Listbox datatemplate - 只能通过单击子元素来选择项目,而不仅仅是项目上的任何位置 [英] Listbox datatemplate - item only selectable by clicking a subelement, not just anywhere on the item
问题描述
我有一个包含项目数据模板的列表框。
问题在于,只需单击物品上的任意位置即可选择物品;我必须点击一个特定的子元素才能实际工作。
我的物品有一个图像和一个文本块。
如果将鼠标悬停在图像或文本块上,我实际上可以看到悬停效果。
如果我将鼠标悬停在项目的任何空白空间上,则不会有悬停效果(并且当我点击该空间时没有选择)。

如果我点击(或悬停)实际文字或图片,它可以正常工作,
但是如果我将鼠标悬停在空白区域(我画了一条红线
如何获取列表框悬停/点击以响应点击任何地方的 项目的空间?
为了完整性,我的列表框+模板:
< ListBox Grid.Row =1
ItemsSource ={Binding Path = CreatableOutputWindows,Mode = OneWay}Height =Auto
HorizontalAlignment =StretchVerticalAlignment =Stretch
Margin =8,8,8,8
Name =listBox1HorizontalContentAlignment =StretchVerticalContentAlignment =Stretch>
< ListBox.ItemTemplate>
< DataTemplate>
<网格>
< Grid.ColumnDefinitions>
< ColumnDefinition Width =84/>
< ColumnDefinition Width =*/>
< /Grid.ColumnDefinitions>
< Border Margin =5BorderBrush =BlackBorderThickness =2>
< / Border>
< StackPanel Grid.Column =1Margin =5>
< StackPanel Orientation =HorizontalTextBlock.FontWeight =Bold>
< TextBlock Text ={Binding Path = Name}/>
< / StackPanel>
< / StackPanel>
< / Grid>
< / DataTemplate>
< /ListBox.ItemTemplate>
< / ListBox>正如Quartermeister指出的那样 - 你需要设置Background(背景)的Grid - 但您还需要在资源中设置以下样式,因为默认情况下,ListBoxItems的HorizontalContentAlignment设置为Left。 (仅将它设置在ListBox上是不够的)
< ListBox.Resources>
< Style TargetType ={x:Type ListBoxItem}>
< Setter Property =HorizontalContentAlignmentValue =Stretch/>
< / style>
< /ListBox.Resources>
I have a listbox with a datatemplate for the items.
The problem is that selecting an item doesn't work by just clicking anywhere on the item; I have to click on a specific sub-element for it to actually work.
My item has an image and a textblock.
If I hover the mouse over the image or text-block, I actually see the hover-effect.
If I hover the mouse over any of the 'empty' space of the item, no hover effect (and no selection when I click there).
Example image : http://i33.tinypic.com/wvtleg.png
If I click on (or hover over) the actual text or the image it works fine,
but if i hover my mouse in the empty areas (I've drawn a red line around it :)) the listbox doesn't respond.
How do I get the listbox hovering / clicking to respond to clicking anywhere in the item's space ?
For completeness here is my Listbox + template:
<ListBox Grid.Row="1"
ItemsSource="{Binding Path=CreatableOutputWindows, Mode=OneWay}" Height="Auto"
HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
Margin="8,8,8,8"
Name="listBox1" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="84"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Border Margin="5" BorderBrush="Black" BorderThickness="2">
<Image Source="{Binding Path=Image}" Stretch="Fill" Width="80" Height="50" />
</Border>
<StackPanel Grid.Column="1" Margin="5">
<StackPanel Orientation="Horizontal" TextBlock.FontWeight="Bold">
<TextBlock Text="{Binding Path=Name}" />
</StackPanel>
</StackPanel>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
解决方案 As Quartermeister pointed out - you need to set the Background of the Grid - but you also need to set the following style in your resources as ListBoxItems' HorizontalContentAlignment is set to Left by default. (It isn't enough to set it on the ListBox)
<ListBox.Resources>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
</ListBox.Resources>
