我先谈一个问题,希望有人能帮助我解决问题。 我现在举一个例子,即我的节点含有一套儿童节点,其可见度是伪造的。 我希望,如果所有养育孩子的人都看不见,我就能够消除树苗中的 to。 这是可能的吗? 例如:
<TreeView Margin="10,10,0,13" Name="TreeView1" HorizontalAlignment="Left" VerticalAlignment="Top" Width="194" Height="200">
<TreeViewItem Header="Cold Drinks">
<TreeViewItem Header="Coke" Visibility="False"></TreeViewItem>
<TreeViewItem Header="Pepsi" Visibility="False"></TreeViewItem>
</TreeViewItem>
</TreeView>
怎样才能使冷的 Drink树听起来掩盖 to的arrow子?
如果你看到树苗的衰败控制,你就会看到,托格林纽特的可见度受项目管制。 HasItems. 象这样的三叉 -:
<Trigger Property="ItemsControl.HasItems">
<Setter TargetName="Expander" Property="UIElement.Visibility" Value="{x:Static Visibility.Hidden}" />
<Trigger.Value>
<s:Boolean>False</s:Boolean>
</Trigger.Value>
</Trigger>
因此,作为一个工作领域,你可以自行建立由塔夫姆特制衍生的习俗控制,并将贵岛财产与你本人的财产相挂钩,这些财产将穿过你的所有子女情况(TreeViewItems),如果所有物品都藏匿/col落,则将归还真实情况。 这样,你的洞.将自动隐藏在Trigger。
如果你想要知道如何建立习俗控制,并把它与你的《刑法》财产联系起来,你可以提到这一点:
This is somewhat same what you has been looking for. Hope this helps..
内部(即关键航道)和违约模板都以<>HasItems为根据,了解是否有子女。 你们很可能需要把树木的产物列入清单,并过滤已经崩溃的物品。
