我将一些数据绑定到gridview，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中

是的，这是可能的。使用

FindControl

方法

复制品

正如@codingbiz所说：您可以使用

FindControl

和

TemplateField

例如：

EditGridView.aspx：

完整来源：

谢谢！我将对此进行研究。那么FindControl是否真的可以找到gridview中每个单元格的单个值呢？您可以在行或单元格上使用它。e、 g.

row.FindControl（“controlID”）

或

row.Cells[0]。FindControl（“coontrolID”）

。获取控件

TextBox txtName=（TextBox）行。FindContro（“txtName”）

要查找单元格值，我认为它是

行。单元格[0]。Text

。请查证
