Demo "paste-from-excel" generates errors

[Stéphane]

Hi,

I downloaded the Telerik UI for Blazor Trial (version 2.25.0) and I'm investigating the "paste-from-excel" demo (first one I have to go through) from GitHub paste-from-excel (.Net 5.0). Unfortunately I get the following runtime errors (see screenshot).

I'm using:

• VS 2019 Enterprise 16.10.2
• Chrome  91.0.4472.124

Does anyone know how to fix it?

I would really appreciate any help because I'm far from saying to upper management that this is the right library for us.

Thanks in advance

Hello Stéphane,

If you are using a Trial version, you must replace the references in the project to the trial names of the Telerik packages (amend ".Trial") to them:

• project ref: https://github.com/telerik/blazor-ui/blob/master/grid/paste-from-excel/PasteFromExcel.csproj#L8 should be 

  <PackageReference Include="Telerik.UI.for.Blazor.Trial" Version="2.25.0" />

• static assets: https://github.com/telerik/blazor-ui/blob/master/grid/paste-from-excel/Pages/_Host.cshtml#L14-L15  should be

      <link rel="stylesheet" href="_content/Telerik.UI.for.Blazor.Trial/css/kendo-theme-default/all.css" />
      <script src="_content/Telerik.UI.for.Blazor.Trial/js/telerik-blazor.js" defer></script>

Those samples generally come with the commercial references as that's their most common audience.

If this does not help, enable the detailed errors here https://github.com/telerik/blazor-ui/blob/master/grid/paste-from-excel/Startup.cs#L30

services.AddServerSideBlazor(opts => opts.DetailedErrors = true);

to see what the actual error is, and see if it is one of those: https://docs.telerik.com/blazor-ui/troubleshooting/js-errors
