As suggested in a past thread I have tried adding a third column to a property grid in order to place a button there with custom functionality. I was puzzled to discover that all property grids appear to somehow share Columns property. To be certain this has nothing to do with my app, I have created a sample reproducing this issue. Please find code/XAML below. The app creates two grids side by side bound to two different Rects. Button click adds a single column to the left grid and the other grid is also affected in the same way.
Is this really by design? And if so, why and how can one add a column to a particular property grid? Thanks!
