如何在代码中写这个xaml [英] How Write this xaml in code

问题描述

< CollectionViewSource x：Key =" workConditions"

  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;
来源=" {Binding WorkConditions}" />

其中  WorkConditions some List< class>

  var workConditionsViewSource = new CollectionViewSource（）;

  var binding = new Binding（" WorkConditions"）;

  &NBSP; &NBSP; &NBSP; &NBSP;  

  &NBSP; &NBSP;的&NBSP; &NBSP; &NBSP; workConditionsViewSource.Source = binding; //例外

解决方案

嗨Ahlompys，

根据你的描述，你想通过后面的代码使用CollectionViewSource，我使用ListView做一个你可以看一下的样本：

< ListView Name = QUOT; ListView1的"> 
< ListView.View> 
< GridView> 
< GridViewColumn 
 Width =" 100" 
 DisplayMemberBinding =" {Binding Id}" 
 Header =" Id" /> 
< GridViewColumn 
 Width =" 100" 
 DisplayMemberBinding =" {Binding name}" 
 Header =" name" /> 
< / GridView> 
< /ListView.View> 
< / ListView> 

 public partial class Window12：Window 
 {
 public ObservableCollection< model12>模型{get;组; } 
 
 public Window12（）
 {
 InitializeComponent（）; 
 models = new ObservableCollection< model12>（）
 {
 new model12（）{Id = 1，name =" cherry"}，
 new model12（）{Id = 2，name =" mattew"}，
 new model12（）{Id = 3，name =" barry"}，
 new model12（）{Id = 4，name =" cole" }，
 new model12（）{Id = 5，name =" annine"}，
 new model12（）{Id = 6，name =" alex"}，
 new model12 （）{Id = 7，name =" wendy"}，
 
}; 
 CollectionViewSource childCollection = new CollectionViewSource（）; 
 childCollection.Source = models; 
 Binding binding = new Binding（）; 
 binding.Source = childCollection; 
 BindingOperations.SetBinding（listview1，ListView.ItemsSourceProperty，binding）; 
 
} 
} 
 
 public class model12 
 {
 public int Id {get;组; } 
公共字符串名称{get;组; } 
} 

最好的问候，

Cherry

<CollectionViewSource x:Key="workConditions"
                              Source="{Binding WorkConditions}"/>

Where WorkConditions some List<class>

 var workConditionsViewSource = new CollectionViewSource();
 var binding = new Binding("WorkConditions");
           
            workConditionsViewSource.Source = binding; // exception

解决方案

Hi Ahlompys,

According to your description, you want to use CollectionViewSource by code behind, I use ListView to do one sample that you can take a look:

 <ListView Name="listview1">
            <ListView.View>
                <GridView>
                    <GridViewColumn
                        Width="100"
                        DisplayMemberBinding="{Binding Id}"
                        Header="Id" />
                    <GridViewColumn
                        Width="100"
                        DisplayMemberBinding="{Binding name}"
                        Header="name" />
                </GridView>
            </ListView.View>
        </ListView>

 public partial class Window12 : Window
    {
        public ObservableCollection<model12> models { get; set; }
        
        public Window12()
        {
            InitializeComponent();
            models = new ObservableCollection<model12>()
            {
                new model12(){Id=1,name="cherry"},
                new model12(){Id=2,name="mattew"},
                new model12(){Id=3,name="barry"},
                new model12(){Id=4,name="cole"},
                new model12(){Id=5,name="annine"},
                new model12(){Id=6,name="alex"},
                new model12(){Id=7,name="wendy"},

            };
            CollectionViewSource childCollection = new CollectionViewSource();
            childCollection.Source = models;
            Binding binding = new Binding();
            binding.Source = childCollection;
            BindingOperations.SetBinding(listview1, ListView.ItemsSourceProperty, binding);

        }
    }

    public class model12
    {
        public int Id { get; set; }
        public string name { get; set; }
    }
