c# - 如何以编程方式在 C# WPF 中创建 DataGrid？

Question

如何在 C# WPF 中以编程方式创建 DataGrid？我可以生成多个包含信息的 DataGrids - 取决于用户选择的内容

例如:

if(true)
{
  // Create a DataGrid programatically
  DataGrid DG = new DataGrid();
  DG.ColumnHeader 1 = "Name"
  DG.ColumnHeader 2 = "Age"

  // Load info to the datagrid from somewhere
  // Add under Name column the name "Fred" and "Tom"
  // Add under Age column "26" and "18"
  DG.FieldNameColumn.Row1 = "Fred"
  DG.Age.Row1 = "26"
  DG.FieldNameColumn.Row2 = "Tom"
  DG.Age.Row2 = " 18"
}
else
{
  // dont generate a DG ( don't do anything here)
}

您熟悉 MVVM 吗？我建议以“正确”的方式进行操作，并创建一个关联的 ViewModel 来保存项目集合。 DataGrid 将绑定(bind)到该项目集合。

不过，要回答您的问题，您可以通过以下方式完成您想要的:

  private void Button_Click(object sender, RoutedEventArgs e)
    {
        var nameBinding = new Binding("Name")
        {
            Mode = BindingMode.Default,
            UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged
        };

        var ageBinding = new Binding("Age")
        {
            Mode = BindingMode.Default,
            UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged
        };

        var dataGrid = new DataGrid();
        dataGrid.Columns.Add(new DataGridTextColumn
        {
            Header = "Name",
            Binding = nameBinding
        });
        dataGrid.Columns.Add(new DataGridTextColumn
        {
            Header = "Age",
            Binding = ageBinding
        });
        dataGrid.ItemsSource = new ObservableCollection<Info>
        {
            new Info
            {
                Name = "Name 1",
                Age = "100"
            }
        };

        MainGrid.Children.Add(dataGrid);
    }

    public class Info
    {
        public string Name { get; set; }
        public string Age { get; set; }
    }

注意 MainGrid 是您要将 DataGrid 添加到的容器的名称。
