Custom Actions

Add user defined buttons to the toolbar and invoke custom actions using the Report Viewer property. You can create a custom email button with the rendered report to users.

Add email button

1. Create an email button in the toolbar using the CustomItems property with the values such as GroupIndex, Index, Type, CssClass, and Tooltip. The tool-bar-item-click event triggers when you click the email button.

2. Access the Report Viewer model and create a JSON array for sending requests to the Web API Server.

3. You can use the following codes to add email button from controller and passing the data to view using ViewBag.

       public ActionResult Index()
       {
           ToolbarSettings toolbarSettings = new ToolbarSettings();
           toolbarSettings.CustomItems = new List<CustomItem>();
   
           var customItem = new CustomItem()
           {
               GroupIndex = 1,
               Index = 1,
               CssClass = "e-icon e-mail e-reportviewer-icon",
               Type = BoldReports.ReportViewerEnums.ToolBarItemType.Default,
               Id = "E-Mail",
               Tooltip = new ToolTip() { Header = "E-Mail", Content = "Send rendered report as mail attachment" }
           };
   
           toolbarSettings.CustomItems.Add(customItem);
           ViewBag.toolbarSettings = toolbarSettings;
           return View();
       }

4. You can use the following codes to set an toolbar-settings property at client side.

       <bold-report-viewer id="viewer" report-service-url="/api/ReportViewer" processing-mode="Remote" toolbar-settings="ViewBag.toolbarSettings">
       </bold-report-viewer>

5. You can use the following codes to create an tool-bar-item-click event at client side.

       <bold-report-viewer id="viewer" report-service-url="/api/ReportViewer" processing-mode="Remote" tool-bar-item-click="onToolBarItemClick">
       </bold-report-viewer>
   
       <script type="text/javascript">
           function onToolBarItemClick(args) {
               alert('Action Triggered');
           }
       </script>

6. You can use the following codes to get toolbar-settings properties on a dynamic object using ViewBag.toolbarSettings and invoke custom actions.

       <bold-report-viewer id="viewer" report-service-url="/api/ReportViewer" processing-mode="Remote" toolbar-settings="ViewBag.toolbarSettings" tool-bar-item-click="onToolBarItemClick">
       </bold-report-viewer>
   
       <script type="text/javascript">
           function onToolBarItemClick(args) {
               if (args.value == "E-Mail") {
                   alert('Action Triggered');
               }
           }
       </script>

Create custom email action

1. Create a new action method SendEmail in the Web API service.

2. Export the report to the required type using the ReportHelper.GetReport method to send a report stream as an attachment.

3. The following code sample exports the report to stream and send it as an attachment to a specified mail address. In the code, the SmtpClient method is used to send the report as an email attachment.

       public object SendEmail([FromBody] Dictionary<string, object> jsonResult)
       {
           string _token = jsonResult["reportViewerToken"].ToString();
           var stream = ReportHelper.GetReport(_token, jsonResult["exportType"].ToString(), this, _cache);
           stream.Position = 0;
   
           if (!ComposeEmail(stream, jsonResult["reportName"].ToString()))
           {
               return "Mail not sent !!!";
           }
   
           return "Mail Sent !!!";
       }
   
       public bool ComposeEmail(Stream stream, string reportName)
       {
           try
           {
               MailMessage mail = new MailMessage();
               SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
               mail.IsBodyHtml = true;
               mail.From = new MailAddress("xx@gmail.com");
               mail.To.Add("xx@gmail.com");
               mail.Subject = "Report Name : " + reportName;
               stream.Position = 0;
   
               if (stream != null)
               {
                   ContentType ct = new ContentType();
                   ct.Name = reportName + DateTime.Now.ToString() + ".pdf";
                   System.Net.Mail.Attachment attachment = new System.Net.Mail.Attachment(stream, ct);
                   mail.Attachments.Add(attachment);
               }
   
               SmtpServer.Port = 587;
               SmtpServer.Credentials = new System.Net.NetworkCredential("xx@gmail.com", "xx");
               SmtpServer.EnableSsl = true;
               SmtpServer.Send(mail);
   
               return true;
           }
           catch (Exception ex)
           {
               throw ex;
           }
   
           return false;
       }

   In the above code sample, the report is exported to PDF format and send to users using the SmptClient method.
