in attached screenshot, I need to make all rows expanded always, so that I can select only radio button at a time. as of I now if I select a row and collapse it, it allows to choose another value from expanded rows. which cause application to crash, I need to keep only one selected radio button value from all available rows.
code for radio button below:
<StackPanel Orientation="Horizontal">
<RadioButton
Margin="0,0,10,0"
VerticalAlignment="Center"
GroupName="IndexedValue"
IsChecked="{Binding IsIndexedValue}" ToolTip="Select Only 1 value for indexing">
<RadioButton.Visibility>
<Binding
Converter="{StaticResource IsIndexedValueSelectedToVisibilityConverter}"
Path="DataContext.IsIndexedValueSelected"
Source="{x:Reference ParameterValueListView}"/>
</RadioButton.Visibility>
</RadioButton>
