Method Detail

ClearUltraGridColumnEditors (UltraGrid)
Purpose: Clears references to the UltraGrid cells EditorComponent
Notes: See SCL-2305 for details. Those references seem to be circular references
and cause the grid not to be GC'ed when a Form is closed. Invoked from
the BaseForm:OnFormClosed method

Parameters:
poUltraGrid Infragistics.Win.UltraWinGrid.UltraGrid
The reference to the UltraTree object
Top

ClearUltraTreeNodes (TreeNodesCollection)
Purpose: Deletes nodes objects in a TreeNodes Collections
Notes:

Parameters:
poNodesCollection Infragistics.Win.UltraWinTree.TreeNodesCollection
The reference to the TreeNodesCollection
Top

ClearUltraTreeNodes (UltraTree)
Purpose: Deletes all nodes objects in the UltraTree's Nodes Collection
Notes:

Parameters:
poUltraTree Infragistics.Win.UltraWinTree.UltraTree
The reference to the UltraTree object

DeleteObject (IService)
Purpose: Deletes an Service instance, if valid and not registered
with the Service Container

Top

DeleteObject (IService[])
Purpose: Deletes Service instances from an Array, if valid and not registered
with the Service Container
Notes: We have noticed a potential regression in OE11.4 CQC documented in
SCL-392. It appears that passing an initialized Object[] to this method
raises the runtime error: Uninitialized array used as source of assignment.
(14906). We will investigate the issue in probably have to log a ticket
with PSC when the issue is still present in 11.4 FCS. At this time
we do not recommend to use this method.

poService Ccs.Common.IService
The ABL array of objects to delete

This method is just form completeness to allow a consistent coding

Parameters:
