Implementing Send Mail Message

This tutorial elaborates on how to implement the SendMailMessage method required for sending email messages through report viewers that are connected to a Reporting REST Service.

Controllers Setup

When the Reporting REST Service has been implemented using controllers, override the SendMailMessage method of the ReportsController.

C#

protected override HttpStatusCode SendMailMessage(MailMessage mailMessage)
{
    using (var smtpClient = new SmtpClient("smtp.companyname.com", 25))
    {
        smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
        smtpClient.EnableSsl = true;
        smtpClient.Send(mailMessage);
    }

    return HttpStatusCode.OK;
}

VB.NET

Protected Overrides Function SendMailMessage(ByVal mailMessage As MailMessage) As HttpStatusCode
    Using smtpClient = New SmtpClient("smtp.companyname.com", 25)
        smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network
        smtpClient.EnableSsl = True
        smtpClient.Send(mailMessage)
    End Using

    Return HttpStatusCode.OK
End Function

Minimal API Setup

When the Reporting REST Service has been implemented using Minimal API, first implement a method that sends the MailMessage object via the SmtpClient:

C#

public static HttpStatusCode MyMailSender(MailMessage message)
{
    try
    {
        using (var smtpClient = new SmtpClient("tests.com", 26))
        {
            smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
            smtpClient.Credentials = new NetworkCredential("user", "pass");
            smtpClient.EnableSsl = true;
            smtpClient.Send(message);
        }
        return HttpStatusCode.OK;
    }
    catch
    {
        return HttpStatusCode.InternalServerError;
    }
}

Then, this method can be passed alongside the ReportServiceConfiguration of the Reporting REST Service when adding it in the starting point of the application, for example, the Program.cs file:

C#

var mailContext = new MailContext(MyMailSender);
var reportServiceConfiguration = new ReportServiceConfiguration
{
    ReportingEngineConfiguration = builder.Configuration,
    HostAppId = "Reporting",
    Storage = new FileStorage(),
    ReportSourceResolver = new TypeReportSourceResolver()
                                .AddFallbackResolver(
                                    new UriReportSourceResolver(reportsPath))
};

builder.Services.AddRazorPages().AddTelerikReporting(reportServiceConfiguration, mailContext);
