Examples
The following code example demonstrates how to create a DesignerActionItemCollection and populate it to form a smart tag list. This code example is part of a larger example provided for the DesignerActionItem class.
Public Overrides Function GetSortedActionItems() _
As DesignerActionItemCollection
Dim items As New DesignerActionItemCollection()
'Define static section header entries.
items.Add(New DesignerActionHeaderItem("Appearance"))
items.Add(New DesignerActionHeaderItem("Information"))
'Boolean property for locking color selections.
items.Add(New DesignerActionPropertyItem( _
"LockColors", _
"Lock Colors", _
"Appearance", _
"Locks the color properties."))
If Not LockColors Then
items.Add( _
New DesignerActionPropertyItem( _
"BackColor", _
"Back Color", _
"Appearance", _
"Selects the background color."))
items.Add( _
New DesignerActionPropertyItem( _
"ForeColor", _
"Fore Color", _
"Appearance", _
"Selects the foreground color."))
'This next method item is also added to the context menu
' (as a designer verb).
items.Add( _
New DesignerActionMethodItem( _
Me, _
"InvertColors", _
"Invert Colors", _
"Appearance", _
"Inverts the fore and background colors.", _
True))
End If
items.Add( _
New DesignerActionPropertyItem( _
"Text", _
"Text String", _
"Appearance", _
"Sets the display text."))
'Create entries for static Information section.
Dim location As New StringBuilder("Location: ")
location.Append(colLabel.Location)
Dim size As New StringBuilder("Size: ")
size.Append(colLabel.Size)
items.Add( _
New DesignerActionTextItem( _
location.ToString(), _
"Information"))
items.Add( _
