Designer broken binding to interface hierarchy
posted

I am trying to bind the grid to a datasource defined as an interface. The interface has one property that is an ienumerable of another interface. When I set the first interface as the datasource for the grid, the designer will not let me set properties for the inner band, as it doesn't show me any of the columns for that band. I have attached a sample project to demonstrate this. Here are some screenshots to illustrate the problem:

1) This shows the grid in the designer with the inner band expanded

2) This shows the columns collection within the grid's custom property editor

 

And finally, here is the grid at runtime, populated with sample data. The inner band is displaying correctly at run time, but without design time access I can't control its appearance:
