thanks for your reply. that solved my problem . it works well now.
but the Combo Box control has the same problem. and set MinHeight to it has no effect too.

1. Use DevTools F12 to inspect visual tree (maybe ComboBoxItem is limiting element here)
2. Check out <FluentTheme DensityStyle="Compact" /> in case you use FluentTheme
3. Check original styles: https://github.com/AvaloniaUI/Avalonia/blob/master/src/Avalonia.Themes.Fluent/Controls/ComboBox.xaml
