如何在 RadGrid Telerik 的页脚处显示总列数

Question

如何在 Telerik 中的 RadGrid 页脚显示列总数？

Answer 1

您需要绑定到 ItemDataBound 事件：

int counter = 0;

void Grid_ItemDataBound(object sender, Telerik.WebControls.GridItemEventArgs e) {
      if(e.Item is GridDataItem) {
         GridDataItem dataItem = e.Item as GridDataItem;
         counter += Convert.ToInt32(dataItem["SomeField"].Text);
      }
      else if(e.Item is GridFooterItem) {
         GridFooterItem footerItem = e.Item as GridFooterItem;
         FooterItem["YourFooterColumn"].Text = counter.ToString();
      }
 }

埃里克给出的解决方案也有效。
但 Radgrid 为此内置了列。

<telerik:GridCalculatedColumn HeaderText="Total Price" UniqueName="TotalPrice" DataType="System.Double"
                    DataFields="UnitPrice, UnitsInStock" Expression="{0}*{1}" FooterText="Total : "
                    Aggregate="Sum" />
