WPF中ListView的問題

請參閱附加圖片中的問題，並讓我知道如何解決它們，如果您知道。WPF中ListView的問題

- 如果我有大量的項目，一切都看起來不錯 - 如果周圍的6個項目，然後我在上面，滾動條的底部得到空的空間 - 如果3個或更少的項目，然後我得到的之間的不必要間距項目

immages是一個非常低的質量。更進一步，你的問題更爲廣泛。只需選擇一個問題，並將其與理解問題所需的信息，解決問題所需的信息以及描述不符合預期的內容結合起來。最後請在發佈此類問題之前閱讀本文：http://stackoverflow.com/help/how-to-ask – HimBromBeere

<ListView.ItemsPanel> 
    <ItemsPanelTemplate> 
     <UniformGrid Columns="1"/> 
    </ItemsPanelTemplate> 
</ListView.ItemsPanel>

這這裏是你的問題的根源。 UniformGrid正在使用整個可用空間並創建同樣高的單元格來填充它。

使用StackPanel作爲您的物品面板，或將VerticalAlignment="Top"設置爲UniformGrid。

非常感謝。這確實解決了物品之間間距的問題。我剛剛評論說，該塊。但是，滾動條頂部和底部的間距仍然存在。 – Ivan

我不明白「頂部和底部的滾動條間距」是什麼意思。我沒有看到圖像中的滾動條有任何問題。 – almulo

哦，在第二張圖片中，你會看到它如何不會一直向上......我沒有隨意將它放在那個位置。這是當我有大約6個項目時可以達到的最大值......並且同樣的東西適用於底部 – Ivan
