如何解决Silverlight-包含ListBox和包含StackPanel Alignment的ListBox的网格
|| 我有2行4列的网格 第一行包含标题 第二行包含水平折叠的ListBox内容，其中listBoxItems是具有4个列项目（4个textBlocks）的水平方向的StackPanels，我希望这些列具有与Grid Columns相同的宽度 我该怎么做？非常感谢您的帮助！！！ 这就是我现在所拥有的<UserControl

解决方法
我猜您可以做的是将textBlocks的宽度绑定到已在一列中拉伸的某种“不可见”网格的实际宽度。
像这样的东西（未尝试的代码...）：
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=\"*\"/>
<ColumnDefinition Width=\"*\"/>
<ColumnDefinition Width=\"*\"/>
<ColumnDefinition Width=\"*\"/>
</Grid.ColumnDefinitions>
<Grid x:Name=\"invisibleGrid\" />
</Grid>
<TextBlock x:Name=\"textBlockColumn1\" Width=\"{Binding ActualWidth,ElementName=invisibleGrid}\"/>
public class ActualSizePropertyProxy : FrameworkElement,INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
public FrameworkElement Element
{
get { return (FrameworkElement)GetValue(ElementProperty); }
set { SetValue(ElementProperty,value); }
}
public double ActualHeightValue
{
get { return Element == null ? 0 : Element.ActualHeight; }
}
public double ActualWidthValue
{
get { return Element == null ? 0 : Element.ActualWidth; }
}
public static readonly DependencyProperty ElementProperty =
DependencyProperty.Register(\"Element\",typeof(FrameworkElement),typeof(ActualSizePropertyProxy),new PropertyMetadata(null,OnElementPropertyChanged));
private static void OnElementPropertyChanged(DependencyObject d,DependencyPropertyChangedEventArgs e)
{
((ActualSizePropertyProxy)d).OnElementChanged(e);
}
private void OnElementChanged(DependencyPropertyChangedEventArgs e)
{
FrameworkElement oldElement = (FrameworkElement)e.OldValue;
FrameworkElement newElement = (FrameworkElement)e.NewValue;
newElement.SizeChanged += new SizeChangedEventHandler(Element_SizeChanged);
if (oldElement != null)
{
oldElement.SizeChanged -= new SizeChangedEventHandler(Element_SizeChanged);
}
NotifyPropChange();
}
private void Element_SizeChanged(object sender,SizeChangedEventArgs e)
{
NotifyPropChange();
}
private void NotifyPropChange()
{
if (PropertyChanged != null)
{
PropertyChanged(this,new PropertyChangedEventArgs(\"ActualWidthValue\"));
PropertyChanged(this,new PropertyChangedEventArgs(\"ActualHeightValue\"));
}
}
}
