我有一些绑定到gridview的数据，并想知道是否可以检索选定行中的值并将这些值插入一系列文本框或标签。从选定的行gridview检索值

是的，是的。 – EaterOfCode 2012-08-08 23:08:10

谢谢！我会研究这一点。 – user1512593 2012-08-08 23:19:31

那么FindControl实际上是否可以找到gridview中每个单元格的单个值？ – user1512593 2012-08-08 23:22:28

您可以在行或单元上使用它。例如'row.FindControl（“controlID”）'或'row.Cells [0] .FindControl（“coontrolID”）'。获取控件'TextBox txtName =（TextBox）row.FindContro（“txtName”）' – codingbiz 2012-08-08 23:27:19

正如@codingbiz说：你可以使用FindControl和TemplateField。

的例子：

EditGridView.aspx：
