BaseStyleControl Class
Serves as the base for controls that cannot be used as in-place editors and supports a common style management mechanism.
Namespace: DevExpress.XtraEditors
Assembly: DevExpress.XtraEditors.v24.2.dll
Declaration
public abstract class BaseStyleControl :
BaseControl,
ISupportAppearanceObjectPropertiesFilterRemarks
The BaseStyleControl class is the base for all DevExpress controls that cannot serve as container controls or in-place editors. It supports a common mechanism used to manage control appearance, paint style, and hint settings. Paint style and hint setting mechanisms are inherited from the BaseControl class. The BaseStyleControl class, in turn, introduces the BaseStyleControl.Appearance property, which has appearance settings such as background and foreground colors, font settings, and content alignment used to paint the control.
Tooltips
DevExpress controls support regular and super tooltips. If the ShowToolTips option is enabled, tooltips are shown when the mouse pointer hovers over the control.
Use the following properties to specify a regular tooltip’s content:
- ToolTip — A regular tooltip’s text. If the text is not specified, the tooltip is not displayed even if the title is specified. You can use line breaks in regular tooltips. Use the AllowHtmlTextInToolTip property to specify whether to parse HTML tags in the text. HTML tags allow you to format the text: size, style, hyperlinks, etc.
- ToolTipTitle — A regular tooltip’s title. If the title is not specified, it is not displayed.
ToolTipIconType — A regular tooltip’s predefined icon. Use the controller’s IconSize property to specify the image size.
To display a custom image in all regular tooltips, use the controller’s ImageList and ImageIndex properties.
To display a custom image in a specific regular tooltip, handle the BeforeShow event. Use the ImageOptions event argument to assign a raster or vector image to the processed tooltip.
Use the SuperTip property to assign a super tooltip to a control. Enable the AllowHtmlText property to use HTML tags in the super tooltip.
To replace regular tooltips with super tooltips, set the ToolTipController.ToolTipType property to SuperTip. The controller automatically converts regular tooltips to super tooltips. To access this property, you can use the DefaultToolTipController component or a custom controller assigned to the ToolTipController property.
