We have a treegrid object, which sometimes can have over couple hundreds even 1000 files on the list. We have dragandrop enabled and have smartrending enabled, not smartxmlParsing though.
Problem is when user sometimes needs to select mass of files by holding shift key. Then we found out, if user jump to the page which hasn’t been rendered yet, shift-select simply wouldn’t work. Be able to select all the files on the list, user needs to scroll whole list of files, then do multi-select, even then, seems there is maximum selection limitation (which is around 300).
Is this known issue? Or we can do different thing to avoid it to make multi-selecting working better?
