绑定的ItemsSource编程 [英] Binding ItemsSource programmatically

问题描述

什么是这在C＃code等价？

 ＆LT; ListView控件
    X：NAME =taskItemListView
    的DataContext ={结合的SelectedItem，的ElementName = itemListView}
    的ItemsSource ={结合taskItems}＆GT;
...
＆LT; /＆的ListView GT;
 

我试过以下code，但它似乎不工作...

 绑定B =新的Binding（）;
b.Path =新的PropertyPath（taskItems）;的DependencyProperty DP = DependencyProperty.Register（的ItemsSource的typeof（对象）的typeof（对象），NULL）;
BindingOperations.SetBinding（taskItemListView，DP，B）;
 

修改

基于@ sa_ddam213的回答

，这个工作：

 绑定dataContextBinding =新的Binding（）;
dataContextBinding.Path =新的PropertyPath（的SelectedItem）;
dataContextBinding.Source = itemListView;
BindingOperations.SetBinding（taskItemListView，ListView.DataContextProperty，dataContextBinding）;结合sourceBinding =新的Binding（）;
sourceBinding.Path =新的PropertyPath（taskItems）;
BindingOperations.SetBinding（taskItemListView，ListView.ItemsSourceProperty，sourceBinding）;
 

解决方案

这样的财产以后应该工作：

  BindingOperations.SetBinding（taskItemListView，ListView.DataContextProperty，新的绑定（的SelectedItem）{源= itemListView}）;
BindingOperations.SetBinding（taskItemListView，ListView.ItemsSourceProperty，新的绑定（taskItems）{源=此}）;
 

请注意：源=这个这个等于持有该类别的 taskItems ，的SelectedItem

What is the equivalent of this in c# code?

<ListView
    x:Name="taskItemListView"
    DataContext="{Binding SelectedItem, ElementName=itemListView}"
    ItemsSource="{Binding taskItems}">
...
</ListView>

I've tried the following code, but it doesn't seem to work...

Binding b = new Binding();
b.Path = new PropertyPath("taskItems");

DependencyProperty dp = DependencyProperty.Register("itemsSource", typeof(object), typeof(object), null);
BindingOperations.SetBinding(taskItemListView, dp, b);

Edit:

Based on @sa_ddam213's answer, this worked:

Binding dataContextBinding = new Binding();
dataContextBinding.Path = new PropertyPath("SelectedItem");
dataContextBinding.Source = itemListView;
BindingOperations.SetBinding(taskItemListView, ListView.DataContextProperty, dataContextBinding );

Binding sourceBinding = new Binding();
sourceBinding.Path = new PropertyPath("taskItems");
BindingOperations.SetBinding(taskItemListView, ListView.ItemsSourceProperty, sourceBinding );

解决方案

Somthing like this should work:

BindingOperations.SetBinding(taskItemListView, ListView.DataContextProperty, new Binding("SelectedItem") { Source = itemListView});
BindingOperations.SetBinding(taskItemListView, ListView.ItemsSourceProperty, new Binding("taskItems") { Source = this });

Note: "Source = this" this equals the class that is holding the taskItems, SelectedItem
