ASP.NET Webforms

Forgive me for being a newbie. I am looking for a layout framework I can use like this to work with an ASP.NET Webforms app. Before I spend hours trying to shove a gridvew into a pane, I thought I would make sure that it is possible. I am relatively capable on ASP.NET but a newbie to anything javascript. I am currently using very basic methods in ASP.NET like creating a SQLDataSource, using it to populate a DataSet, and then dislplaying certain columns from that dataset, applying filtering, and then of course a details view of any given selection. I am curious to know if I use the data grid object supplied by this library is it as secure as using .Nets framework? Or, am I simply using the .Net framework as described above to fill my DataSet and then using the Dataset as the source for the Webix grid? Again, please forgive the newbie…

The library is fully client side. So all operations with database will be done by .Net code, the library will only show data ( it can filter, sort, group data on client side )

Basically this is the front-end library, it load data from any json|xml feed, that requires .Net code that takes data from DB and generates data feed.
