从列表框中删除自定义项 [英] delete custom items from listbox

问题描述

我有一个包含自定义项目，文本块和复选框的列表框：

i have a listbox with custom items, textblock and checkbox:

<UserControl x:Class="kashtat.Listboxitems"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    FontFamily="{StaticResource PhoneFontFamilyNormal}"
    FontSize="{StaticResource PhoneFontSizeNormal}"
    Foreground="{StaticResource PhoneForegroundBrush}" Height="62" Width="284">

    <Grid x:Name="LayoutRoot" Background="{StaticResource PhoneChromeBrush}">
        <TextBlock x:Name="title" HorizontalAlignment="Left" Margin="10,10,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="202" Height="42"/>
        <CheckBox x:Name="condetion" Content="" HorizontalAlignment="Left" Margin="217,-9,-39,-31" VerticalAlignment="Top" Width="100" Height="90"/>

    </Grid>
</UserControl>

我有这个代码用于添加itmes（locationslistboxedit是列表框的名称）：

and i have this code for adding itmes (locationslistboxedit is the name of the listbox):

For t = 1 To 1000

            If locations(t, 0) <> "" Then
                Dim costumlistboxitem As Listboxitems = New Listboxitems
                costumlistboxitem.condetion.IsChecked = False
                costumlistboxitem.title.Text = locations(t, 0)
                locationslistboxedit.Items.Add(costumlistboxitem)
            End If
        Next

i想要删除被检查的项目。我该怎么做？

i want to delete the items which is checked. how can i do that?

推荐答案

尝试CheckBox控件或ListBox的DataContext属性。 SelectedItem属性获取所选CheckBox的ListBoxItems控件。

Try DataContext property of CheckBox control or ListBox.SelectedItem property to get ListBoxItems control for selected CheckBox.

Dim result as ListBoxItems = CType(sender, CheckBox).DataContext
locationslistboxedit.Items.Remove(result)
