问题描述

我有一个comboBox,其样式设置为具有文本行和复选框,以允许用户检查不同内容的列表。我想做的是禁用组合框中的行选择。

I have a comboBox that is styled to have rows of text blocks and check boxes to allow user to check a list of different things. What I am attempting to do is disable selection of a row in the the combobox.

我的查看代码:

<ComboBox ItemsSource="{Binding HeaderList}" 
    IsSelected="False"
    HorizontalAlignment="Left"
    Height="10"
    x:Name="ComboBox">
    <ComboBox.ItemTemplate>
       <DataTemplate>
          <StackPanel Orientation="Horizontal">
             <CheckBox IsChecked="{Binding IsChecked}"/>
             <TextBlock Text="{Binding HeaderName}"/>
          </StackPanel>
       </DataTemplate>
    </ComboBox.ItemTemplate>
</ComboBox>

这是我的下拉菜单的图片:

这是我不喜欢的图片想要:

< img src = https://i.stack.imgur.com/vnAN7.png alt =在此处输入图片描述>

我要禁用用户选择特定行的功能,但保留用户在下拉菜单中选择各种复选框的功能。有样式的方法吗?

I want to disable the ability for the user to select a specific row, but keep the ability for them to select various check boxes in the drop down. Is there a way to style this?

推荐答案

我遇到了同样的问题,我通过使用 ToggleButton 与 Popup 组合(而不是使用 ComboBox

I had the same issue, i solved it by using a ToggleButton in combination with a Popup (instead of using a ComboBox)

注意:未测试

<ToggleButton x:Name="filterButton" />
<Popup x:Name="popup" 
    AllowsTransparency="True" 
    StaysOpen="False"
    PlacementTarget="{Binding ElementName=filterButton}"
    IsOpen="{Binding ElementName=filterButton,Path=IsChecked,Mode=TwoWay}">
    <ItemsControl ItemsSource="{Binding HeaderList}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <StackPanel Orientation="Horizontal">
                    <CheckBox IsChecked="{Binding IsChecked}"/>
                    <TextBlock Text="{Binding HeaderName}"/>
                </StackPanel>
            </DataTemplate>                                    
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</Popup>
