How to make a property readonly dynamically in code

Hello,

The answer to your first question largely depends on how you are using the PropertyGrid. Are you using PropertyGrid.SelectedObject(s), PropertyGrid.Properties, or PropertyGrid.Items/ItemsSource to populate the control? Are you using a custom data factory or data accessors?

Assuming you are using SelectObject(s), then this thread discusses how the IsReadOnly property can be hooked up so it can be changed during runtime:

For your second question, the PropertyGrid has support for "filtering" using the DataFilter property. There is a QuickStart in our Sample Browser that shows this in action.

Alternatively, you could create a custom PropertyDataAccessor (like above for read-only) that has a IsVisible property and hook that up to the PropertyGridDataAccessorItem.
