为 Xamarin 创建一个 ControlTemplate 而不使用 XAML

Question

在不使用 XAML 的情况下，是否有人有为元素创建 ControlTemplate 的示例？

例子：

<ControlTemplate>
      <Grid>
           <//Inner grid elements>
      </Grid>
</ControlTemplate>

      
  to C# code
      

var grid = new Grid();

//This isnt how you do it Im stuck here 

var ControlTemplate = new ControlTemplate(grid)

你可以参考下面的代码。

 public class Page1 : ContentPage
{
    public Page1()
    {
        ControlTemplate controlTemplate = new ControlTemplate(typeof(Grid1));
        ControlTemplate = controlTemplate;
    }
}
public class Grid1 : ContentView
{
    public Grid1()
    {
        Grid grid = new Grid()
        {
            VerticalOptions = LayoutOptions.FillAndExpand,
            HorizontalOptions = LayoutOptions.FillAndExpand,
            RowDefinitions =
            {
                new RowDefinition{Height =GridLength.Auto},
                new RowDefinition{Height =GridLength.Auto},
            },
            ColumnDefinitions =
            {
                new ColumnDefinition{ Width= GridLength.Auto},
                new ColumnDefinition{ Width= GridLength.Auto},

            },

        };
        grid.Children.Add(new Label
        {
            Text = "column0,row0",
        }, 0, 0);

        grid.Children.Add(new Label
        {
            Text = "column1,row1"
        }, 1, 1);

        Content = grid;
    }
}
