Question

我想在C＃中实例化整个XAML Grid对象。我的网格对象是一个野兽，它具有9个用户输入字段，边框，标签和图像。

我还希望有Grid对象的五个实例，我想在运行时动态地实例化它们（按下按钮）。这可能吗？最好的方法是什么？这是我的Grid对象...

                    </Grid>

Answer 1

用代码简单地新建一个网格

Grid grid = new Grid() { Margin = new Thickness(2) };

并向其中添加元素。

grid.Children.Add(new Border());
TextBlock t = new TextBlock();
t.SetValue(Grid.RowProperty, 0);
t.SetValue(Grid.ColumnProperty, 2);
grid.Children.Add(t);
//etc...

或者您可以将UserControl项目添加到项目中，然后将Grid放入其xaml中。然后，您可以根据需要更新尽可能多的MyGridControl。

Answer 2

您可以执行以下操作：

创建一个包含网格的UserControl，例如MyBeastGrid
在目标表单中有一个占位符，应在其中放置那些实例化的网格，例如MyPlaceholder
添加按钮（或应将{{1}}添加到MyBeastGrid的其他触发机制）
在按钮的MyPlaceholder事件处理程序中，您只需调用Click

如果您需要将一些参数传递给MyPlaceholder.Children.Add(new MyBeastGrid());，请在其中定义一些公共属性，然后提供参数化的构造函数或使用MyBeastGrid调用网格

我建议您使用new MyBeastGrid() { Property1 = value1, Property2 = value2 };存储ScrollViewer实例，因为它可以滚动显示。

如何在C＃中实例化整个XAML网格对象？
