Export RadGrid only to email

[Daniel]

Hi

I am using RadGrid and I need to export it to email.
I looked in your forums and found this answer:

VB.NET:

01.Private Sub RadGrid1_GridExporting(sender As Object, e As GridExportingArgs) Handles RadGrid1.GridExporting
02.
03.    If isLoc <> True Then
04.
05.        Dim ms As New MemoryStream(New UTF8Encoding().GetBytes(e.ExportOutput))
06.
07.        Dim smtpClient As New SmtpClient()
08.        smtpClient.EnableSsl = True
09.
10.        Dim mailMessage As New MailMessage()
11.        mailMessage.IsBodyHtml = True
12.        mailMessage.[To].Add(New MailAddress(Session("Email")))
13.        mailMessage.Subject = "Reporting service - Do Not reply"
14.        mailMessage.Body = "This report was sent from <br /><b>Reporting service</b> "
15.        mailMessage.Attachments.Add(New Attachment(ms, "Reporting service" & DocType))
16.        Try
17.            smtpClient.Send(mailMessage)
18.            'Label1.Text = "Message Sent"
19.            MsgBox("Message Sent")
20.        Catch ex As Exception
21.            'Label1.Text = ex.ToString()
22.            MsgBox("Message not Sent")
23.        End Try
24.
25.        Response.Redirect(Request.Url.ToString())
26.
27.
28.
29.    End If
30.End Sub

The code in line 25 is not good for my project
because if I use the Response command it does a PostBack.
In my project the PostBack resets user configuration.
And if I delete the Response command, it sends an email and also creates a file in the user's computer.

I want only to send an email without PostBack and without creating a file in the user's computer.
How can I do that?

Thanks,
Daniel.

Hi,

I had a mistake on the previous question.

The right question is:
My problem is that the Response command DOES NOT DO a PostBack and because of that,
when I call the Response command, it goes to:

If Not IsPostBack Then
' first initialization settings

 ,and resets user configuration.


I want only to send an email with PostBack and without creating a file in the user's computer.
How can I do that?

Thanks,
Daniel.

Hello Daniel,

A possible way around this issue would be to use a simple session flag which could help you avoid resetting the user configuration. Runnable demo below:

Public Property IsRefresh() As Boolean
    Get
        If Session("IsRefresh") Is Nothing Then
            Return False
        End If
        Return CBool(Session("IsRefresh"))
    End Get
    Set
        Session("IsRefresh") = value
    End Set
End Property
Protected Sub Page_Init(sender As Object, e As EventArgs)
    Button1.Click += Function(s, a)
    Response.Redirect(Request.Url.ToString())

End Function
    Button2.Click += Function(s, a)
    IsRefresh = True
    Response.Redirect(Request.Url.ToString())

End Function

    If Not IsPostBack AndAlso Not IsRefresh Then
        Response.Write("Resetting user settings...")
    Else
        Response.Write("User settings persisted")
    End If

    IsRefresh = False
End Sub

<asp:Button ID="Button1" runat="server" Text="Redirect" />
<asp:Button ID="Button2" runat="server" Text="Refresh" />

I hope this helps.

Hi Daniel.

Indeed it has solved some of the problems,
But I have more problem:
When the user makes exporting,  all of the data in the grid disappear.
In my Website I have one page and the grids change only by functions (the page stay the same page). 
When I call RESPONSE command,  
the data on the grid disappears and the  data user reset.

Hello Daniel,

I suppose the problem is in the way the RadGrid is bound. You can use that flag to determine whether you have to repopulate it with data or not.
