'Declaration Protected Overridable Sub OnSelectedItemsChanging( _ ByVal args As SelectedItemsChangingEventArgs _ )
protected virtual void OnSelectedItemsChanging( SelectedItemsChangingEventArgs args )
Three types of items can be selected, Records, Cells and Fields. This functionality is controlled by the following properties:
The SelectedItems object exposes 3 collections (DataPresenterBase.SelectedItemHolder.Records, DataPresenterBase.SelectedItemHolder.Cells and DataPresenterBase.SelectedItemHolder.Fields) that can can be used to select/de-select specific items. In addition, selection can be affected by setting the Record's Record.IsSelected, the Cell's Cell.IsSelected and the Field's Field.IsSelected properties.
The following describes how selection behaves in various scenarios:
Note: Record and Cell selection is mutually exclusive. Selecting one or more Records will automatically clear the Cell selection and vice versa.
