Question

我在asp.net中有回复表格。我想在发送按钮上点击按钮文字应该从发送到请等待＆amp;一旦发送它应该回到它的默认值文本'发送'。任何人都可以帮忙吗？

代码

Protected Sub submit_client_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit_client.Click
        Try
            Dim pattern As String
            pattern = "^([0-9a-zA-Z]([-\.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$"
            If Regex.IsMatch(TextBox3.Text, pattern) Then
                Label2.Text = ""
            Else
                Label2.Text = "Not a valid Email address "
            End If

            Dim emails As New List(Of String)()

            generate.Visible = True
            clear.Visible = True

            SendHTMLMail()

            'For Each item As ListViewItem In lvCustomers.Items
            '    Dim ck As CheckBox = DirectCast(item.FindControl("CheckBox1"), CheckBox)
            '    If ck.Checked Then
        Catch ex As Exception
            Response.Write(ex)
        End Try

    End Sub

尝试这样：

  MyButton.Text="Sending"

  SendHTMLMail()         

  Thread.Sleep(3000)       // add this & remove SendHTMLMail() for testing

  MyButton.Text="Send"

在按钮上单击更改按钮值文本
