Data Grid showing text instead of icon

I have just upgraded to Radzen Blazor version 5.5.2 from version 4.34.4.

The DataGrid headers are showing the text sort/ arrow_drop_up and arrow_drop_down instead of icons. I am trying to figure out what I'm doing wrong.

Thanks

Hi @BillLinck,

Check this thread: Migration to Radzen.Blazor v5.0

Thank you very much for the quick response. That worked.
