Wpf 如何使用按钮填充ItemsControl
我需要用可点击按钮的单元格填充面板,如下所示: 这已在矩形中完成:Wpf 如何使用按钮填充ItemsControl,wpf,xaml,user-interface,itemscontrol,Wpf,Xaml,User Interface,Itemscontrol,我需要用可点击按钮的单元格填充面板,如下所示: 这已在矩形中完成: <ItemsControl ItemsSource="{Binding Path=Cells}"> <ItemsControl.ItemTemplate> <DataTemplate> <Rectangle> <Rectangle.Fill>
<ItemsControl ItemsSource="{Binding Path=Cells}">

<commonControls:UniformGrid ElementsGap="5" HorizontalCount="{Binding Path=CellsInRow}" />

但我需要用按钮来做。我正在尝试:
<ItemsControl ItemsSource="{Binding Path=Cells}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button>
<Button.Background>
<SolidColorBrush Color="Red"></SolidColorBrush>
</Button.Background>
</Button>
</DataTemplate>
</ItemsControl.ItemTemplate>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<commonControls:UniformGrid ElementsGap="5" HorizontalCount="{Binding Path=CellsInRow}" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
但似乎是这样的:
如何使用按钮从第一张图像中提取单元格?
UniformGrid的代码如下:
public class UniformGrid : Panel
{
public static readonly DependencyProperty HorizontalCountProperty =
DependencyProperty.Register("HorizontalCount", typeof (int), typeof (UniformGrid),
new PropertyMetadata(default(int)));
public int HorizontalCount
{
get { return (int) GetValue(HorizontalCountProperty); }
set { SetValue(HorizontalCountProperty, value); }
}
public static readonly DependencyProperty ElementsGapProperty =
DependencyProperty.Register("ElementsGap", typeof (double), typeof (UniformGrid),
new PropertyMetadata(default(double)));
public double ElementsGap
{
get { return (double) GetValue(ElementsGapProperty); }
set { SetValue(ElementsGapProperty, value); }
}
protected override Size MeasureOverride(Size availableSize)
{
return new Size();
}
protected override Size ArrangeOverride(Size finalSize)
{
if (Children != null && Children.Count != 0)
{
var squareSideForElement = (finalSize.Width - (HorizontalCount - 1)*ElementsGap)/HorizontalCount;
var sizeOfElement = new Size(squareSideForElement, squareSideForElement);
for (var i = 0; i < Children.Count; i++)
{
var rowIndex = i%HorizontalCount;
var columnIndex = i/HorizontalCount;
var resultPoint = new Point
{
X = rowIndex*(squareSideForElement + ElementsGap),
Y = columnIndex*(squareSideForElement + ElementsGap)
};
Children[i].Arrange(new Rect(resultPoint, sizeOfElement));
}
}
return finalSize;
}
}

受保护的覆盖尺寸测量覆盖(尺寸可用尺寸)
{
返回新的大小();
}
受保护的替代尺寸排列替代(尺寸最终化)
{
if(Children!=null&&Children.Count!=0)
{
var squareSideForElement=(finalSize.Width-(HorizontalCount-1)*ElementsGap)/HorizontalCount;
var sizeOfElement=新尺寸(squareSideForElement,squareSideForElement);
for(var i=0;i
您的度量值必须调用每个孩子。请阅读中的备注部分,特别是以下注释:
在此过程中,元素应在每个子元素上调用Measure,
否则子元素的大小或排列将不正确
您至少应该这样做:
protected override Size MeasureOverride(Size availableSize)
{
foreach (UIElement element in InternalChildren)
{
element.Measure(availableSize);
}
return new Size();
}
如果要确保每个子对象都计算其最大首选大小,可以传递无限宽和无限高以进行测量:
protected override Size MeasureOverride(Size availableSize)
{
availableSize = new Size(double.PositiveInfinity, double.PositiveInfinity);
foreach (UIElement element in InternalChildren)
{
element.Measure(availableSize);
}
return new Size();
}
你知道WPF里已经有一个了吗?谢谢你,克莱门斯!但现在看来是这样的:。矩形(正方形)怎么样?不知道。计算布局的是您的代码。你也许应该在你的数据模板中设置按钮的宽度和高度。是的!我用电脑处理它。谢谢大家的关注!
