DataGrid控件所使用的数据源也是一个集合类。通常使用ObservableCollection泛型类。而不使用List泛型类。因为ObservableCollection类内部自带通知功能。

使用DataGrid控件绑定的时候，通常可以构建一个类，代码如下：

public class GridData
{
    public string Name { get; set; }
    public int Age { get; set; }
    public bool Male { get; set; }
    public static ObservableCollection<GridData> GetData()
    {
        ObservableCollection<GridData> data = new ObservableCollection<GridData>();
        data.Add(new GridData()
        {
            Name = "John Doe",
            Age = 30,
            Male = true
        });
        data.Add(new GridData()
        {
            Name = "Jane Doe",
            Age = 32,
            Male = false
        });
        data.Add(new GridData()
        {
            Name = "Jason Smith",
            Age = 54,
            Male = true
        });
        data.Add(new GridData()
        {
            Name = "Kayli Jayne",
            Age = 25,
            Male = false
        });
        return data;
    }
}

绑定语句：

this.dataGrid1.ItemsSource = GridData.GetData();

对于dataGrid，有两种方式生成列，一直是自动生成，一种是手动生成。代码如下：

<sdk:DataGrid AutoGenerateColumns="True" Height="140" HorizontalAlignment="Left" Margin="34,27,0,0" Name="dataGrid1" VerticalAlignment="Top" ;247" />

<sdk:DataGrid AutoGenerateColumns="False" Height="140" HorizontalAlignment="Left" Margin="34,247,0,0" Name="dataGrid2" VerticalAlignment="Top" ;247">
           <sdk:DataGrid.Columns>
               <sdk:DataGridTextColumn CanUserReorder="True" CanUserResize="True" CanUserSort="True" ;Auto" Binding="{Binding Name}" Foreground="#FFE27474" Header="Name" IsReadOnly="True" />
               <sdk:DataGridTextColumn CanUserReorder="True" CanUserResize="True" CanUserSort="True" ;Auto" Binding="{Binding Age}" Header="Age" IsReadOnly="True" />
               <sdk:DataGridTextColumn CanUserReorder="True" CanUserResize="True" CanUserSort="True" ;Auto" Binding="{Binding Male}" Header="Male" IsReadOnly="True" />
           </sdk:DataGrid.Columns>
       </sdk:DataGrid>
