我需要動態更改特定部分的項目模板 。 我怎樣才能做到這一點。 該部分將包含圖像，我們需要更改整個Item模板，然后在數據透視圖中進行重定向。 如何獲取方案。
以下是特定部分需要綁定的圖像設計
如下第一項
同樣，它包含項目列表。 在點擊每個部分時，重定向到下面
在點擊單個圖像時，我們將
點擊將重定向到以下部分
以上過程將在單個樞紐項目中執行。 有可能嗎 如果可能的話，如何做到這一點。 請有人指導我解決這個問題
根據我的理解，將建議您可以實現此目標的一些方法
<Pivot >...
<PivotItem x:Uid="OVERVIEW" Header="" Margin="0">
<Grid>...
</Grid>
</PivotItem>.......
</Pivot>
將為該數據透視表項目內的特定數據透視表指定ItemTemplate。 如果更改是針對每個樞紐的
另一種方式是使用此鏈接，您甚至可以使用Converters，並且基於數據可以使網格可見不可見等。但是您將需要確定所更改的ItemTemplate觸發器基於什么。
