SfDataGrid provides two events for selection: SelectionChanging and SelectionChanged. It provides the added items and the removed items as arguments in it. You can pass the selected row info to a command in the ViewModel by using the Xamarin.Forms.Behaviors.

Refer the below code example in which a custom behavior for passing the selected row information to ViewModel is defined.

<?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:syncfusion="clr-namespace:Syncfusion.SfDataGrid.XForms;assembly=Syncfusion.SfDataGrid.XForms"

xmlns:local="clr-namespace:SelectionSample"

x:Class="SelectionSample.MainPage">

<ContentPage.BindingContext>

<local:ViewModel x:Name="viewModel" />

</ContentPage.BindingContext>

<ContentPage.Resources>

<local:CustomConverter x:Key="gridSelectionChangedEventArgs" />

</ResourceDictionary>

</ContentPage.Resources>

<syncfusion:SfDataGrid x:Name="dataGrid"

ColumnSizer="Star"

SelectionMode="Single"

ItemsSource="{Binding OrderInfo}">

<syncfusion:SfDataGrid.Behaviors>

<local:CustomBehavior Command="{Binding SelectionCommand}"

Converter="{StaticResource gridSelectionChangedEventArgs}" />

</syncfusion:SfDataGrid.Behaviors>

</syncfusion:SfDataGrid>
