Remarks

Handle the DxComboBox.SelectedDataItemChanged, DxListBox.SelectedDataItemsChanged, or DxTagBox.SelectedDataItemsChanged event to respond to item selection changes. Use the ChangeSource argument property to identify the action that caused the selection change.

ComboBox/TagBox items can be selected/deselected in two ways: UserAction, ParameterChange. ListBox item selection can be changed in three ways: UserAction, ParameterChange, ApiCall.

Refer to DxComboBox.SelectedDataItemChanged, DxListBox.SelectedDataItemsChanged, and DxTagBox.SelectedDataItemsChanged event descriptions for examples.
