[CLOSED] Chart examples data bind

[speedstepmem4]

Hello,


We are trying to add the chart in our application, but most of the examples data fill from following functions

<%# Ext.Net.Examples.ChartData.GenerateData() %>

where can we find this?

Hi @speedstepmem4,

Please use:

using System;
using System.Collections.Generic;
using System.Globalization;

            set;
        }

Hi Daniil,


Thanks for the reply.


Can you please provide a independent source code which includes .aspx page that help us to have a look on the entire working of Chart?
We used your sample code and ended up with some compilation errors.

Hope you help us!!

Please clarify what exactly compilation errors.

A standalone .aspx page? Well, it should be possible, but it will require modification of the .aspx page that you copy from Examples Explorers. You'll need to modify it each time. Really, it would be simpler to put that GenerateData code into an individual .cs file and get it compiled. Then you'll be able to just copy, paste and run the Chart examples without any changes.
