Question

i created multiple check boxes inside listbox but when i try to use these boxes in the c# code the code cant detect it but the check box outside the listbox is detected normally

this is the xaml list box

<code><ListBox x:Name="lb_mainElements" Grid.Row="2" Grid.ColumnSpan="2" Margin="10" Background="Transparent"

BorderThickness="0" SelectionChanged="ListBox_SelectionChanged_1">

<ListBox.ItemContainerStyle>

<Setter.Value>

<Grid>

<Grid.RowDefinitions>

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

</Grid>

</Border>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

</ListBox.ItemContainerStyle>

</ListBox>

</code>

                    <ControlTemplate TargetType="ListBoxItem" x:Name="cTemplate" >
                        <Border Background="Transparent" Padding="5">
                            <Grid>
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="*"/>

                                <Label Content="Main Elements" FontWeight="Bold" Grid.Row="0" Grid.Column="0"/>
                                <!-- Checkboxes in a 3x3 grid -->

            </Setter>
        </Style>
    </ListBox.ItemContainerStyle>
    <Label/>
</ListBox>

and this the c# code

<code>private void cbOtherCheckedChanged(object sender, RoutedEventArgs e)

{

bool newVal = (cbSelectAll.IsChecked == true);

cbFoundation.IsChecked = newVal;

cbColumns.IsChecked = newVal;

cbRwall.IsChecked = newVal;

cbSwall.IsChecked = newVal;

cbBeams.IsChecked = newVal;

cbStairs.IsChecked = newVal;

cbSog.IsChecked = newVal;

cbTanks.IsChecked = newVal;

}

</code>

<code>private void cbOtherCheckedChanged(object sender, RoutedEventArgs e) { bool newVal = (cbSelectAll.IsChecked == true); cbFoundation.IsChecked = newVal; cbColumns.IsChecked = newVal; cbRwall.IsChecked = newVal; cbSwall.IsChecked = newVal; cbBeams.IsChecked = newVal; cbStairs.IsChecked = newVal; cbSog.IsChecked = newVal; cbTanks.IsChecked = newVal; } </code>

private void cbOtherCheckedChanged(object sender, RoutedEventArgs e)
{
    bool newVal = (cbSelectAll.IsChecked == true);
   
    cbFoundation.IsChecked = newVal;
    cbColumns.IsChecked = newVal;
    cbRwall.IsChecked = newVal;
    cbSwall.IsChecked = newVal;
