Question

我刚开始使用VS2013和Windows Phone SDK 8开始使用XAML。我在网格中有一些带有一些ComboBox控件的HubSection。当您打开ComboBox下拉列表时，它会在下拉列表中显示应该在其后面的控件。

有关如何解决此问题的任何建议？即使我可以单独打开下拉菜单（我还有另外一个包含13个项目的ComboBox，如果打开它会自动显示全屏）。

感谢您的帮助。

Answer 1

问题是控件位于网格内，这会导致控件相互叠加，除非您使用不同的行/列。但最简单的方法是使用StackPanel，这会导致元素自动水平或垂直堆叠。这意味着您不需要使用手动边距和对齐来获得良好的布局。

这是修改过的XAML，我还添加了一个ScrollViewer，以便让ComboBox扩展出视图：

<HubSection x:Uid="CharacterInfo" Header="Character Information" DataContext="{Binding Groups}">
    <DataTemplate>
        <ScrollViewer>
            <StackPanel>
                <TextBlock TextWrapping="Wrap" Text="Character Name:" FontSize="18"/>
                <TextBox TextWrapping="Wrap" Text="TextBox"/>

                <TextBlock TextWrapping="Wrap" Text="Breed:" FontSize="18"/>
                <ComboBox>
                    <ComboBoxItem Tag="HOMID" IsSelected="True">Homid</ComboBoxItem>
                    <ComboBoxItem Tag="METIS">Metis</ComboBoxItem>
                    <ComboBoxItem Tag="LUPUS">Lupus</ComboBoxItem>
                </ComboBox>

                <TextBlock TextWrapping="Wrap" Text="Auspice:" FontSize="18"/>
                <ComboBox>
                    <ComboBoxItem Tag="RAGABASH" IsSelected="True">Ragabash (New Moon)</ComboBoxItem>
                    <ComboBoxItem Tag="THEURGE">Theurge (Crescent Moon)</ComboBoxItem>
                    <ComboBoxItem Tag="PHILODOX">Philodox (Half Moon)</ComboBoxItem>
                    <ComboBoxItem Tag="GALLIARD">Galliard (Gibbous Moon)</ComboBoxItem>
                    <ComboBoxItem Tag="AHROUN">Ahroun (Full Moon)</ComboBoxItem>
                </ComboBox>

                <TextBlock TextWrapping="Wrap" Text="Tribe:" FontSize="18"/>
                <ComboBox>
                    <ComboBoxItem Tag="BLACKFURIES" IsSelected="True">Black Furies</ComboBoxItem>
                    <ComboBoxItem Tag="BONEGNAWERS">Bone Gnawers</ComboBoxItem>
                    <ComboBoxItem Tag="CHILDRENOFGAIA">Children of Gaia</ComboBoxItem>

                    <ComboBoxItem Tag="GLASSWALKERS">Glass Walkers</ComboBoxItem>
                    <ComboBoxItem Tag="REDTALONS">Red Talons</ComboBoxItem>
                    <ComboBoxItem Tag="SHADOWLORDS">Shadow Lords</ComboBoxItem>
                    <ComboBoxItem Tag="SILENTSTRIDERS">Silent Striders</ComboBoxItem>
                    <ComboBoxItem Tag="SILVERFANGS">Silver Fangs</ComboBoxItem>
                    <ComboBoxItem Tag="STARGAZERS">Stargazers</ComboBoxItem>

                </ComboBox>
            </StackPanel>
        </ScrollViewer>
    </DataTemplate>
