FileManager sample code not compiling

[Saravanan Arumugam]

I downloaded the sample code of FileManager Blazor component (FileManager-806090727) and while trying to run that I get the below build error. Kindly suggest what could be wrong.

MSB3073 The command "dotnet "C:\Users\username\.nuget\packages\microsoft.aspnetcore.blazor.build\3.0.0-preview9.19465.2\targets\../tools/Microsoft.AspNetCore.Blazor.Build.dll" write-boot-json "obj\Debug\netstandard2.0\FileManager.Client.dll" --references "D:\Samples\FileManager-806090727\FileManager\Client\obj\Debug\netstandard2.0\blazor\bootjson-references.txt" --embedded-resources "D:\Samples\FileManager-806090727\FileManager\Client\obj\Debug\netstandard2.0\blazor\embedded.resources.txt" --linker-enabled --output "D:\Samples\FileManager-806090727\FileManager\Client\obj\Debug\netstandard2.0\blazor\blazor.boot.json"" exited with code -2147450730.

Hi Shameer,

Thanks for the reply, The sample application zip file you had given the link is not of File manager, it is of Side bar and Weather forecast. I tried even the restore actions and it didn't help. Kindly attached the sample working code of File manager Server and Client applications.

Thank you.

Hi Shameer,

Let me explain few more details on what I am trying to achieve. I have a Blazor Server application with Controllers and Pages. From one of the pages I want to show the files in Azure blob using SF's File manager. To begin with, I added <EjsFileManager> component, getting data from https://ej2services.syncfusion.com/production/web-services/api/FileManager/FileOperations. This shows the content in File manager. When I change this point to one of my controllers (FM/FilesProvider/Files), I get the below error.

     NetworkError: Failed to send on XMLHTTPRequest: Failed to load /FM/FilesProvider/Files

Given below other details:

Dotnet SDK version: .NET Core 3.1

EJ2 Version: Syncfusion.EJ2.Blazor - Version="17.3.0.19-beta

     Syncfusion.EJ2.FileManager.AzureFileProvider.AspNet.Core - Version="17.3.0.14"

Visual Studio version: VS Professional 2019 Preview (16.3.0 - Preview 3)

Thank you.

Hi Saravanan,

 

Based on your provided details, we understood that you are trying to use ej2-azure-file-provider service for loading your azure blob storage files in EJ2 File Manager. For your convenience, we have prepared an server-side blazor application with File Manager and used the azure file provider service to load file system in the File Manager.

 

Please, download the sample from the below link.

 

Sample: https://www.syncfusion.com/downloads/support/forum/148583/ze/Server-side-blazor-filemanager580481986

 

Note: In Sever side Application, the controller part is not detected. Ensure the below code is available in your startup.cs or else you can add it. 

 

public void ConfigureServices(IServiceCollection services) 

        {                                   

            services.AddCors(c => 

            { 

                c.AddPolicy("AllowOrigin", options => options.AllowAnyOrigin()); 

            }); 

        } 

public void Configure(IApplicationBuilder app, IWebHostEnvironment env) 

        { 

            app.UseCors(options => options.AllowAnyOrigin()); 

            app.UseEndpoints(endpoints => 

            { 

              //Map the controller part 

              endpoints.MapControllers(); 

                endpoints.MapBlazorHub(); 

                endpoints.MapFallbackToPage("/_Host"); 

            }); 

        } 

 

 

In the attached sample, just register your account details and proper blob path details to successfully access your azure blob storage and load the files into the File Manager. For security reasons we have not provided any azure account details in the sample, instead we have commented with precise description which will help you to register your azure account details in the application.

 

Please, let us know if you need any further assistance.
