Error 7 The type or namespace name
‘SampleMain’ does not exist in the
namespace
‘System.Windows.Forms.DataVisualization.Charting.Utilities’
(are you missing an assembly
reference?)

        System.Windows.Forms.DataVisualization.Charting.Utilities.SampleMain.MainForm mainForm = (System.Windows.Forms.DataVisualization.Charting.Utilities.SampleMain.MainForm)this.ParentForm;

    If you need help figuring out the ‘structure’ of the namespaces, use the Object Browser from within Visual studio or use Reflector to view what’s within the

    System.Windows.Forms.DataVisualization.Charting.Utilities

    namespace. This may help you gain an understanding as to what you can and cannot access within each.
