DataTemplate

.使用DataTemplateSelector

 // Summary:
    //     Provides a way to choose a System.Windows.DataTemplate based on the data
    //     object and the data-bound element.

 

创建一个继承该类的子类，在SelectTemplate方法中指定使用哪个DataTemplate

 public class PlaceTemplateSelector : DataTemplateSelector
    {
        private DataTemplate washingtonTemplate;

        public DataTemplate WashingtonTemplate
        {
            get { return washingtonTemplate; }
            set { washingtonTemplate = value; }
        }

        private DataTemplate notWashingtonTemplate;

        public DataTemplate NotWashingtonTemplate
        {
            get { return notWashingtonTemplate; }
            set { notWashingtonTemplate = value; }
        }

        public override DataTemplate SelectTemplate(object item, DependencyObject container)
        {
            Place place = (Place)item;

            if (place.State == "WA")
            {
                return washingtonTemplate;
            }
            else
            {
                return notWashingtonTemplate;
            }
        }
    }

在SDK中可以找到该类的使用方法：WPFSamples\ConnectedData\DataTemplatingIntro
