Using PDFViewer after version 19.3.0.43

Question

I have this code but the pdf stopped being displayed after version 19.3.0.43, until it all worked, did something change in 19.3.0.44?

@inject IConfiguration Configuration

<SfPdfViewer Width="100%" Height="100%" @ref="@PDF" DocumentPath=@DocumentPath

ServiceUrl=@Configuration["PdfUrl"]></SfPdfViewer>

@code{

//PARAMETROS

[Parameter]

public string ReportPath { get; set; } = "";

public byte[] byteArray { get; set; } = new byte[0];

public string base64String { get; set; } = "";

public string DocumentPath { get; set; } = "";

private SfPdfViewer PDF = new SfPdfViewer();

protected override void OnInitialized()

{

if(!string.IsNullOrEmpty(ReportPath))

{

byteArray = System.IO.File.ReadAllBytes(ReportPath);

base64String = Convert.ToBase64String(byteArray);

DocumentPath = "data:application/pdf;base64," + ReportPath;

}

Hi Fernando, Kindly use individual Syncfusion NuGet packages for
your components. We don’t have support to use Syncfusion.Blazor package along
with Syncfusion.Blazor.PdfViewerServer.Windows. Regards,Visvesvar K V

Hi Fernando,We were unable to reproduce the reported issue in the
latest NuGet package(v20.3.0.47). Kindly upgrade the NuGet package and the
script version to the latest version to get the reported issue resolved. These
versions must be the same. Kindly try upgrading and get back to us if the issue
still exists.Package:Blazor Client : https://www.nuget.org/packages/Syncfusion.Blazor.PdfViewer/Blazor Sever: https://www.nuget.org/packages/Syncfusion.Blazor.PdfViewerServer.Windows

I set up the example, it stops loading the component itself and gives an error in the latest version, in version 19.3.0.43 it can open normally. Just update the Nuget package version and see the difference in execution.

Click on the PDF menu.

If I leave only the Windows package of the PDF it works, but as I need it in another project with other components it shows an error "The call is ambiguous between the following methods or properties" in Program.cs

Removing the Nuget package and leaving only the PDF one works but doesn't solve my project.

Hi Fernando,Kindly use Syncfusion.Blazor.PdfViewer project
instead of Syncfusion.Blazor project and then you can add each single component
package to your project. This will resolve your issue. Kindly try as we mentioned.If You still face any issues Kindly revert to
us.Regards,Visvesvar K V

I tested it worked but I need there is an error in the SfPdfViewer, the SfPdfViewerServer works normally, follows an example project which does not open the PDF and breaks the navigation, it gives an error who interrupts the navigation.

The project is ServerApp in WebAssembly seems to work normally.

Hi Fernando,

Kindly use Syncfusion.Blazor.pdfviewerserver.windows instead of syncfusion.blazor for Wasm project and use <SfPdfViewerServer> tag for it.

We have also referred to the script in Layout. cs HTML file.

We have also added dependency on imports. Razor -

@using Syncfusion.Blazor.PdfViewerServer

We have also shared the modified sample.

Kindly find the sample - https://www.syncfusion.com/downloads/support/directtrac/general/ze/PDFViewerSample_913a970e1288957794.zip

Good Morning.I understand how both components work, but I have an application where the syncfusion.blazor package was used, this application has several other components that we developed that use syncfusion.blazor, if I use synfucion.blazor.pdfviewerserver.windows I will have a problem of ambiguity and I will have to remove the entire syncfusion.blazor package from everything and use the segmented syncfusion packages. in the syncfusion documentation it is indicating that the syncfusion.blazor package for both serverside, by webassembly, as I sent in the syncb application example itself. from the syncfusion.pdfviewerserver.* package works in both webassembly and serverside.We have a scheduled change in our application where we will remove syncfusion.blazor from everything and switch to the syncfusion.blazor.* packages but our application does not do this at this time.Do you understand my problem?
