category defined for child objects

Grids for WPF Forum

I have a parent object that contains a collection of child objects.
I am using ExpandableObjectConverter.

When I expand a child object in the parent collection, the child's property items are displayed, but not the categories for the child object. If I displayed the property grid of just an instance of a child object as the selected object the categories of the child are displayed.

Is this the correct behavior?

Thanks,
Mary

Hi Mary,

That is correct. Categories are only currently displayed for root level properties. This behavior mimics how the Visual Studio PropertyGrid works.

I have the same problem. I have a root node in the property grid that defines what properties are available, and all other properties are children of that node. This means that I cannot categorise the properties any longer.

Is there any way to get the sub-properties to be categorised?

Thanks, Sterren

Hi Sterren,

Sorry but expandable categorization can only be done at the root level.  The only way to do sub-property categorization would be to do what it looks like you are already doing, by using ExpandableObjectConverter.

I found a work-around. Effectively, I use one property grid for the derived class selection, and the other is bound to the selected class properties.

Butting them together makes them look like a continuous property grid, except for the help section in between. Is there a way to disable this help section?

Hi Sterren,

Sorry for the late reply.  Yes, you can set IsSummaryVisible = false to hide that portion of the PropertyGrid.
