想从铯文件网格绑定列表在XAML与任何code $ c中$ C背后 [英] want to bind List from Cs file to Grid in Xaml with out any code in code behind

问题描述

我想结合我的DataGrid这是在XAML文件在收集这是不是在code落后，但在CS文件

我尝试了不同的方法，但没有成功，其实我不想写任何code。在隐藏文件code。

类code

 公共类员工：INotifyPropertyChanged的
{
    私人诠释_id;
    私人字符串_FirstName;
    私人字符串_LastName;
    私人双人_Salary;
    公共事件PropertyChangedEventHandler的PropertyChanged;

    公务员（）
    {
    }
    公务员（INT PID，串pFirstName，串pLastName，双pSalary）
    {
        n = PID;
        名字= pFirstName;
        姓氏= pLastName;
        工资= pSalary;
    }

    公众诠释标识
    {
        组
        {
            _id =价值;
            NotifyPropertyChanged（ID）;
        }
        {返回_id; }
    }
    公共字符串名字
    {
        组
        {
            _FirstName =价值;
            NotifyPropertyChanged（名字）;
        }
        {返回_FirstName; }
    }
    公共字符串名字
    {
        组
        {
            _LastName =价值;
            NotifyPropertyChanged（名字）;
        }
        {返回_LastName; }
    }
    公共双薪
    {
        组
        {
            _Salary =价值;
            NotifyPropertyChanged（工资）;
        }
        {返回_Salary; }
    }
    私人无效NotifyPropertyChanged（字符串pProperty）
    {
        如果（的PropertyChanged！= NULL）
            的PropertyChanged（这一点，新PropertyChangedEventArgs（pProperty））;
    }
}


公共类EmployeeCollection
{
     的ObservableCollection＆LT;员工＆GT; lstEmp =新的ObservableCollection＆LT;员工＆GT;（）;
     公众的ObservableCollection＆LT;员工＆GT;装getEmployees（）
     {
          lstEmp.Add（新员工（1，名字1，姓氏1，1.1））;
          lstEmp.Add（新员工（2，名字2，姓氏2，2.2））;
          lstEmp.Add（新员工（3，名字3，姓氏3，3.3））;
          lstEmp.Add（新员工（4，名字4，姓氏4，4.4））;
          lstEmp.Add（新员工（5，名字5，姓氏5，5.5））;
          lstEmp.Add（新员工（6，名字6，姓氏6，6.6））;

          返回lstEmp;
     }
}
 

它的XAML code

 ＆LT;我：数据网格的AutoGenerateColumns =真正的保证金=20,0,68,10NAME =dataGrid2高度=135​​VerticalAlignment =底部/＆GT ;
 

解决方案

如果我能修改类的方式，对我来说很有意义，我会改变装getEmployees（）以静态属性。然后，你可以简单的写（本地是一个命名空间preFIX包含命名空间员工）：

 ＆LT;数据网格的ItemsSource ={X：静态地方：Employee.Employees}/＆GT;
 

如果你想保持这个类事情是这样的，首先声明一个的ObjectDataProvider 作为资源（例如，在＆LT; Window.Resources＆GT; ）：

 ＆LT; ObjectDataProvider的对象类型=本地：雇员方法名=装getEmployees
    X：关键=员工/＆GT;
 

，然后使用：

 ＆LT;数据网格的ItemsSource ={绑定源= {的StaticResource员工}}/＆GT;
 

I want to bind my DataGrid which is in Xaml file with collection which is not in the Code behind but in a cs file

I tried different methods but no success, Actually I do not want to write any code in Code behind file.

class Code

public class Employee : INotifyPropertyChanged
{            
    private int _Id;
    private string _FirstName;
    private string _LastName;
    private double _Salary;
    public event PropertyChangedEventHandler PropertyChanged;

    public Employee()
    {
    }
    public Employee(int pId, string pFirstName, string pLastName, double pSalary)
    {
        Id = pId;
        FirstName = pFirstName;
        LastName = pLastName;
        Salary = pSalary;
    }

    public int Id
    {
        set 
        { 
            _Id = value;
            NotifyPropertyChanged("Id");
        }
        get { return _Id; }
    }
    public string FirstName
    {
        set 
        { 
            _FirstName = value;
            NotifyPropertyChanged("FirstName");
        }
        get { return _FirstName; }
    }
    public string LastName
    {
        set 
        { 
            _LastName = value;
            NotifyPropertyChanged("LastName");
        }
        get { return _LastName; }
    }
    public double Salary
    {
        set 
        {             
            _Salary = value;
            NotifyPropertyChanged("Salary");
        }
        get { return _Salary; }
    }
    private void NotifyPropertyChanged(string pProperty)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(pProperty)); 
    }
}


public class EmployeeCollection
{
     ObservableCollection<Employee> lstEmp = new ObservableCollection<Employee>();
     public ObservableCollection<Employee> GetEmployees()
     {
          lstEmp.Add(new Employee(1,"Firstname 1", "Lastname 1", 1.1 ));
          lstEmp.Add(new Employee(2, "Firstname 2", "Lastname 2", 2.2));
          lstEmp.Add(new Employee(3, "Firstname 3", "Lastname 3", 3.3));
          lstEmp.Add(new Employee(4, "Firstname 4", "Lastname 4", 4.4));
          lstEmp.Add(new Employee(5, "Firstname 5", "Lastname 5", 5.5));
          lstEmp.Add(new Employee(6, "Firstname 6", "Lastname 6", 6.6));

          return lstEmp;
     }
}

its Xaml code

<my:DataGrid  AutoGenerateColumns="true" Margin="20,0,68,10" Name="dataGrid2" Height="135" VerticalAlignment="Bottom" />

解决方案

If I could modify the class in a way that makes sense to me, I would change GetEmployees() to a static property. You could then simply write (local is a namespace prefix for the namespace containing Employee):

<DataGrid ItemsSource="{x:Static local:Employee.Employees}" />

If you want to keep the class the way it is, first declare a ObjectDataProvider as a resource (e.g. in <Window.Resources>):

<ObjectDataProvider ObjectType="local:Employee" MethodName="GetEmployees"
    x:Key="employees" />

And then use that:

<DataGrid ItemsSource="{Binding Source={StaticResource employees}}" />
