我已经创建了一个XAML对话框窗口。在大多数情况下，我需要动态填充此窗口，这是我以前从未尝试解决的问题，而且我无法在此网站或MSDN上找到任何内容。这是我在.xaml：
<GroupBox Header="Pipe Segments" Height="Auto" Margin="5,0,0,0">
<StackPanel Orientation="Vertical">
<StackPanel x:Name="PipeSegRow1" Orientation="Horizontal" Margin="0,5,0,0">

<StackPanel x:Name="PipeSegR5C6" Orientation="Vertical" Margin="5,0,0,0" Width="90"></StackPanel>
</StackPanel>
</StackPanel>
</GroupBox>
窗口中还有更多的人。我想要实现的目标是：从Checkbox的内容动态地在StackPanel行和列中放置新的List<T>。这就是我尝试的内容，但我不确定它是否会起作用，或者我是否以正确的方式来到这里。我想提前指出，List<T>最初使用的GroupBox不是上面的public void PopulateWindow()
{
int itr = 1; //TO SCROLL THROUGH THE ROWS AND COLUMNS
var fecPipes = new FilteredElementCollectoR(m_pDoc); //GET ALL PIPES
var lstRVTPipes = fecPipes.OfCategory(BuiltInCategory.OST_PipeCurves).
OfClass(typeof(PipeType)); //FILTER RVT PIPES
var lstMEPSizes = fecPipes.OfCategory(BuiltInCategory.OST_PipeCurves).
OfClass(typeof(MEPSize)); //FILTER NOMINAL DIAMETERS
var lstPipeSeg = fecPipes.OfCategory(BuiltInCategory.OST_PipeCurves).
OfClass(typeof(PipeSegment)); //FILTER PIPE SEGMENTS
foreach (PipeType pPipe in lstRVTPipes)
{
CheckBox cb = new CheckBox(); //CREATE NEW CHECK BOX
cb.Height = 15; //SET CHECK BOX HEIGHT
cb.Name = pPipe.FamilyName.ToString(); //SET THE NAME OF THE CHECK BOX
cb.Content = pPipe.FamilyName.ToString(); //SET THE CONTENT DISPLAY OF THE CHECK BOX
switch (itr) //PLACE THE CHECK BOX
{
case 1:
cb.BindingGroup = RVTPipeR1C1.BindingGroup; //DOES THIS WORK?
RVTPipeR1C1.DataContext = cb; //DOES THIS WORK?
/* I'D LIKE TO DO SOMETHING LIKE:
* RVTPipeR1C1.Add(cb); OR
* cb.Location = RVTPipeR1C1.Location;
* BUT THAT'S NOT A OPTION... :-( */
break;
// THEN IT KEEPS GOING LIKE THIS FOR A WHILE...
//
//
}
itr++;
}
}
。抱歉让人感到困惑 - 只要知道他们基本上是一样的。
*fd = pipe_fds[0];
如果有人可以告诉我如何放置这些物品，或者我做了对错的话，我会非常感激！任何有用的东西的链接都很棒！谢谢！

要动态放置元素集合，您可以使用ItemsControl。您可以在此处阅读：https://msdn.microsoft.com/ru-ru/library/system.windows.controls.itemscontrol(v=vs.110).aspx，https://professorweb.ru/my/WPF/binding_and_styles_WPF/level20/20_2.php以及使用它的简单示例：http://www.wpf-tutorial.com/list-controls/itemscontrol/。
在代码中，您为元素创建ObservableCollection<T>，其中T为ViewModel CheckBox
对于ItemsControl，您必须将StackPanel设为ItemsControl.ItemsPanel，ItemsSource="{Binding Path=Elements}"（其中Elements是您的ObservableCollection<T>）和{{1}为您的ItemsControl.ItemTemplate添加DataTemplate
我希望，我的建议会对你有所帮助）

您可以通过将UIElement添加到StackPanel的Children属性来将其添加到StackPanel：
PipeSegR1C1.Children.Add(cb);
StackPanel没有行和列的概念。它只是将子元素排列成一条水平或垂直方向的线条，具体取决于Orientation属性的值：https://msdn.microsoft.com/en-us/library/system.windows.controls.stackpanel(v=vs.110).aspx
如果要在由列和行组成的灵活网格区域中组织控件，可以使用Grid元素并向其添加ColumnDefinition和RowDefinitions。有关详细信息，请参阅MSDN：https://msdn.microsoft.com/en-us/library/system.windows.controls.grid(v=vs.110).aspx#Properties
