我有一个停靠在停靠面板右侧的选项卡控件。选项卡控件的宽度设置为 10，不透明度设置为 0。当我将鼠标移到它上面时，我希望选项卡控件的宽度更改为 200，不透明度更改为 100。然后，当我将鼠标移开时，让选项卡控件返回其原始值。我不知道该怎么做。有人可以帮忙吗？下面是我的标记，我试图让选项卡控件首先显示。

我使用 ItemTemplate 设置了我的 Combobox 并成功填充了它。但是，当我在 ComboBox 中选择一个项目时，会显示 Data.MaterialNumber 而不是我选择的实际文本。
MaterialNumbers 是一个 ObservableCollection<>
有人能告诉我为什么我的 ComboBox 在选择后没有正确显示该项目吗？
// Binding from my ViewModel, which retrieves material numbers correctly.
ObservableCollection<MaterialNumber> MaterialNumbers = GetMaterialNumbers();
