一、定义GridViewStyle
1).定义GridVeiwStyle 
    <s:EditorPage.Resources>
        <s:InvertedBooleanConverter x:Key="InvertedBooleanConverter" />
        <Style x:Key="GridViewStyle" TargetType="{x:Type s:SmartGridView}">
            <Setter Property="AutoGenerateColumns" Value="False" />
            <Setter Property="IsFilteringAllowed" Value="False" />
            <Setter Property="CanUserFreezeColumns" Value="True" />
            <Setter Property="FrozenColumnCount" Value="3" />
            <Setter Property="ShowColumnFooters" Value="True" />
            <Setter Property="ShowGroupPanel" Value="False" />
            <Setter Property="RowIndicatorVisibility" Value="Collapsed" />
        </Style>
    </s:EditorPage.Resources>
2).邦定Stytle 
        <s:SmartGridView 
                         Style="{StaticResource GridViewStyle}"
...>
二、合计
1).记录数、最大值、最小值...
                <s:SmartDataColumn Header="年度" IsReadOnly="True" Width="50" DataMemberBinding="{Binding aYear}">
                    <s:SmartDataColumn.AggregateFunctions>
                        <telerik:CountFunction Caption="筆數:" />
                    </s:SmartDataColumn.AggregateFunctions>
                </s:SmartDataColumn>
//注意:运行时会自动将 CountFunction 的但值放到“筆數:”后面
2).栏目合计
                <s:SmartDataColumn Header="本次收款"
DataFormatString="{}{0:0.00}"
DataMemberBinding="{Binding PayAmt}"
FooterTextAlignment="Right"
TextAlignment="Right">
<s:SmartDataColumn.AggregateFunctions>
<telerik:SumFunction ResultFormatString="{}{0:0.00}" SourceField="PayAmt" />
</s:SmartDataColumn.AggregateFunctions>
<s:SmartDataColumn.Footer>
<TextBlock Text="{Binding FormattedValue}" FontWeight="Bold" Foreground="Blue" />
</s:SmartDataColumn.Footer>
</s:SmartDataColumn>
三、行加入“操作”按钮
                <s:SmartDataColumn Header="操作" Width="40">
                    <s:SmartDataColumn.CellTemplate>
                        <DataTemplate>
                            <Button Content="付" Click="OnPayClick" />
                        </DataTemplate>
                    </s:SmartDataColumn.CellTemplate>
                </s:SmartDataColumn>
四、强行刷新“合计”
        private void OnPayClick(object sender, RoutedEventArgs e)
        {
            var rowView = (DataRowView)(sender as FrameworkElement).DataContext;
            if (rowView.Row.Field<decimal>("PayAmt") == 0)
            {
                rowView["PayAmt"] = rowView["RemainAmount"];
            }
            else
            {
                rowView["PayAmt"] = 0;
            }
            this.Grid.CalculateAggregates();    //刷新行合計
        }
效果如下图:
