DevExpress gridcontrol how we get selected row values in gridview keydown event

//RowClick Event for to detect the row to press click on GridView
private void myGrid_RowClick(object sender, DevExpress.XtraGrid.Views.Base.RowClickEventArgs e) {
    //Validating selected row
    if (e.RowHandle < 0) {
        //Writing code for invalid row selected
    } else {
        //Recover information about row using some method: GetRow(), GetRowCellValue(), etc
        register = (MyClass)myGrid.GetRow(e.RowHandle)).ShallowCopy();
        oneValueOfCellOfRow = myGrid.GetRowCellValue(e.RowHandle, "OneNameOfFieldNameOfGrid");
    }
}

//FocusedRowClick for detect when you move into grid with directons keys
private void myGrid_FocusedRowChanged(object sender, DevExpress.XtraGrid.Views.Base.FocusedRowChangedEventArgs e) {
    //Validating selected row
    if (e.FocusedRowHandle < 0) {
        //Writing code for invalid row selected
    } else {
        //Recover information about row using some method: GetRow(), GetRowCellValue(), etc
        register = (MyClass)myGrid.GetRow(e.FocusedRowHandle));
        oneValueOfCellOfRow = myGrid.GetRowCellValue(e.FocusedRowHandle, "OneNameOfFieldNameOfGrid");
    }
}

List<myclass> data = new List<myclass>();
//Some code to fill the data (using POCOS)
...
//Assing the data to DataSource
myGrid.DataSource = data;
</myclass></myclass>
