I have managed to get the searching to work with our existing systems however i have noticed that if items with the same "Value" are returned at different levels. For example, if i am looking for people by their username/name so if i have a person named "sysadmin" who is also part of a group called "Administrators" they are returned at two different levels within the tree and selecting both of them results in the selection appearing multiple times within the textbox. Is there some way that i can link these two (or more) items?
The other problem i am having is that when data is fetched from the server, we also provide an indicator that there are more matched results that are not returned in the search (because we are only displaying the first 20). The total number of matched results is returned as part of the response.
/* 20 items */
In our other dropdownlist selectors we use virtual scrolling to continuously fetch more results and in our grid and list view pages we use paging.
Is there some way that i can indicate to a user that there are more items that could have been returned but weren't? Either by including some sort of paging functionality or appending an indicator of some kind to the item list.
