<asp:AsyncPostBackTrigger ControlID = "GridView1" />
<asp:AsyncPostBackTrigger ControlID = "btnSave" />
</Triggers>  
        
        </asp:UpdatePanel>

调用以下过程的编辑工作非常好

  Protected Sub LnkEdit_Click(sender As Object, e As EventArgs)
        Using row As GridViewRow = DirectCast(DirectCast(sender, LinkButton).Parent.Parent, GridViewRow)
            Dim pk As String = GridView1.DataKeys(row.RowIndex).Values(0).ToString()
            Gridviewnotes = TryCast(GridView1.Rows(row.RowIndex).FindControl("lNotes"), Label)
            txtnotes.Text = Gridviewnotes.Text
            ID.Value = CInt(pk.ToString())
            popup.Show()
        End Using

    End Sub

但是；当我点击更新时，没有调用以下程序......有什么原因吗？我将目标控件 id 更改为标签，但它仍然没有调用下面的保存按钮事件单击。下面永远不会被调用...

Protected Sub Save(sender As Object, e As EventArgs)
        txtnotes.Text = Replace(txtnotes.Text, "'", Chr(34))
        Dim connString As String = ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString
        Dim myConnection As New SqlConnection(connString)
        Dim sql As String = ""
        Dim objCmd As New SqlCommand(sql, myConnection)
        myConnection.Open()
        objCmd.CommandText = "UPDATE Mytable SET ColumnName=@variable where Id=@ID "
        objCmd.CommandType = CommandType.Text
        objCmd.Parameters.AddWithValue("@Notes", @variable)
        objCmd.Parameters.AddWithValue("@FacpacketID", @ID))
        objCmd.ExecuteNonQuery()
        myConnection.Close()
        GridView1.DataBind()
    End Sub

感谢那些看过我的 post 的人，我终于找到了一种方法，通过使用一些 JavaScript post 返回并将以下内容添加到我的模态扩展程序弹出窗口它奏效了。希望这会帮助遇到同样问题的人

OkControlID="btnSave"  
         OnOkScript="__doPostBack('btnSave','')">
