改变userControl的可见性
本文关键字:可见性 userControl 改变 | 更新日期: 2023-09-27 17:54:44
我得到了一个带有按钮的userControl
<Button Content="Button" x:Name="button"/>
后面代码中的public Button button { get; set; }
我在另一个页面中使用这个userControl
CrudPage
<UC:MyUC x:Name="objectForm" />
是否可以修改这个按钮的可见性从CrudPage的代码背后?
Create DenedencyProperty
in UserControl
:
public static DependencyProperty ButtonVisibilityProperty = DependencyProperty.Register("ButtonVisibility", typeof(Visibility), typeof(MyUserControl), null);
public Visibility ButtonVisibility
{
get { return (Visibility)GetValue(ButtonVisibilityProperty); }
set { SetValue(ButtonVisibilityProperty, value); }
}
绑定Button.Visibility
:
<Button
Visibility="{Binding ElementName=userControl, Path=ButtonVisibility}"
Content="Button"
x:Name="button"/>
假设UserControl
有x:Name="userControl"
<UserControl ... x:Name="userControl">
你应该能够从外部控制Button
的Visibility
,像这样:
<local:MyUserControl ButtonVisibility="Collapsed"/>
