Clone Grid Windows Phone 8

我有一个网格模板在XAML CODE:

<Grid x:name="gridTemplate>
Childrens...
</Grid>

现在我想把这个网格放在LongListSelector in foreach loop:

foreach(var item in myList)
{
   clonedGrid= ??? (need clone here my xaml control)
   longlistselector.Items.Add(clonedGrid):
}

这适用于我的WPF:

 public static class ExtensionMethods
{
    public static T XamlClone<T>(this T original)
        where T : class
    {
        if (original == null)
            return null;
        object clone;
        using (var stream = new MemoryStream())
        {
            XamlWriter.Save(original, stream);
            stream.Seek(0, SeekOrigin.Begin);
            clone = XamlReader.Load(stream);
        }
        if (clone is T)
            return (T)clone;
        else
            return null;
    }
}

如何在WINDOWS PHONE 8中实现此功能?

我会做一个contentControl，在那里我可以把dataTemplate从资源，像这样:

xaml 

<phone:PhoneApplicationPage.Resources>
    <DataTemplate x:Key="MyGrid">
        <Grid>
            <!-- here is your data template, where you can bind to item's properties -->
        </Grid>
    </DataTemplate>
</phone:PhoneApplicationPage.Resources>
cs 

foreach (var item in myList)
{
     ContentControl control = new ContentControl();
     control.Content = item;
     control.ContentTemplate = Resources["MyGrid"] as DataTemplate;
     longlistselector.Items.Add(control);
}

如果你的Grid没有很多属性设置，那么只需创建一个方法来创建新的Grid并将其作为参数传递给你的旧Grid，这样你就可以将所有属性设置为相同的。

public Grid CloneGrid(Grid input)
{
Grid temp = new Grid();
temp.Width = input.Widht;
... etc
return temp;
}

编辑:另一种方法是将属性定义为App.xaml中的Style，然后将其应用于Grid:

Grid.Style = App.Current.Resources[StyleKey] as Style;
