Hello,

You can get the selected Radio button this way: < StackPanel x:Name="_stackPanel" HorizontalAlignment="Center"> <xctk:MaterialRadioButton x:Name="materialRadioButton" GroupName="Choice" IsChecked="True" Content="First" /> <xctk:MaterialRadioButton x:Name="materialRadioButton2" GroupName="Choice" Content="Second"/> <Button Content="TEST" Click="Button_Click" /> </StackPanel>

private void Button_Click( object sender, RoutedEventArgs e ) { var checkedButton = _stackPanel.Children.OfType<MaterialRadioButton>().FirstOrDefault( r => r.GroupName == "Choice" && r.IsChecked.Value ); }

You can also register to the Checked event on MaterialRadioButton: < xctk:MaterialRadioButton x:Name="materialRadioButton" GroupName="Choice" IsChecked="True" Content="First" Checked="materialRadioButton_Checked"/> < xctk:MaterialRadioButton x:Name="materialRadioButton2" GroupName="Choice" Content="Second" Checked="materialRadioButton_Checked"/>

private void materialRadioButton_Checked( object sender, RoutedEventArgs e ) { var radioButton = sender as MaterialRadioButton; if( radioButton != null ) { var isChecked = radioButton.IsChecked; } }

Remember that a MaterialRadioButton is a RadioButton. Thank you
