Printing
RadSparkline supports printing out of the box. You can use the Print or the PrintPreview to directly print the contents of the Sparkline control.
Example 1: Use the PrintPreview Method.
private void radButton2_Click(object sender, EventArgs e)
{
radSparkline1.PrintPreview();
}
Private Sub RadButton2_Click(ByVal sender As Object, ByVal e As EventArgs)
radSparkline1.PrintPreview()
End Sub
