嵌套控件结构 - 在 XAML 还是 C# 中? [英] Nested controls structure - in XAML or C#?

问题描述

我想创建一个由相当多的元素组成的结构，它的基本布局是这样的:

I want to create a structure which consists of quite some elements, the basic layout of it goes like that:

<UniformGrid>
  <Border>        // This one is 9x
    <UniformGrid> // This one is 9x, each as a child of the border
      <Border>    // This one is again 9x, so at total 9x9 = 81 of these
        <TextBox> // Same as above, each one as a child of the Border
        .....
        </TextBox>
      </Border>
    </UniformGrid>
</UniformGrid>

所以，有这么多控件，我想知道什么解决方案更优雅、更合适:

So, having that many number of controls, I was wondering what solution is more elegant and proper:

所以整个设计都是用XAML完成的，写的有点多，所有的控件都是手动设置的

So the whole design is done in XAML, which is quite some writing, and all the controls are manually setup there

所以只有主要的 UniformGrid 和 9 个较小的 Uniform 网格是使用 XAML 创建的，然后所有其他东西都是动态创建的，用 C# 编写.另外，如果这是选择，那么请告诉我如何从代码端向边框添加子项的方法.至于现在，这是我的主要方式，我想出了这个:

So just the main UniformGrid and the 9 smaller Uniform grids are created using XAML, then all the other stuff is created dynamically, written in C#. Also if this would be the choice, then please show me the way how to add a child to a border from the code side. As for now, this was my main way of going and I came up with that:

    private void InitializeCells()
    {
        for (int i = 1; i <= 9; i++)
        {
            object foundControl = sudokuGrid.FindName("cellBorder" + i.ToString());
            Border foundGridControl = (Border)foundControl;
            for (int j = 1; j <= 9; j++)
            {
                TextBox cell = new TextBox();
                cell.MaxLength = 1;
                cell.FontSize = 30;
                cell.Name = "cell" + j.ToString();
                cell.VerticalContentAlignment = VerticalAlignment.Center;
                cell.HorizontalContentAlignment = HorizontalAlignment.Center;
                // HOW TO ADD CHILDREN????
            }
        }
    }
    private void InitializeCellBorders()
    {
        for (int i = 1; i <= 9; i++)
        {
            object foundControl = sudokuGrid.FindName("block" + i.ToString());
            UniformGrid foundGridControl = (UniformGrid)foundControl;
            for (int j = 1; j <= 9; j++)
            {
                Border cellBorder = new Border();
                cellBorder.Name = "cellBorder" + j.ToString();
                cellBorder.BorderBrush = Brushes.DodgerBlue;
                foundGridControl.Children.Add(cellBorder);
            }
        }
    }

3:混合

某种不同的 C# 和 XAML 代码的混合，我还没有想出:)

3: Mixture

Some kind of different mixture of C# and XAML code, which I havent come up with yet :).

推荐答案

都没有.使用 ItemsControl 或它的派生之一:

None of them. Use an ItemsControl or one of it's derivatives:

<ItemsControl ItemsSource="{Binding SomeCollectionOfViewModel}">
   <ItemsControl.ItemsPanel>
      <ItemsPanelTemplate>
         <UniformGrid/>
      </ItemsPanelTemplate>
   </ItemsControl.ItemsPanel>
   <ItemsControl.ItemTemplate>
       <DataTemplate>
          <ItemsControl ItemsSource="{Binding SomeCollection}">   <!-- Nested Content -->
              ...
       </DataTemplate>
   <ItemsControl.ItemTemplate>
</ItemsControl>
