得到一个矩形

Question

我有一个XAML定义像这样的grid.colum：

<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> 

我没有找到一种方法来访问我，已经尽力施展矩形网格列数，但我没有找到它的适当属性。

Answer 1

如果您有Rectangle对象，您可以使用GetValue()方法得到它。说rect的对象名称，然后你可以这样说：

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

Grid.Column的附加属性和矩形的不正常的依赖项属性。因此你必须在那里通过Grid.ColumnProperty。

Answer 2

Grid.Column是attached property，因此定义了静态吸气器和设定器方法Grid.GetColumn和Grid.SetColumn。请特别注意链接的MSDN文章的Attached Properties in Code部分。

通常的方式来获得在代码中Grid.Column属性的值是调用静态getter方法：

int column = Grid.GetColumn(rect);
