Custom Actions

Add user defined buttons to the toolbar and invoke custom actions using the Report Viewer property. You can create a custom email option to send an email 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, itemType, cssClass, and tooltip. The toolBarItemClick 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. You can use the following codes to create an event with custom action.

        <script type="text/javascript">
            $(function () {
                    reportServiceUrl: "/api/ReportsWebApi",
                    reportPath: '~/App_Data/Sales Order Detail.rdl',
                    toolbarSettings: {
                        showToolbar: true,
                        items: ej.ReportViewer.ToolbarItems.All & ~ej.ReportViewer.ToolbarItems.Print,
                        customItems: [{
                            groupIndex: 1,
                            index: 1,
                            type: 'Default',
                            cssClass: "e-icon e-mail e-reportviewer-icon",
                            id: 'E-Mail',
                            tooltip: {
                                header: 'E-Mail',
                                content: 'Send rendered report as mail attachment'
                    toolBarItemClick: 'ontoolBarItemClick'
            //Toolbar click event handler
            function ontoolBarItemClick(args) {
                if (args.value == "E-Mail") {
                    var proxy = $('#viewer').data('ejReportViewer');
                    var Report = proxy.model.reportPath;
                    var lastsIndex = Report.lastIndexOf("/");
                    var reportName = Report.substring(lastsIndex + 1);
                    var requrl = proxy.model.reportServiceUrl + '/SendEmail';
                    var _json = {
                        exportType: "PDF", reportViewerToken: proxy._reportViewerToken, ReportName: reportName
                        type: "POST",
                        contentType: "application/json; charset=utf-8",
                        url: requrl,
                        data: JSON.stringify(_json),
                        dataType: "json",
                        crossDomain: true

Create custom email action

To create custom email action, follow these steps:

  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. 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(Dictionary<string, object> jsonResult)
            string _token = jsonResult["reportViewerToken"].ToString();
            var stream = ReportHelper.GetReport(_token, jsonResult["exportType"].ToString());
            stream.Position = 0;
            if (!ComposeEmail(stream, jsonResult["reportName"].ToString()))
                return "Mail not sent !!!";
            return "Mail Sent !!!";
        public bool ComposeEmail(Stream stream, string reportName)
                MailMessage mail = new MailMessage();
                SmtpClient SmtpServer = new SmtpClient("");
                mail.IsBodyHtml = true;
                mail.From = new MailAddress("");
                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);
                SmtpServer.Port = 587;
                SmtpServer.Credentials = new System.Net.NetworkCredential("", "xx");
                SmtpServer.EnableSsl = true;
                return true;
            catch (Exception ex)
                return ex.ToString();
            return false;

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

  3. Build and run the application.
