This page is enclosed inside a MasterPage.
When I change the value in the dropdownlist happen two strange facts (probably a context to another):
part of the layout is modified and after you run the command to change the content to the chart at the bottom right scroll bar begins to load (do not know what).
I know it will be stupid, but because you are noob asking for help.
Thanks in advance!

Anyone can help me ?

Hi Filippo,

As I was able to see from your picture attached you are using the same code as in our demo - http://demos.telerik.com/aspnet-ajax/chart/examples/appscenarios/dyndata/defaultcs.aspx. However there is no scrollbar ...Could you open a Support thread and send us a sample project where your issue reproduces so that we will be able to investigate it and help you?

All the best,
Evgenia

I thank you greatly for the reply, I solved within the master page because it contained a Jquery that bothered the layout.
Thanks anyway!
