Hi Thomaz, 

Greetings from Syncfusion support. 

We suggest you to use the SelectRows method of Grid in OnRecordClick event handler to achieve this requirement. Please refer and use as like the codes below, 

<SfGrid @ref="Grid" DataSource="@Orders" AllowSelection="true" AllowPaging="true"> 

    <GridSelectionSettings Type="SelectionType.Multiple" CheckboxOnly="true"></GridSelectionSettings> 

    <GridEvents OnRecordClick="OnRecordClick" TValue="Order"></GridEvents> 

    ... 

</SfGrid> 

public List<double> SelectIndexes { get; set; }public void OnRecordClick(RecordClickEventArgs<Order> args){    SelectIndexes = new List<double>();    for (var i = 0; i <= args.RowIndex; i++)    {        SelectIndexes.Add(i);    }    Grid.SelectRows(SelectIndexes);}

We are also attaching the sample for your reference, please download the sample from the link below,
