Remarks

Use the BaseLayoutItemOptionsToolTip.ToolTip property to provide a tool tip shown when the item’s caption is hovered over with the mouse pointer. The AllowHtmlString property enables HTML formatting in the tooltip. If this property is set to Default, the feature is controlled by the ToolTipController.AllowHtmlText global setting.

The code below enables HTML tags for a particular item, and specifies a formatted tool tip. For the complete list of supported tags, see HTML Text Formatting.

layoutControlGroup2.OptionsToolTip.AllowHtmlString = DevExpress.Utils.DefaultBoolean.True;
layoutControlGroup2.OptionsToolTip.ToolTip = "Enter a <b>valid</b> address";

The result is shown below.

You can also override the HTML formatting setting for a particular item when handling the ToolTipController.BeforeShow event. For this purpose, use the ToolTipControllerShowEventArgs.AllowHtmlText property of the ToolTipControllerShowEventArgs object passed as a parameter to the event handler.
