update panel

jack_hilary · December 1st, 2009, 09:10 AM

Hello sir,
I am working on contact.aspx page. I am using update panel with it to show the waiting image. It is working fine. But when I use the file attachment to it then file does not get sent with the message, but if I remove the update panel then it works fine.

my code for the markup (ContactForm.ascx) is

Code:

<asp:UpdatePanel ID="UpdatePanel1" runat ="server" >
<ContentTemplate >
<table class="style1" runat="server" id="FormTable">
    
same as in book. The extra field is file upload...

        <td align="right" class="style16">
            Attach Your File ( If Any ):</td>
        <td class="style5">
            <asp:FileUpload ID="FileUpload1" runat="server" Font-Bold="True" 
                Font-Italic="True" ForeColor="#39561D" />
        </td>
        <td class="style15">
        </td>
    </tr>
    <tr>
        <td class="style3" align="right">
            &nbsp;</td>
        <td class="style2">
         
           <asp:Button ID="btnSend" runat="server" Text="Submit Feedback" Font-Bold="True" Font-Italic="True" 
                ForeColor="#39561D" />
        </td>
        <td>
            &nbsp;</td>
    </tr>
    <tr>
        <td class="style7" colspan="3">
            <asp:ValidationSummary ID="ValidationSummary1" runat="server" 
                HeaderText="Please Correct The Following Errors Before You Press The Button" 
                Height="156px" Font-Bold="True" Font-Italic="True" ShowMessageBox="True" />
        </td>
    </tr>
</table>
<asp:Label ID="lblMessage" runat="server" Text="Message Sent" Visible="false"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID ="UpdatePanel1">
<ProgressTemplate >
<div class="PleaseWait">Please Wait...</div>
</ProgressTemplate>
</asp:UpdateProgress>

And the code behind file is

Code:

Protected Sub btnSend_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSend.Click
        If Page.IsValid Then

            Dim fileName As String = Server.MapPath("~/App_Data/FeedbackForm.txt")
           

            Dim mailBody As String = System.IO.File.ReadAllText(fileName)
            mailBody = mailBody.Replace("##Name##", txtName.Text)
            mailBody = mailBody.Replace("##Email##", txtEmailAddress.Text)
            mailBody = mailBody.Replace("##HomePhone##", txtPhoneHome.Text)
            mailBody = mailBody.Replace("##BusinessPhone##", txtPhoneBusiness.Text)
            mailBody = mailBody.Replace("##Comments##", txtComments.Text)

            Dim myMessage As New MailMessage()
            myMessage.Subject = "Feedback From Web Site"
            myMessage.Body = mailBody
            
            myMessage.From = New MailAddress("[email protected]", "Name")
            myMessage.To.Add(New MailAddress("[email protected]", "Name"))

            If FileUpload1.HasFile Then
                Dim fileName1 As String = Path.GetFileName(FileUpload1.PostedFile.FileName)
                Dim myAttachment As New Attachment(FileUpload1.FileContent, fileName1)
                myMessage.Attachments.Add(myAttachment)
            End If
            Dim mySmtpClient As New SmtpClient()
            Try
                mySmtpClient.EnableSsl = True
                mySmtpClient.Send(myMessage)
            Catch ex As Exception
                'ex.Message.ToString();
                lblMessage.Text = "Sorry,An Error Occurred While Sending Your Message. Please Try Again."
            End Try

            lblMessage.Visible = True
           
            FormTable.Visible = False
        End If
    End Sub

Any help is most appreciated.
Thank you.

You'd be surprised to learn what a Google search for "UpdatePanel FileUpload" (incidentally, the two controls you're working with) brings you:

http://www.google.com/search?hl=en&s...oq=&aqi=g3g-m2

Voila; instant results. The two are, by design, not compatible. But if you read on you'll find some work arounds including the AsyncFileUpload control.

In other words: GIYF, or STFW..... ;-)

How hard can it be....

Hello sir,
thank you for previous post. Now file Uploading is working fine but another issue comes into picture. Now updateprogress is not working. The link you provided, recommends about using trigger, but having triggers used update progress does not work.

Code:

</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID ="btnSend" />
</Triggers>
</asp:UpdatePanel>
<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID ="UpdatePanel1">
<ProgressTemplate >
    <div class="PleaseWait">Please Wait...</div>
</ProgressTemplate>
</asp:UpdateProgress>

I made many searches on this but no useful answer was there.
Any suggestion????
Thank you once again.

You're doing a full post back now....

Yes It is full post post back but these two tasks do not seem to be compatible. If I use trigger then progress does not work. So is there any way to use both????

Thank you sir once again.

Did you read my previous post? Did you follow the Google link? Did you read the first 20 odd results? Did you Google to find out what the AsyncFileUpload control is?
