我正試圖使用Canvas
佈局將項目列表綁定到ItemsControl
,其中項目具有多個「級別」。這是最簡單的使用圖像來解釋:在畫布上的DataBound項目中設置Z索引
我的較低水平是下拉陰影在這種情況下。因爲我認爲陰影會附加到主要元素(a Button
),所以我創建了另一個視覺元素,一個邊框,它位於Button的後面並附有陰影。我想要的是我的所有影子元素都處於相同的整體ZIndex
,並且所有的Button元素都在它們之上。
在實踐中,似乎WPF渲染我的模板的內容作爲一個單一的UI元素,基本上是扁平化在其中的ZIndex
ES。有沒有什麼辦法可以讓ZIndex
的值不會變平?
我創建了一個樣本下面這說明問題:

提前爲你能提供任何想法謝謝!
這是結束我會來這麼遠也。我希望有一種方法不涉及第二個ItemsControl – Richard 2011-01-31 17:18:07
