Hello!

Do you mean CheckboxSelectionModel?
If so, please follow the link https://examples1.ext.net/#/GridPane...box_Selection/.

There is a code to set selected row in code behind

Example

if (!this.IsPostBack)
{
RowSelectionModel sm = this.GridPanel1.SelectionModel.Primary as RowSelectionModel;

sm.SelectedRow = new SelectedRow(2);

sm.SelectedRows.Add(new SelectedRow(2));
sm.SelectedRows.Add(new SelectedRow("11"));
}

Also you can set some row as selected in markup.

<SelectionModel>
    <ext:CheckboxSelectionModel runat="server">
        <SelectedRows>
            <ext:SelectedRow RowIndex="0"/>
            <ext:SelectedRow RowIndex="5"/>
        </SelectedRows>
    </ext:CheckboxSelectionModel>
</SelectionModel>
