Question

我有一个像这样定义的xaml：

<Grid>
   <Rectangle Grid.Column="0" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="1" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="2" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="3" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="4" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="5" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="6" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="7" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="8" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="9" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="10" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="11" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
</Grid>

我找不到的是一种访问网格列号I的方法，我试图投射矩形，但我找不到它的适当属性。

Answer 1

如果您有Rectangle个对象，则可以使用 GetValue() 方法获取该对象。假设rect是对象名称，那么你可以这样得到它：

int column = (int)rect.GetValue(Grid.ColumnProperty);

Grid.Column是附加属性，而不是Rectangle的正常依赖属性。因此，你必须在那里传递Grid.ColumnProperty。

Answer 2

Grid.Column是attached property，因此定义了静态getter和setter方法Grid.GetColumn和Grid.SetColumn。请特别注意链接的MSDN文章的Attached Properties in Code部分。

在代码中获取Grid.Column属性值的常用方法是调用静态getter方法：

int column = Grid.GetColumn(rect);

获取矩形的grid.column
