如何在GridView telerik中添加页脚 [英] How to add Footer in GridView telerik

问题描述

您好，

我使用c＃在Telerik win表格中工作，



我有网格视图，我想添加页脚按下面的锯数计算单位。



我的代码如下。

 GridViewSummaryItem summaryItem =  new  GridViewSummaryItem（）; 
 summaryItem.Name =   Units; 
 summaryItem.Aggregate = GridAggregateFunction.Count; 
 
 GridViewSummaryRowItem summaryRowItem =  new  GridViewSummaryRowItem（）; 
 summaryRowItem.Add（summaryItem）; 
  this  .GridViewWorkInProgress.SummaryRowsTop.Add（summaryRowItem）; 
  this  .GridViewWorkInProgress.SummaryRowsBottom.Add（summaryRowItem）; 

我会抛出NullReference Exception Un错误的错误。



给我解决方案。





谢谢
