Editing arrays in PropertyGrid

[Guest]

Is there any way to prevent a PropertyGrid from allowing the user to expand
the elements of an array? For properties that are of type ArrayList or
CollectionBase a PropertyGrid only allows the items to be edited in the
Collection Editor (by clicking the button with the ellipses). But, for
properties of type Array a PropertyGrid also allows array elements to be
edited directly by expanding the array within the PropertyGrid. The problem
is that (as far as I know) no events are raised when the value of an element
is changed directly in the PropertyGrid, but I need to know whenever an array
(or any of its elements) change so that I can update my application.

Thanks for any help.

Hi Lance,

Thanks for your posting!

The expanded behavior for Array type property is achieved through
ExpandableObjectConverter class, and Array class is defaultly assiciated
with this class, so it will default expand itself in PropertyGrid.

Based on my understanding, you want to be notified when a child item of the
array is modified in PropertyGrid.

Currently, we may use propertygrid's PropertyValueChanged event to
intercept the property modify operation. Hope this helps.
