DataGridCellsPanel.OnIsItemsHostChanged Method (Boolean, Boolean)
Indicates that the IsItemsHost property value has changed.
Assembly: PresentationFramework (in PresentationFramework.dll)
Notes to Inheritors:
You can override this method and use it as a notification that the IsItemsHost property has changed. Then perform your own logic based on the old and new values. Be sure to call the base class’s method; otherwise, important functionality will be disabled. The base implementation synchronizes the DataGridCellsPanel with the DataGridCellsPresenter or DataGridColumnHeadersPresenter that it is associated with.
