如何在绑定的listboxitem上禁用点击事件？

我设法将项目的可见性设置为false，但这还不够，因为即使项目不可见，当单击该区域时它仍然会触发事件。这是我的项目：

<DataTemplate x:Key="stolTemplate1">
        <Grid Visibility="{Binding konobar, Converter={StaticResource IsItMyTable}}"  Height="155"  Width="155">
            <Grid.Background>
                <ImageBrush ImageSource="{Binding suma, Converter={StaticResource tablePictureConverter}}"/>
            </Grid.Background>
            <Grid Height="27" Width="Auto" Visibility="{Binding suma, Converter={StaticResource IsItMyTable2}}" VerticalAlignment="Bottom" Margin="45,0,45,128">
                <Grid.Effect>
                    <DropShadowEffect/>
                </Grid.Effect>
                <Grid.Background>
                    <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                        <GradientStop Color="{DynamicResource tipkeNarPlaG1Color}" Offset="0"/>
                        <GradientStop Color="#FF1E4D57" Offset="1"/>
                    </LinearGradientBrush>
                </Grid.Background>
                <Label Content="{Binding suma}"  Foreground="White" HorizontalAlignment="Center" FontWeight="Bold" FontSize="16">
                    <Label.Effect>
                        <DropShadowEffect/>
                    </Label.Effect>
                </Label>
            </Grid>
            <Label x:Name="label" Content="{Binding broj_stola}" HorizontalAlignment="Stretch" Margin="0" VerticalAlignment="Stretch" Height="Auto" Width="Auto" VerticalContentAlignment="Center" HorizontalContentAlignment="Center" Foreground="Black" FontSize="26.667" Background="{x:Null}" FontWeight="Bold"/>
        </Grid>
    </DataTemplate>

此部分：

<Grid Visibility="{Binding konobar, Converter={StaticResource IsItMyTable}}"

调用此部分：

 Private Function IValueConverter_Convert(value As Object, targetType As Type, parameter As Object, culture As CultureInfo) As Object Implements IValueConverter.Convert
   If value = Globals.konobar Or value = 0 Then Return Visibility.visible
    Return Visibility.Collapsed
End Function

我希望它不是Isvisible = IsEnabled = False / True。

我是通过ItemTemplate还是通过ItemContainer实现此目标？

好吧，有几种方法可以做到这一点：

快速又肮脏：为 IsEnabled 属性
创建一个额外的转换器
<Grid Visibility="{Binding konobar, Converter={StaticResource IsItMyTable}, IsEnabled={StaticResource YOUR_ISENABLED_CONVERTER}}"
在视图模型中创建一个布尔值，并将其绑定到您的Visibility和IsEnabled / IsHitTestVisible属性
创建一个依赖项属性（“ propdp”代码段）并将其绑定到您的属性
根据您的特定需求创建附加属性/行为

IMO，最好在您的视图模型中执行所有“逻辑约束”。
