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"

Width="70"
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：
