关闭ComboBox循环滚动 [英] Turning off ComboBox loop scroll

问题描述

我有一个ComboBox，可以让用户从列表中进行选择，但是当列表足够长时，它将开始自动环绕。例如，如果用户向下滚动足够远，他们将到达列表的末尾，然后在单个空白行之后找到列表的顶部。下拉选择列表永远不会真正结束，只会一直循环下去。

I have a ComboBox to let the user choose from a list, but when the list gets long enough it begins to automatically wrap around. For example, if the user scrolls far enough down they'll reach the end of the list and then find the top of the list just after a single blank row. The drop down selection list never really ends, it just keeps looping forever.

我如何删除此循环滚动功能，使用户仅到达列表末尾？

How can I remove this looping scroll feature so the user just reaches the end of list?

我的代码：

<ComboBox Name="listSelect" ItemsSource="{Binding DataInstance.ItemList}">
    <ComboBox.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding ItemNumber, Mode=OneWay}" />
        </DataTemplate>
    </ComboBox.ItemTemplate>
</ComboBox>

Possible solution from this article: http://netitude.bc3tech.net/2013/04/12/windows-8s-combobox-and-the-carouselpanel/

将此设置为您的ComboBox控件，这将覆盖默认面板：

Set this to your ComboBox control, this should overwrite the default panel:

 <ComboBox.ItemsPanel>
                <ItemsPanelTemplate>
                    <StackPanel Orientation="Vertical" />
                </ItemsPanelTemplate>
 </ComboBox.ItemsPanel>

这是编辑面板模板，因此最终代码为：

This is to edit the panel template, so your final code will be:

<ComboBox Name="listSelect" ItemsSource="{Binding DataInstance.ItemList}">
    <ComboBox.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding ItemNumber, Mode=OneWay}" />
        </DataTemplate>
    </ComboBox.ItemTemplate>
     <ComboBox.ItemsPanel>
                    <ItemsPanelTemplate>
                        <StackPanel Orientation="Vertical" />
                    </ItemsPanelTemplate>
     </ComboBox.ItemsPanel>
</ComboBox>
