我是WPF的新手,我无法解决这个问题,希望你们可以帮忙解决这个问题。问题是DesignerItemTemplate
在项目控件中不起作用,我试着直接将它用于我可以拖动它的一个项目。如果代码看起来很乱,请原谅我。提前致谢

而不是
Template="{Binding Mode=OneWay, Source={StaticResource DesignerItemTemplate}}" />试试这个:
Template="{StaticResource DesignerItemTemplate}" />
如果这没有帮助,请你提供一个更简单的例子来说明问题并描述你想要实现的目标。我不清楚你想要达成什么目标。

我发现了问题!它是继承到可观察对象的InspectionItemList集合对象。当我删除对象中的obeservable时它完美无缺。谢谢Clemens和Stackoverflow这个网站真的对我很有帮助。
