Currently a single instance of the WPF Report Viewer will often use multiple different HttpClient instances to talk to the Report Server.  This means that cookies added as part of earlier requests may not be sent in later requests.  If the Report Server is behind a load balancer that uses cookies to implement 'sticky sessions', this loose behavior with cookies will cause requests to get routed to different servers which is not ideal.  It is possible to use a storage mechanism on the server that natively supports a web farm (such as the Redis storage option) but that can be tricky to set up.  

Instead, if the report viewer were to re-use the same HttpClient instance for all requests (including initial render request, export requests, print requests, etc.), the load balancer could work to route all requests to the same web server and then any storage mechanism (such as the simple File storage option) would work.

This issue was reported back in 2017 and I'm running into the problem again in 2022.  See: https://www.telerik.com/forums/wpf-reportviewer-cookie-behavior

Exporting a report from the Report-Viewer to Word(docx), then opened in Word for Web (browser-version of Word) causes incorrect rendering of the document. Images are replaced with placeholders.

In comparison, exporting the report as PDF, then opening and converting it to Word and uploading it, renders much more correct and with images.

Hi

If I run the angular report viewer within my main page, all is well. However if the report viewer is hosted in a <p-dialog> (or <p-overlaypanel>), the report does not render (even though data is loaded and the report can be exported). To confirm this, I even have the report visible in a <tr-viewer> on the main page behind the dialog and load them at the same time.

If the dialog is not visible when the main page opens, then the report viewer toolbar is in a column on the left, and is not operational. (see attached)

If the dialog is visible when the main page opens, then the toolbar appears at the top and functions normally. (see attached)

<tr-viewer #rptViewerBody
     [containerStyle]="viewerContainerStyle"
     [serviceUrl]="reportServerUrl"
     [viewMode]="'INTERACTIVE'"
     [scaleMode]="'SPECIFIC'"
     [scale]="1.0">
</tr-viewer>

vs

<p-dialog modal="true"
          appendTo="body" 
          header="Report"
          [(visible)]="showReport"
          [width]="1500" 
          [height]="1500">

        <tr-viewer #rptViewerDialog
            [containerStyle]="viewerContainerStyle"
            [serviceUrl]="reportServerUrl"
            [viewMode]="'INTERACTIVE'"
            [scaleMode]="'SPECIFIC'"
            [scale]="1.0">
        </tr-viewer>
</p-dialog>

In the code, I tried both of these container styles. The result for the dialog was that relative position rendered the toolbar (top or left), but absolute position rendered nothing at all (height became 0)

this.viewerContainerStyle = {
      position: 'absolute',
      top: '0px',
      left: '0px',
      right: '0px',
      bottom: '0px',
      ['font-family']: 'ms sans serif'
    };
this.viewerContainerStyle = {
      position: 'relative',
      width: '1300px',
      height: '1300px',
      ['font-family']: 'ms sans serif'
};

Thanks.

Hi,

There is an issue where the search window that opens from the Report Viewer tool bar does not allow for deleting text from the search string input box using backspace.

The keyboard command provider seems to have many other keys covered for the intended behavior, but backspace does not seem to be handled appropriately.

In my report, I use font SimSun to display Chinese, when preview it's OK, but after click print, an exception is thrown.

Internal Server Error
Font data for font "SimSun" cannot be obtained. Possible reasons are: The font is not installed in . The font is not found in the directories specified by the "FontLocations" configuration entries. The font is not declared in "" configuration section

In my docker image, run command -list, is there.

In CSharp.ReportExamples.VS2017, I copy all reports into project CSharpAspNetCoreDemo, and make them always copy.

Then I change ReportsController to the Reports directory above.

When Run it in IIS, it's OK, but when check into Docker, there is an exception thrown.

 Using Roboto Medium changes values  "FVS!dBTI"  should be "EUR Cash" (shift characters by 1) weird !!!!

So there is an Angular report viewer of sorts, but the report viewer web api component doesn't work with .net core (must target 4.6.1) and the angular component doesn't work with universal/server side rendering.  It would be great if this could get fixed!
