public virtual HotTrackSelectMode HotTrackSelectMode { get; set; }Property Value
| Type | Default | Description |
|---|---|---|
| HotTrackSelectMode | **SelectItemOnHotTrack** | A HotTrackSelectMode value that specifies how items are selected. |
Available values:
| Name | Description |
|---|---|
| SelectItemOnHotTrack | If item hot-tracking is enabled, an item is selected when hovering over it with the mouse. |
| SelectItemOnClick | If item hot-tracking is enabled, an item is selected when clicked. This option is not in effect if the BaseListBoxControl.HighlightedItemStyle property is set to HighlightStyle.Standard. |
| SelectItemOnHotTrackEx | The same as the HotTrackSelectMode.SelectItemOnHotTrack option plus the following. If item skinning is enabled via the BaseListBoxControl.HighlightedItemStyle option, the BaseListBoxControl.SelectedIndexChanged event is raised each time an item is hot-tracked. In HotTrackSelectMode.SelectItemOnHotTrack mode, the BaseListBoxControl.SelectedIndexChanged event is raised only when clicking the item. |
Remarks
To enable item hot-tracking, set the BaseListBoxControl.HotTrackItems property to true, and ensure that multiple item selection is disabled (see BaseListBoxControl.SelectionMode). The HotTrackSelectMode and BaseListBoxControl.HighlightedItemStyle properties specify the way hot-tracked items are selected.
The following describes selection specifics when item hot-tracking is enabled.
The currently selected item can be obtained from the BaseListBoxControl.SelectedItem property. Additionally, depending on your logic, you can handle the BaseListBoxControl.SelectedIndexChanged event to respond to selection changes. However, note that this event is not automatically triggered during item selection in certain cases, as shown in the table below.
HighlightedItemStyle value | Default/Skinned | Standard | |||
