如何在RadGrid的頁腳顯示列總數Telerik

Question

如何在Telerik的RadGrid頁腳顯示列總數？

Answer 1

您需要綁定到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(); 
     } 
} 

Answer 2

這是由Erik給出也在努力的解決方案。 但Radgrid有這個內置列。

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