How to both execute Command and Button click in Xamarin - xamarin

Question

I have:
<Grid.GestureRecognizers>
<TapGestureRecognizer NumberOfTapsRequired="1" Command="{Binding Source={RelativeSource AncestorType={x:Type locals:OneViewModel}},
Path=OneTappedView}" CommandParameter="{Binding .}" />
</Grid.GestureRecognizers>
<Button x:Name="bt_one" Clicked="bt_one_Clicked"/>
When I do Grid Tap, Command and bt_one_Clicked execute concurrently? Thank you

When I do Grid Tap, Command and bt_one_Clicked execute concurrently?
Yes, you can add the button's clicked code in your grid tap event when tapping your grid.
You can refer to the following code:
OnePage.xml
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:formapp1="clr-namespace:FormApp1"
x:Class="FormApp1.OnePage">
<ContentPage.BindingContext>
<formapp1:OneViewModel></formapp1:OneViewModel>
</ContentPage.BindingContext>
<ContentPage.Content>
<StackLayout>
<Grid WidthRequest="300" HeightRequest="600" BackgroundColor="Yellow">
<Grid.GestureRecognizers>
<TapGestureRecognizer NumberOfTapsRequired="1" Command="{Binding OneTappedViewCommand}" />
</Grid.GestureRecognizers>
</Grid>
<Button x:Name="bt_one" Text="one button" Command="{Binding BtnOneClickedCommand}"/>
</StackLayout>
</ContentPage.Content>
</ContentPage>
OneViewModel.cs
public class OneViewModel: INotifyPropertyChanged
{
public ICommand OneTappedViewCommand { private set; get; }
public ICommand BtnOneClickedCommand { private set; get; }
public OneViewModel() {
OneTappedViewCommand = new Command(GridTapped);
BtnOneClickedCommand= new Command(btnOneClickedMthod);
}
private void GridTapped()
{
System.Diagnostics.Debug.WriteLine("----111------> GridTapped is triggered......");
//add one clicked method here
btnOneClickedMthod();
}
private void btnOneClickedMthod()
{
System.Diagnostics.Debug.WriteLine("----222------> GridTapped is triggered......");
}
bool SetProperty<T>(ref T storage, T value, [CallerMemberName] string propertyName = null)
{
if (Object.Equals(storage, value))
return false;
storage = value;
OnPropertyChanged(propertyName);
return true;
}
protected void OnPropertyChanged([CallerMemberName] string propertyName = null)
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
public event PropertyChangedEventHandler PropertyChanged;
}
Note:
In model OneViewModel, you can add bt_one event(btnOneClickedMthod) in grid tap function GridTapped.
