Import Wizard - XAF Win and XAF BLAZOR Net Core 6

[AndresVanegasC]

Hi!

I am trying to implement the windows importer in XAF Blazor but I ran into 2 difficulties.

1. I get an error when importing
2. How can I do it in Blazor?

I initially wrote to XAF support but they sent me here, could you please validate the ticket I issued.

This ticket is in the name of Jose Russi.

https://supportcenter.devexpress.com/ticket/details/t1115160/blazor-import-and-export-excel

Error in debug.

ERROR:

Object reference not set to an instance of an object.

There is no Blazor equivalent, however there is an ExcelImporter.Win package that may work better

Hi!

Thank you for your prompt response, we have correctly implemented in WIN what you suggest "ExcelImporter"; but we tried to run in XAFBlazor and encountered the following error when clicking on new.

What can we do there, or are we missing something?

Sample project attached.
TestImportWizard.zip

attached bug
ErrorXafBlazor.txt

here you can download the 2 files, if the previous ones are not functional.

Hello!

Do you have any comments or is there somewhere a step by step or example where I can see how to correctly implement the "ExcelImporter" for Xaf Blazor?

either

Is there nothing we can do to implement it for Xaf Blazor?

Thank you, I am very attentive.

there is no Blazor counterpart

Find-XpandPackage *Excel*

Id                      Version    Source
--                      -------    ------
eXpandExcelImporter.Web 22.1.401.0 Release
eXpandExcelImporter     22.1.401.0 Release
eXpandExcelImporter.Win 22.1.401.0 Release

ti implement it your self you have to look whats on the Win,Web sides and do the same with Blazor.

I also had the same problem as you. Have you solved it yet?

The issue with running in blazor relates to the progressbarviewitem. Since no Progress exists within Devexpress Blazor, it will not run.
