We have an ASP.Net RadFileExplorer integrated into our system and have noticed that once the number of files increases to 150 or more - suddenly we start getting "callback failed" when the user enters info in the "Filter By" (build-in control shown above the file list view in explorer) . Initially thought this was data related, but after experimentation appears to be a length limit of some type in the transfer, thus once the return size is larger than that limit - we get the error independent of the data - otherwise all works as expected. Strangely when I set a break on the error callback, I do see all the data has been transferred from the server as expected.
Is there a size limit on the return of the webresource call, or other limit ??? any tips on debugging this issue is appreciated.
