Custom parameters

[Amjad Khan]

Hello,

I am using 

<SfPdfViewer ServiceUrl="/PdfViewer" DocumentPath="Blazor_Succinctly.pdf" Height="900px">

</SfPdfViewer>

as above. 

I want to know how to pass a custom parameter such as a string when the controller method is called to load this file?

Regards,

Amjad.

Hi Amjad, 

 

Thank you for contacting Syncfusion support. 

 

In our PDF Viewer, there is no direct support to pass the parameter to the server in the blazor platform. However, you can achieve this as a workaround to pass the parameter from client to server using the below code snippet. We have shared the sample for your reference, please refer to the below link. 

 

Code Snippet in the client-side: 

 

<SfPdfViewer @ref="PdfViewer" ServiceUrl=http://localhost:55767/pdfviewer/parameter  DocumentPath="@DocumentPath"> 

</SfPdfViewer> 

 

 

Code Snippet in the server side: 

 

app.UseMvc(routes =>  

            {  

                routes.MapRoute("default", "{controller}/{id?}/{action}");  

            });   

 

 

public IActionResult Load(string id, [FromBody] Dictionary<string, string> jsonObject){  

}

Our application is using Endpoint Routing already in various controllers. So when I put your code snippet on the server side, it gives me this error:

"Using UseMvc to congifure MVC is not supported while using Endpoint routing. To continue using UseMvc, please set 'MvcOptions.EnableEndpointRouting=false' inside 'ConfigureServices'"

I think I need a sample app that works with the default Blazor Webassembly hosted app.

Thanks,

Amjad.
