推荐答案

在网格视图的行命令事件处理程序中，编写类似这样的代码

in your row command event handler of the grid view, code something like this

Private Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
 'create a variable to read the content of cell, the primary key of the record
       Dim myprimarykey As Integer
'read the value from the row(which is clicked) and cell (no) 
       myprimarykey=gridView1.Rows(e.CommandArgument).Cells.Item(0).Text
' write the code you want to be performed on it. e.g.
       MessageBox.Show("You pressed the button for the record" & myprimarykey)
end sub

您还可以利用e.CommandName(在设计gridview并添加按钮列时在按钮说明中输入命令名称)执行if-else，以检查按下了哪个按钮(如果网格提供了多种类型的按钮)

you can also utilize e.CommandName (put the commandname in button description when designing gridview and adding a button column,) perform if-else to check which button was pressed (if the grid offers more than one type of button)
