Here are my 2 cents as well:
- Today is Saturday.
- The last attached project would run if the TItem attribute of the DataGrid is set.
- One can also use attrbutes to attach event handlers with any parameters if the one generated by Radzen does not provide sufficient context.
@joshbooker making a hierarchical outline designer isn't in our plans. It would require immense amount of work and would make Radzen more complex than it already is - we can't just get rid of the current designer and having two designers is an overkill.
The current design time preview doesn't differ by the runtime too much as we use the runtime output of the Radzen Blazor components.
I am locking this thread now as it went in the wrong direction.
