Each dock panel can be associated with an image using its DockPanel.ImageIndex property. When a panel is within a tab container, its associated image is displayed in the corresponding tab. If the auto hide feature is enabled for the panel, the image is displayed within the label which corresponds to the panel.
The Images property accepts the following image collections:
- ImageCollection - Supports image transparency.
- SharedImageCollection - Supports image transparency. Allows you to share images between controls within multiple forms.
- System.Windows.Forms.ImageList.
