public event EventHandler SelectedIndexChanged
'Declaration Public Event SelectedIndexChanged As EventHandler
'Usage Dim instance As RasterImageList Dim handler As EventHandler AddHandler instance.SelectedIndexChanged, handler
public: event EventHandler^ SelectedIndexChanged
For single selection RasterImageList controls (i.e. when SelectionMode is set to RasterImageListSelectionMode.Single), this event occurs whenever there is a change to the index position of the selected item.
In a multiple selection RasterImageList control (i.e. when SelectionMode is set to RasterImageListSelectionMode.Multi), this event occurs whenever an item is removed or added to the list of selected items.
To determine which items are selected in the RasterImageList control, use the SelectedItems property to access the RasterImageListItemCollection.
You can also determine which items are selected in the control by enumerating all the Items and checking the RasterImageListItem.Selected property.
You can create an event handler for this event to perform tasks whenever there is a change to the selected items in the RasterImageList control.
