Hello,

I have Manual CRUD for Parent and Child bands and separate adding/updating/deleting events for parent and child bands. I am not using "Enable Inheritance = True" on parent because I have different dropdowneditors in parent and child bands. Please look at the markup below.

Issue: Everything works fine, but when I add a new row in the child band, the new row is not shown immediately after the postback. However, if I refresh the page and expand the parent row again, I see the new row added to the child band. 

I am binding the grid in page_load and also in page_prerender events. Please help.
