PowerShell\WPF: Emtpy Radio Button Object in PowerShell using datatemplate-CodePudding

I am currently using a data template for radio buttons and textblocks to be autogenerated by values pulled from an excel spreadsheet. It works however, I'm having an issue where the RadioButton object appears in my variable $form(wpf items) array but the value of it is null.

Here is my WPF. if you would like to see the PowerShell Code i can attach as well.

Here is a snippet of the GUI. Like mentioned above the display works however, the object in PowerShell is null and does not show up as an radio buttton which is my issue.

CodePudding user response：

I solved my issue by changing itemsControl to a listbox utilizing selectedValue, SelectedIndex to control my autogenerated radio buttons.

PowerShell Code

$wpf.menuListBox.add_SelectionChanged({
    $wpf.BtnNexttemplateMenu.IsEnabled = $true
    if($wpf.menuListBox.SelectedIndex -lt $wpf.menuListBox.Items.Count){
        $selectedItem = $wpf.menuListBox.SelectedValue.'Template Type'
    }
 })

Xaml Code

<ListBox x:Name="menuListBox"
                        ItemsSource="{Binding dataContent}"
