我以编程方式将tabitems添加到tabcontrol。我有一个自定义tabItem，标题中有两个按钮，一个用于关闭选项卡，另一个用于执行其他功能（它触发升序或降序排序）。关闭按钮的内容是一个常量，另一个按钮的内容根据选项卡的datacontext中的布尔值而改变。只有选定选项卡中的按钮显示在选项卡标题中。
最初，两个按钮都会显示在最后创建的标签上。我遇到的问题是，当我选择标签时，新选择的标签上的关闭按钮的内容将应该是可见的，但是绑定按钮的内容已经消失（按钮在那里）。
我应该指出问题按钮的内容是两个多边形之一，具体取决于绑定源的值。
我还应该指出，如果我点击空白按钮，标签页上会出现相应的图像。
添加更多混淆是附加到按钮的tooltip属性行为正确 - 它根据绑定源显示相应的工具提示文本。
自定义TabItem主要是从我包含的ResourceDictionary创建的。
请帮助，我承认我的wpf知识有限。

答案 0 :(得分：0)
我解决了自己的问题。在我尝试解决这个问题时，我选择了一个togglebutton和一个图像，而不是常规按钮和多边形。然后我意识到我错过了tabitem的选择状态的触发条件。对于任何感兴趣的人，最终解决方案都包括在内。顺便说一下，创建一个从tabitem继承的控件的想法和大多数样式来自这个站点：http://www.c-sharpcorner.com/uploadfile/dpatra/closable-tab-control-in-wpf/。
最后，对于那些冒昧的人来说，这个问题与MVVM无关。
