You can get the selected row value when click on the row by using the SelectionChanged event in SfDataGrid.

void sfDataGrid_SelectionChanged(object sender, Syncfusion.WinForms.DataGrid.Events.SelectionChangedEventArgs e)
{
    var selectedItem = this.sfDataGrid.CurrentItem as DataRowView;
    var dataRow = (selectedItem as DataRowView).Row;
    var cellValue = dataRow["ID"].ToString();
}

You can also get the selected row value in SelectedItems collection in SfDataGrid, by converting SelectedItem into underlying business object.  

Code Example:
var selectedItem = sfDataGrid.SelectedItems[0];
var dataRow = (selectedItem as DataRowView).Row;
var cellValue = dataRow["ID"].ToString();
