如何从所选的gridview行中获取数据？

我想根据我选择删除的行从gridview中获取数据。如何从所选的gridview行中获取数据？

我想这一点，

string fileName = grdUploadedFiles.Rows[e.RowIndex].Cells[2].ToString();

，但它显示的字符串，

System.Web.UI.WebControls.DataControlFieldCell

我究竟能做些什么来取，我已经插入到GridView的文件名。

此外，此字段不是DataKey。

如果答案解决了您的问题，那么您应该“接受”它作为答案。 – jams 2011-05-20 05:10:25

如果cell不包含像label任何控制那就试试这个

string fileName = grdUploadedFiles.Rows[e.RowIndex].Cells[2].Text;

您应该调用.Text作为值，根据MSDN documentation。

一般来说，默认情况下，值类型会覆盖TooString。引用类型通常不会覆盖.ToSting及其“值”（调用该类时通常会访问的内容）。

这里是MSDN一个例子：

     (Object sender, GridViewDeleteEventArgs e) 
    { 
     TableCell cell = CustomersGridView.Rows[e.RowIndex].Cells[2]; 
     if (cell.Text == "Beaver") 
     { 
      e.Cancel = true; 
      Message.Text = "You cannot delete customer Beaver."; 
     } 
     else 
     { 
      Message.Text = ""; 
     } 
    }
