我有用户控件,该控件定义了Telerik控件RadTreeViewItem
的自定义样式。问题是,当我没有x:key时没有任何错误,但是当我添加x:key属性时却出现了错误“ The resource "RadTreeViewItemStyle" could not be resolved.
”
<ResourceDictionary>
<Style x:Key="MySuperGoodStyle" TargetType="telerik:RadTreeViewItem" BasedOn="{StaticResource RadTreeViewItemStyle}">
<Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" />
<Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}" />
</Style>
</ResourceDictionary>
在运行时没有任何问题,该样式按预期工作正常,因此看起来像是仅设计错误。

尝试在此之前添加:
<Style TargetType="telerik:RadTreeViewItem" x:Key="RadTreeViewItemStyle">
<Setter Property="FocusVisualStyle" Value="{StaticResource TreeviewFocusVisual}"/>
<Setter Property="HorizontalContentAlignment" Value="Left"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Padding" Value="1 4 5 4"/>
<Setter Property="MinHeight" Value="24"/>
<Setter Property="IsDropAllowed" Value="True"/>
<Setter Property="IsEnabled" Value="True"/>
<Setter Property="IsTabStop" Value="False"/>
<Setter Property="telerik:DragDropManager.TouchDragTrigger" Value="TapAndHold"/>
<Setter Property="KeyboardNavigation.TabNavigation" Value="Local"/>
<Setter Property="Template" Value="{StaticResource TreeViewItemDefaultTemplate}"/>
<Setter Property="ItemsPanel">
<Setter.Value>
<ItemsPanelTemplate>
<telerik:TreeViewPanel VerticalAlignment="Bottom"/>
</ItemsPanelTemplate>
</Setter.Value>
</Setter>
</Style>
并确保标题中包含>
