Hi Rafael,
Thanks for using Syncfusion products.
You can make use of the ListBoxSelectionMode property for select the entire row when the cell is click.
[Xaml]
AutoPopulateRelations="False" ItemsSource="{StaticResource orderSource}"/>
[c#]
dataGrid.Model.Options.ListBoxSelectionMode = GridSelectionMode.One;
Please download the sample in the below location and check it out.

Thanks
