Hello all,

I've encountered an undefined behaviour of CollectioEditor with 2014 Q1 and previous.
My data have 2 levels of nesting: Client -> List<Contracts> -> List<Option>.
Also I use custom template for CollectionEditor to set some properties of RadPropertyGrid for editing List<Option> (dimensions + visibilty).

How to reproduce the problem:
1. Use CollectionEditor for "Contracts" and add new Contract twice.
2. Select second Contract.
3. Use CollectionEditor for "Options" and add new Option.
4. Select first Contract
5. Select second Contract
6. Open CollectionEditor for "Options" ... ooops.. no option presents!

Problem occur even if I use original template from assembly.

The test project can be found here.

Best regards,
Zber

Hi Zber,

Thank you for the feedback.

I was able to reproduce the problem you report. However the used approach is not quite recommended and that's why the behavior is wrong. If you would like to override the CollectionEditor template you should apply implicit themes. I updated the project and attached it for a reference. Let me know if you have additional questions.

Hi Yordanka,

Unfortunately implicit themes didn't help me.
For example I'm overriding CollectionEditor template to have NestedProperties visible in internal RadPropertyGrid as Didie recommended here.
What should I do?

I've update the project with CollectionEditorTemplate overriden - link.
