                if (div.style.display == "none") {
                    div.style.display = "block"; img.src = "Images/Icons/minus.jpg";
                } else { div.style.display = "none"; img.src = "Images/Icons/plus.jpg"; }

我用VB代码对问题进行了排序。如果它可以帮助某人

，请参见下文

Protected Sub GV_SL_RowCommand(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs)
    If (e.CommandName = "AddText") Then
        ' Retrieve the row index stored in the CommandArgument property.
        Dim index As Integer = Convert.ToInt32(e.CommandArgument)

        ' Retrieve the row that contains the button 
        ' from the Rows collection.
        Dim row As GridViewRow = GV_SL.Rows(index)
        Dim GroupName As String = GV_SL.Rows(index).Cells(1).Text

        'Rest of the code here

    End If
End Sub

将嵌套gridview的值分配给CommandName
