Server Error: Specified cast is not valid?

[User (Legacy)]

I have the following code after I have installed the stats extension. This 

is copied straight from the docs and put into a simple .aspx page. However I 

get the error at the bottom of the page....

You are using the wrong statiscal component, you have:

new SoftwareFX.ChartFX.Statistical.WinForms

This is the Windows Form version, you are using the Chart FX Web Forms 

component you must do:

new SoftwareFX.ChartFX.Statistical.Server

-- 

FP

Another question so I don't bog down this newsgroup. The documentation shows 

View C# Code, and also an aspx icon that when clicked shows what I assumed 

to be .aspx code. If I put this in a .aspx file I got that error from 

before. Is there anywhere on your site on in the docs that go over the API 

with samples for developing applications with C# on .aspx pages for the 

stats, I have bought the full version and am completely confused as to how 

to use it....
