhoneApplicationPage.Resources>
<DataTemplate x:Name="listBoxTemplate">
<Grid >
<StackPanel>
<TextBlock Style="{StaticResource PhoneTextNormalStyle}" Margin="0" Width="462" Text="{Binding time}" FontSize="16" FontWeight="Bold"/>
<TextBlock Style="{StaticResource PhoneTextNormalStyle}" Margin="0" Width="462" Text="{Binding statusText}" TextWrapping = "Wrap" Height="85" HorizontalAlignment="Left" VerticalAlignment="Top"/>
</StackPanel>
</Grid>
</DataTemplate>
</phone:PhoneApplicationPage.Resources>
然后在codebehind文件中使用以下代码动态生成ListBox
ListBox lb = new ListBox() { Name = "statusBox" };
lb.ItemTemplate = this.listBoxTemplate;
List<status> list = new List<status>();
status aStatus = new status() { time = "3:00pm", statusText = "this is a status" };
list.Add(aStatus);
list.Add(new status() { time = "4:00pm", statusText = "this is another status" });
lb.ItemsSource = list;
this.ContentPanel.Children.Add(lb);
