Question

我们希望在更新时发送电子邮件。

如果gridview的autogenerateEditButton设置为true，我该怎么做？

以下是一个例子：

<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1" 
    AutoGenerateColumns="False" DataKeyNames="ID" AllowPaging="True" 
    OnRowDataBound="gvRowDataBound" **onRowUpdated="btnSendEmail_Click"** AutoGenerateEditButton="True">
    <Columns>
        <asp:BoundField DataField="date_stamp" HeaderText="Entry Date" ReadOnly = "true"
            SortExpression="date_stamp" />
    </Columns>
</asp:GridView>

我的电子邮件代码位于名为sub btnSendEmail_Click()的代码隐藏中。

    Protected Sub btnSendEmail_Click(ByVal sender As Object, ByVal e As GridViewUpdatedEventArgs)
        Dim cnn As SqlConnection
        'Dim param As SqlParameter
        Dim cmd As SqlCommand

        Dim sqlStr As String = ""
        Dim sqlStrD As String = ""

        Dim connStr As String = ConfigurationManager.ConnectionStrings("Database_DBConnectionString").ConnectionString

您需要btnSendEmail_Click()处理GridView的RowEditing event。在您的ASP代码中，您应该：

<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1"
     OnRowEditing="btnSendEmail_Click"
     ...
     AutoGenerateEditButton="True">

然后在你的代码隐藏中：

Protected Sub btnSendEmail_Click(ByVal sender As Object, ByVal e As GridViewEditEventArgs)
    '...code to send email...

为什么不创建一个钩子来处理Gridview的RowUpadated事件，而不是使用“发送电子邮件”按钮并依赖用户手动点击它？

  void GridView1_RowUpdated(Object sender, GridViewUpdatedEventArgs e)
  {

    // Indicate whether the update operation succeeded.
    if(e.Exception == null)
    {
      int index = GridView1.EditIndex;
      GridViewRow row = GridView1.Rows(index);
      //example to pull the data from a cell to send it to your function
      SendEmail(row.Cells(0).Text);

      Message.Text = "Row updated successfully. Email Sent!";
    }
    else
    {
      e.ExceptionHandled = true;
      Message.Text = "An error occurred while attempting to update the row. No email sent.";
    }

  }

VB代码：

Private Sub GridView1_RowUpdated(sender As Object, e As GridViewUpdatedEventArgs)

    ' Indicate whether the update operation succeeded.
    If e.Exception Is Nothing Then
        Dim index As Integer = GridView1.EditIndex
        Dim row As GridViewRow = GridView1.Rows(index)
        'example to pull the data from a cell to send it to your function
        SendEmail(row.Cells(0).Text)

        Message.Text = "Row updated successfully. Email Sent!"
    Else
        e.ExceptionHandled = True
        Message.Text = "An error occurred while attempting to update the row. No email sent."
    End If

End Sub

编辑评论 我使用参数作为示例向您展示如果要传递它，如何从gridview中提取值。像这样：

SendEmail

Protected Sub SendEmail(ByVal RowNumber as Integer)
    Try
        Const ToAddress As String = "ThierEmail@domain.com"
        Const FromAddress As String = "YourEmail@domain.com"
        Dim Subject As String = "Row Updated"

        Dim mm As New MailMessage(FromAddress, ToAddress)
        mm.Subject = Subject
        mm.IsBodyHtml = False

        mm.Priority = MailPriority.High
        mm.Body =  String.Format("Row ID {0} was updated.",RowNumber)

        'Send the email
        Dim smtp As New SmtpClient()
          smtp.Send(mm)
    Catch ex As Exception
        'You should catch your error here
        Throw ex
    End Try
End Sub
