本文介绍了用字符串数组填充 WPF 列表框的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着跟版网的小编来一起学习吧!
问题描述
而不是像这样将字符串数组 m_List
中的每一项添加到 ListBox destinationList
中:
Instead of adding each item one by one to the ListBox destinationList
from the string array m_List
like this:
foreach (object name in m_List)
{
destinationList.Items.Add((string)name);
}
有没有更好的办法?
我不想将数据绑定到destinationList,因为我想稍后从ListBox中删除一些条目.
I don't want to bind the data to the destinationList since I want to delete some entries from the ListBox later on.
推荐答案
HTH:
string[] list = new string[] { "1", "2", "3" };
ObservableCollection<string> oList;
oList = new System.Collections.ObjectModel.ObservableCollection<string>(list);
listBox1.DataContext = oList;
Binding binding = new Binding();
listBox1.SetBinding(ListBox.ItemsSourceProperty, binding);
(listBox1.ItemsSource as ObservableCollection<string>).RemoveAt(0);
只需使用 (ItemSource as ObservableCollection)... 来处理项目,而不是 Items.Add 等.
Just use (ItemSource as ObservableCollection)... to work with items, and not Items.Add etc.
