Blazor: Unable to add new item to Grid

Hi @RobertMcLaws,

This all sounds as this issue. Try the following:

var entity = new Entity();
Entities.Insert(0, entity);

Entities = Entities.ToList(); // Update the reference so the DataGrid refreshes its cache

grid.EditRow(entity);
StateHasChanged();

We will add built-in insert support in one of the next releases.
