Printer.Print() and PrintDialog() methods not found

[dim7pro]

Hello,

I'm trying to call the Print() and PrintDialog() methods for a chart when user presses a button outside the chart.

My code: test.aspx.cs

using ChartFX.WebForms;

protected void btnPrint_Click(object sender, EventArgs e)

{

ChartPower.Printer.Print(); 

}

But VS2008 shows me, that these methods are not available.

The error: 'ChartFX.WebForms.Printer' does not contain a definition for 'Print' and no extension method 'Print' accepting a first argument of type 'ChartFX.WebForms.Printer' could be found.....

I've done the same steps described in Programmer's Guide & Sample. What have I done wrong? 

Thank you,

Best regards,
