I think JavaScript can be dangerous. Does TreeGrid contain any security issue or risk?
TreeGrid does not contain any security issue. TreeGrid never uses any problematic or forbidden objects like FileSystem. TreeGrid never access other pages then those you filled in input XML. TreeGrid never shows any links to other pages than you filled in input XML. The only exception is link to www.treegrid.com on bottom toolbar, but this link can be hidden in purchased version. Of course, you cannot use in JavaScript any authorization or password validation. These inputs can be filled to and sent by TreeGrid, but always must be validated on server. All TreeGrid code is written by our company, therefore we guarantee, that it does not contain any problematic code. Remember, JavaScript code can be dangerous only if you use some unnamed code from unofficial web sites. The JavaScript code can present security risk only if it is written with intention to do this. And TreeGrid as official commercial product never does such things.
