在xaml中绑定一个类 [英] Binding a class in xaml

问题描述

嘿伙计们，我被困了......我希望你能帮忙:)

我上课了：

< pre class ="prettyprint"> public class Result
{
public string id {get;组; }
public int time {get;组; }
public用户user {get;组; }
}

和一个可观察的集合作为listbox

 ObservableCollection< Result> NotificationsLst = new ObservableCollection< Result>（）; 
 
 
 private void MainPage_Loaded（object sender，RoutedEventArgs e）
 {
 //将列表设置为列表框的源
 lstboxNotifications.ItemsSource = NotificationsLst; 
} 
 

我有一个带有的UserControl property：

 private Result NotificationResult; 
 public Result ContentNotification 
 {
 get {return NotificationResult; } 
设置
 {
 //这里我使用刚刚设置的数据.. 
 // ... 
 // ... ... 
 // ... 
} 
} 

并试图像这样绑定：

< telerikPrimitives：RadDataBoundListBox.ItemTemplate> 
< DataTemplate> 
< local：elemNotification ContentNotification =" {Binding}" /> 
< / DataTemplate> 
< / telerikPrimitives：RadDataBoundListBox.ItemTemplate> 

但这不起作用？！

它会抛出此错误："System.ArgumentException：[Arg_ObjObjEx]"

可以有人帮忙吗？

Hey guys, i'm stuck... i hope you can help :)

i've got a class:

    public class Result
    {
        public string id { get; set; }
        public int time { get; set; }
        public User user { get; set; }
    }

and a observable collection as source for a listbox

ObservableCollection<Result> NotificationsLst = new ObservableCollection<Result>();


private void MainPage_Loaded(object sender, RoutedEventArgs e)
{
//Setting the list as the source for a listbox
lstboxNotifications.ItemsSource = NotificationsLst;
}

i've got a UserControl with a property:

private Result NotificationResult;
public Result ContentNotification
{
  get { return NotificationResult; }
  set
  {
  //here i work with the data that was just set..
  //...
  //...
  //...
  }
}

and trying to bind like this:

<telerikPrimitives:RadDataBoundListBox.ItemTemplate>
  <DataTemplate>
      <local:elemNotification ContentNotification="{Binding}"/>
  </DataTemplate>                
</telerikPrimitives:RadDataBoundListBox.ItemTemplate>

but that doesn't work?!

it throws this error: "System.ArgumentException: [Arg_ObjObjEx]"

Can anybody help?
