When the user tries to edit a cell in the Grid an exception is thrown. This happens if the Model to which the Grid is bound has an indexer property.

A possible workaround is to map the data to a collection of a different type that has no indexer property: https://blazorrepl.telerik.com/cxaGwcOC383PD8Jr24
