How to show context menu in .NET MAUI DataGrid?

The .NET MAUI DataGrid does not have built-in support for the context menu.
However, you can achieve this by loading FlyoutBase.ContextFlyout within a DataGrid and utilizing the CellRightTapped event.

XAML
Define your DataGrid with the required customizations. Embed the DataGrid with FlyoutBase.ContextFlyout containing your desired context menu items using MenuFlyoutItem.

<syncfusion:SfDataGrid  x:Name="dataGrid" 
            ItemsSource="{Binding Employees}" >
    <FlyoutBase.ContextFlyout>
        <MenuFlyout>
            <MenuFlyoutItem Text="Sort" 
                Command="{Binding SortCommand}" 
                CommandParameter="{x:Reference dataGrid}"  />
            <MenuFlyoutItem Text="Clear Sort" 
                Command="{Binding ClearSortCommand}" 
                CommandParameter="{x:Reference dataGrid}"  />
        </MenuFlyout>
    </FlyoutBase.ContextFlyout>
</syncfusion:SfDataGrid>

C#
MainPage.cs
Within the DataGridCellRightTappedEventArgs, we will get the RowColumnIndex of the clicked DataGridCell.

public partial class MainPage : ContentPage
{
   public MainPage()
   {
       InitializeComponent();
       dataGrid.CellRightTapped += DataGrid_CellRightTapped;
   }

   private void DataGrid_CellRightTapped(object sender, DataGridCellRightTappedEventArgs e)
   {
       viewModel.currentColumnName = dataGrid.Columns[e.RowColumnIndex.ColumnIndex].MappingName;
   }        
}

ViewModel.cs
In the ViewModel class, create the necessary commands and logic to sort and unsort a DataGridColumn.

public class EmployeeViewModel
{
   public ICommand SortCommand { get; set; }
   public ICommand ClearSortCommand { get; set; }
   public string currentColumnName { get; set; }
   
   public EmployeeViewModel()
   {
       SortCommand = new Command(SortColumn);
       ClearSortCommand = new Command(ClearSort);
   }

   private void ClearSort(object sender)
   {
       var dataGrid = sender as SfDataGrid;
       if (dataGrid.SortColumnDescriptions.Count > 0)
           dataGrid.SortColumnDescriptions.Clear();
       else
           Application.Current.MainPage.DisplayAlert("Warning","Column is not sorted","Ok");
   }

   private void SortColumn(object sender)
   {
       var dataGrid = sender as SfDataGrid;
       dataGrid.SortColumnDescriptions.Clear();
       dataGrid.SortColumnDescriptions.Add(new SortColumnDescription()
       {
           ColumnName = currentColumnName,
           SortDirection = ListSortDirection.Ascending,
       });

   }
}
