ColumnHeader.Dispose Method (Boolean)
This member overrides Component.Dispose(Boolean), and more complete documentation might be available in that topic.
Disposes of the resources (other than memory) used by the ColumnHeader.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Call Dispose when you are finished using the ColumnHeader. The Dispose method leaves the ColumnHeader in an unusable state. After calling Dispose, you must release all references to the ColumnHeader so the memory it was occupying can be reclaimed by garbage collection.
