SupportsNewObjectCreation property doesn't do anything. about blackpearl HOT 3 CLOSED

Hi Sekulicb,

I tried to reproduce scenario issue with steps you mentioned.
I figured there are two separate issue here-

1) Crash on clearing all items -
Are you getting serialization error in exception? If so, try making entity public. i.e. TestData

2) Property throwing exception -
This is highly not recommended doing so. Try creating new property which does not throw exception or wrapper object. However, if you don't control that entity (Third Party) or don't want to create wrapper one, handle property exception in Look-up contract. I was able to do so. Should work for you as well.

One suggestion, implement LookUpContract only if you need custom sorting or want to support new object creation on UI. Basic, filtering is by default provided by control on DisplayMemberPath.

Let me know if this helps!

Hi @nilayjoshi89

1. No, sorry my bad, I forgot to include the public keyword at the beginning. Entity is public
2. I actually considered creating wrapper object, and I think it should be a way to go. Catching exception for each object will not be performant, since ItemSource will contain right from the start ~4500 items.

Yes, "starts with" query will not work for me. I need to match cases not just check if the string starts with given input. I need to check if substring is found in string. So for example:

user starts typing "lay"

it will find the nilay as search result instead of typing "ni...." to get the same result.

Closing issue as all points are addressed.
