C# 如何使启用时触发的复选框点击动作为false

在我的wp8应用程序中，我在列表框中有复选框，我希望能够在启用为false时点击复选框。我的意思是我想点击复选框，但选中时不应更改

<ListBox Name="URLListBox"  Height="Auto" Grid.Row="2"  >
    <ListBox.ItemTemplate>
       <DataTemplate>
         <Grid Background="Transparent" Margin="0,0,0,10" >   

            <CheckBox  IsChecked="{Binding file}"  x:Name="surename" Tag="{Binding b1Tag}" Grid.Column="0" FontSize="25" Content="{Binding text}" Tap="surename_Tap"  VerticalAlignment="Center" HorizontalAlignment="Center"></CheckBox>
         </Grid>
       </DataTemplate>
     </ListBox.ItemTemplate>
 </ListBox>

您可以通过在Listbox内声明该复选框并勾选Listbox点击事件上的复选框来进行编辑。像这样,

        <ListBox Name="listBox" Tap="listBox_Tap">
            <CheckBox Content="sample" IsEnabled="False" Name="checkBox" />
        </ListBox>

如果该列表框中有多个复选框，请在列表框点击事件中获取SelectedIndex并更改该复选框值。在您的例子中，您可以从以下代码中引用xaml

<ListBox Grid.Row="1" Tap="RoleslistBox_Tap" Name="RoleslistBox">
                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <CheckBox IsEnabled="False" Content="{Binding RoleTypes}" />
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>

在RoleslistBox点击事件中，你可以写

private void RoleslistBox_Tap(object sender, System.Windows.Input.GestureEventArgs e)
    {
        int i = RoleslistBox.SelectedIndex;
        ListBoxItem item = this.RoleslistBox.ItemContainerGenerator.ContainerFromIndex(i) as ListBoxItem;
        CheckBox tagregCheckBox = FindFirstElementInVisualTree<CheckBox>(item);
        tagregCheckBox.IsChecked = true;
    }

private T FindFirstElementInVisualTree<T>(DependencyObject parentElement) where T : DependencyObject
    {
        var count = VisualTreeHelper.GetChildrenCount(parentElement);
        if (count == 0)
            return null;

        for (int i = 0; i < count; i++)
        {
            var child = VisualTreeHelper.GetChild(parentElement, i);

            if (child != null && child is T)
            {
                return (T)child;
            }
            else
            {
                var result = FindFirstElementInVisualTree<T>(child);
                if (result != null)
                    return result;

            }
        }
        return null;
    }

private void RoleslistBox\u点击（对象发送方，System.Windows.Input.GestureEventArgs e）
{
int i=角色列表框。选择的索引；
ListBoxItem=this.RoleslistBox.ItemContainerGenerator.ContainerFromIndex（i）作为ListBoxItem；
复选框tagregCheckBox=FindFirstElementVisualTree（项目）；
tagregCheckBox.IsChecked=true；
}
私有T FindFirstElementVisualTree（DependencyObject parentElement），其中T:DependencyObject
{
var count=VisualTreeHelper.GetChildrenCount（parentElement）；
如果（计数=0）
返回null；
for（int i=0；i

您不想勾选该复选框，当该复选框被右键点击时？

private void RoleslistBox_Tap(object sender, System.Windows.Input.GestureEventArgs e)
    {
        int i = RoleslistBox.SelectedIndex;
        ListBoxItem item = this.RoleslistBox.ItemContainerGenerator.ContainerFromIndex(i) as ListBoxItem;
        CheckBox tagregCheckBox = FindFirstElementInVisualTree<CheckBox>(item);
        tagregCheckBox.IsChecked = true;
    }

private T FindFirstElementInVisualTree<T>(DependencyObject parentElement) where T : DependencyObject
    {
        var count = VisualTreeHelper.GetChildrenCount(parentElement);
        if (count == 0)
            return null;

        for (int i = 0; i < count; i++)
        {
            var child = VisualTreeHelper.GetChild(parentElement, i);

            if (child != null && child is T)
            {
                return (T)child;
            }
            else
            {
                var result = FindFirstElementInVisualTree<T>(child);
                if (result != null)
                    return result;

            }
        }
        return null;
    }
