推荐答案

以下是示例代码

在行"Data"中定义要嵌入的数据

Here is the sample code

Data to be embedded in a row is defined in the class ''Data''

public class Data
{
    public string Name { get; set; }
}

XAML前端代码将为:

XAML front end code will be:

<UserControl .... xmlns:my="clr-namespace:System.Windows.Controls; assembly=System.Windows.Controls.Data>...
<my:DataGrid x:Name="dg" AutoGenerateColumns="True"></my:DataGrid>
<TextBox x:Name="Nametxt" />
<Button Content="Add" Click="Btn_click"/>

C#背后的代码是

Code behind C# is

List<data> source = new List<data>();
dg.ItemsSource = source;

void Btn_Click(...)
{
        source.Add(new Data()
        { 
            Name = Nametxt.Text.Trim();
        });
}</data></data>
