You can subscribe the DropDownOpened event which will be triggered when you try to open the dropdown list or use IsDropDownOpen property to judge whether the drop-down portion of the ComboBox is currently open.

.xaml:

<ComboBox x:Name="MyComboBox" DropDownOpened="MyComboBox_DropDownOpened">
    <ComboBoxItem>123</ComboBoxItem>
</ComboBox>

.cpp:

void AppCX::MainPage::Button_Click(Platform::Object^ sender, Windows::UI::Xaml::RoutedEventArgs^ e)
{
    bool isOpen = MyComboBox->IsDropDownOpen;
}


void AppCX::MainPage::MyComboBox_DropDownOpened(Platform::Object^ sender, Platform::Object^ e)
{

}
