windows-phone-7 - 滚动查看器内的网格不起作用

Question

我在滚动查看器顶部添加了一个网格控件(我添加了大约 20 行，每行包含 2 列，每列都有文本 block 作为子项，我将 RowHeight 设置为 Auto)。它在滚动但不显示网格的全部内容。可能是什么原因？

Answer 1

问题是框架无法确定分配给控件的整体高度。尝试设置滚动查看器和/或网格的显式高度(如果可以的话)。

更新请发布您的确切代码。 (或者，至少是重现问题的代码。)

以下代码是我对您所描述内容的理解，但不会产生您正在经历的行为

<Grid x:Name="LayoutRoot" Background="Transparent">
    <controls:Pivot Title="MY APPLICATION">
