RadSpreadStreamProcessing - classes inaccessible

[Dean]

Hi,

I'm sure I'm being stupid but could anyone help with why the following classes are inaccessible when I try to follow the example at https://www.telerik.com/blazor-ui/documentation/knowledge-base/grid-custom-cell-formatting-with-radspreadstreamprocessing#custom-cell-formatting-of-the-exported-file-with-radspreadstreamprocessing ?

It's not like they are completely unrecognised, just inaccessible due to their protection level.

What am I missing?

Thanks,

Dean

Hi Dean,

All these are public, so this is either some Visual Studio bug (try restarting it), or something is misconfigured in the app itself. Try the example from our documentation in a brand new empty app and then compare the two apps.

Is there a minimum version of Telerik.Documents.SpreadsheetStreaming I need?  I'm only on 2022.2.428.

Each Telerik UI for Blazor version requires a specific version of Telerik Document Processing:

I get the same behaviour in a brand new empty app - see attached

@Dean - thanks for the app. I dug deeper and it turned out that the KB example is using Telerik Document Processing features, which are not available for your version 2022.2.428.

The situation is:

• .NET 8 is supported by Telerik UI for Blazor 5.x. I recommend at least 5.1.1, which requires Telerik Document Processing 2024.1.124. If I use these two versions, then the app builds and runs fine.
• If you must use older Telerik product versions, then you can go with .NET 6 + Telerik UI for Blazor 3.6.1 + Telerik Document Processing 2022.3.906 . This is the oldest DPL version that can integrate with the code in the discussed KB without compilation errors.

Ok, I can actually use 2022.3.906 with Telerik UI for Blazor 3.3.0, and this fixes the problem and doesn't appear to have broken anything else.  Thanks.
