Saving report parameters for users

[Gregory Kohle]

Hi,

I have the Report Viewer embedded in an MVC application.

Now I wonder if there is any way for me to save the report parameters a user selects, so that, when he opens the report page the next time, the parameters are already preset.

Hi Manuel, 

Thanks for contacting Syncfusion support. 

We can get the parameter value specified in the report using “_viewReportParamsClick” prototype method, then store the value in the session storage and set the default value when loading again the specific report in ReportViewer as shown in below code example, 

<script> 

            ej.ReportViewer.prototype._viewReportParamsClick = function (event) { 

                var proxy = $('#reportViewer').data('ejReportViewer');                

                proxy._showloadingIndicator(true); 

                

                var parameters = event.data.params; 

                var reportParams = proxy._getParameterJson(parameters, true); 

                if (reportParams) { 

                    sessionStorage.setItem(reportParams[0].Name, reportParams[0].Values[0]); 

                    proxy._viewReportEnableDisable(true); 

                    proxy._refresh = true; 

                    $('#' + proxy._id + '_viewBlockContainer .e-reportviewer-viewerblockcontent table:first').attr('data-isviewclick', 'true'); 

                    proxy._onViewReportClick(reportParams); 

                    proxy.doAjaxPost("POST", proxy._actionUrl, JSON.stringify({ 'reportAction': proxy._reportAction.setParameters, 'parameters': reportParams }), "_setParameters"); 

                } 

                else { 

                    proxy._showloadingIndicator(false); 

                } 

            } 

 

        </script>        

     

We have prepared a sample to get the values specified in the Report and it can be downloaded from below location,

Please refer to the below UG documentation to specify the default value for the Report
