Printing using ReportViewer in Chrome and Firefox

asp.netprintingreportviewer

I have ASP.NET Webforms which is using ReportViewer control to print reports (LocalReport) and, since direct printing is not working in Chrome and Firefox, i need to add button which will somehow do it in Chrome and Firefox. Any ideas?

I had the same issue once and found that explicitly specifying what controls in the ReportViewer control should be shown did the trick. I also added a ScriptManager to the page. The code below works in FireFox & Chrome. Also, the ReportViewer control has issues with other browsers when used in conjunction with UpdatePanels. Depending on how your markup is setup, these might be your issues.

    <rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt"
        InteractiveDeviceInfos="(Collection)" ProcessingMode="Remote" WaitMessageFont-Names="Verdana"
        WaitMessageFont-Size="14pt" ShowExportControls="true" Width="1280px" Height="700px"
        ShowBackButton="true" ShowToolBar="true" ShowParameterPrompts="true" ShowPageNavigationControls="true"
        ZoomMode="Percent" ZoomPercent="100" ShowReportBody="true" InternalBorderStyle="Solid">
    </rsweb:ReportViewer>

Some issues such as ActiveX occur with older versions of the reporting controls. You can find out which version by looking in the web.config file. Version 8 and lower have this issue.

    <add assembly="Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
    <add assembly="Microsoft.ReportViewer.Common, Version=10.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />

ReportViewer Control – Height issue

This is the way I fixed, take a look

<div style="Width:auto;"> 
<form id="form1" runat="server" style="width:100%; height:100%;">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <rsweb:ReportViewer ID="rptViewer" runat="server" Width="100%" Height="100%" AsyncRendering="False" SizeToReportContent="True">
    </rsweb:ReportViewer>
</form></div>

The thing doing the magic is AsyncRendering="False" SizeToReportContent="True" the rest is basic HTML. The report will be displayed as it was designed.

There might be some code extra, but see if it works for you.

Hope it helps

Google-chrome – ASP.NET ReportViewer Google Chrome CPU usage

The solution is actually some of the ReportViewer JavaScript causes an infinite loop in Chrome, I am posting the source code on how to solve this issue by making a custom version of the ReportViewer control and fixing the broken JavaScript (I've lost the link to the solution, but I didn't write this, just used it :))

I can confirm that now we have upgraded to the newest ReportViewer in Visual Studio 2010, the Chrome CPU issue no longer exists and this work around isn't required.

public class MyReportViewer : Microsoft.Reporting.WebForms.ReportViewer
{
    protected override void Render(HtmlTextWriter writer)
    {
        using (StringWriter sw = new StringWriter())
        {
            HtmlTextWriter tmpWriter = new HtmlTextWriter(sw);
            base.Render(tmpWriter);
            string val = sw.ToString();
            val = val.Replace(@"!= 'javascript:\'\''", @"!= 'javascript:\'\'' && false");
            writer.Write(val);
        }
    }
}
