FolderList,

Mail,

Calander,

Contact,

Task,

Search

}

public partial class Form1 : Form

SelectedPanelForTreeView ObjSelectedPanelForTreeView = SelectedPanelForTreeView.FolderList;

[Category("Choose Default TreeView Panel")]

[Browsable(true)]

[Description("Select the panel to show default selected under treeview by default FolderList is selected ")]

public SelectedPanelForTreeView DefaultSelectedPanel

{

get { return ObjSelectedPanelForTreeView; }
