如何在rad网格页脚中获得总和的总和。

我试过

<telerik:GridNumericColumn UniqueName="Amount" DataField="Amount" HeaderText="Amount" FooterAggregateFormatString="{0}" DataType="System.Int32" Aggregate="Sum"> 
</telerik:GridNumericColumn>

Answer 1

int total=0;
for (int i=0; i < list.size(); i++){
    total = total + list.get(i).price;
}
Log.e("sum of column", total + " - " );

Answer 2

根据他们的手册，这应该工作得很好

<telerik:GridNumericColumn UniqueName="Amount" DataField="Amount" HeaderText="Amount" DataFormatString="{0:C}" DataType="System.Double" Aggregate="Sum"> </telerik:GridNumericColumn>
