View Full Version : save/load checkbox tree selection

7 Sep 2016, 5:07 PM

i have a checkbox tree with ~40K items (5 level deep) representation of the files on the hdd.

it is very easy to save the selection, you ask the tree/datastore what is the selection and it gives you the data

how can i store that selection and later on load it (people may have added or removed nodes from the tree in the meantime)

currently i go through the tree elements and if it matched my saved info i enable it but that takes a very long time (and browsers hate long operation)

so any idea how to save and load a tree selection the most performant way? (lets say i selected 1K elements from a 40K elements tree)

anyone worked with checkbox tree ? i'm trying to get it working with 50K items and performance is really bad, any suggestion will be highly appreciated.

so how do you make checkbox tree that will display all files on the HDD, think about windows explorer, that works fast when you check on an item?
