WPF, Template Select 하기

C# WPF, 지난번 포스트 소스에 연결됩니다.

상황에 따라, 표시되는 템플릿이 자동으로 지정되게끔 만들 수 있네요.

SubjectSelectDataTemplate.cs

using System.Windows;

using System.Windows.Controls;

 

namespace WPF_MVVM_SAMPLE01

{

    public class SubjectSelectDataTemplate : DataTemplateSelector

    {

        public override DataTemplate SelectTemplate(object item, DependencyObject container)

        {

            Score score = item as Score;

            FrameworkElement el = container as FrameworkElement;

            return (DataTemplate)el.FindResource(score.SCORE > 60 ? "DataTemplate3" : "DataTemplate4");

        }

    }

}

TemplateSelectWindow.xaml
