排序的ObservableCollection [英] Sorting ObservableCollection

问题描述

假设我有的ObservableCollection Employee类的

Suppose I have ObservableCollection of employee class

public ObservableCollection<Employee> employeeCollection = new ObservableCollection<Employee>();

public class Employee
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public double MobileNumber { get; set; }
    public string City { get; set; }
    public int Age { get; set; }

    public Employee() {}
}

现在我想排序的的ObservableCollection （employeeCollection） 通过适当地选择从组合框用户[这将是... .Sort通过名字...... .Sort通过移动电话号码等..] ..

now I am trying to sort the ObservableCollection ("employeeCollection") by appropriate selection by user from combobox[it will be….Sort By FirstName….Sort By MobileNumber etc…]..

和它需要的找回排序观察的集合......。 意味着它的不应该在VAR的形式，它应该是 的ObservableCollection＆LT;员工＆GT;

and it is required to get back sorted observable collection…. Means it should not be in form of "var" it should be ObservableCollection<Employee>

所以，我可以分配回它的ItemsSource的ItemsControl的 ...

So I can assign back it to "ItemsSource" property of "ItemsControl"…

感谢......

推荐答案

您可以收集的意见进行排序，而该分类集合本身：

You can sort the view of the collection rather that sorting the collection itself:

// xmlns:scm="clr-namespace:System.ComponentModel;assembly=WindowsBase"
<myView.Resources>
    <CollectionViewSource x:Key="ItemListViewSource" Source="{Binding Itemlist}">
        <CollectionViewSource.SortDescriptions>
            <scm:SortDescription PropertyName="SortingProperty" />
        </CollectionViewSource.SortDescriptions>
    </CollectionViewSource>
</myView.Resources>

然后就可以使用CollectionViewSource作为ItemSource：

And then you can use the CollectionViewSource as ItemSource:

ItemsSource="{Binding Source={StaticResource ItemListViewSource}}"
