Busy Indicator while waiting for print dialog

[Jared Pinchot]

Is it possible to pop up a busy indicator while waiting for the print dialog to show up in the Silverlight Report Viewer. This is an issue with larger reports that take a while to render since users have no real indication that the application is doing anything. We get an indicator when you select one of the export options (i.e pdf export).

Hello Jared,

Thank you for the suggestion. There is no way to achieve this in the current version, but we would definitely have it in mind when working on subsequent versions of the product and improving the Silverlight viewer.

Best wishes,

Hi, Steve.

Any news about it?   A 145 page report needs about 2 minutes until the adobe print dialog shows up (I must use adobe).   I want to show a busy indicator but I don't know when to hide it.


Regards,


Iosu.

Hello Iosu,

We have not had time to work on this user experience improvement, but we have plans to improve the Web Report Viewer as a whole and would definitely have this suggestion in mind.
For the time being you can achieve this functionality by replacing the original OnPrint and OnPrintReportLoaded functions of the client-side viewer object. Here is a sample code which illustrates the approach:

Copy Code

<telerik:ReportViewer runat="server" id="ReportViewer1" Height="570px"
            Width="780px"></telerik:ReportViewer>
        <asp:Label runat="server" ID="Label1"></asp:Label>
         <script type="text/javascript">
            var viewer1 = <%= ReportViewer1.ClientID %>;
            viewer1.OnPrintReportLoadedOriginal = viewer1.OnPrintReportLoaded;

            viewer1.OnPrint = function()
            {
                UpdateStatusLabel("Preparing the report to print....");
                this.PrintReport();
            };

            viewer1.OnPrintReportLoaded = function()
            {
                viewer1.OnPrintReportLoadedOriginal();
                UpdateStatusLabel("");
            }

            function UpdateStatusLabel(msg)
            {
                var label = document.getElementById('<%=Label1.ClientID %>');
                label.innerHTML = msg;
            }

         </script>

Further you can customize the script to show or hide an animated image or implement any other way of displaying the print progress. Hope it helps.
