The DevExpress ASP.NET MVC Card View can automatically truncate cell values if they don't fit into cell width. To indicate that the text is clipped, the grid displays an ellipsis ('...').
By default, this functionality is disabled, set the SettingsBehavior.AllowEllipsisInText property to true to enable it.
In this demo, this funcionality is enabled. Uncheck the corresponding check box to disable it. Point the mouse cursor over an ellipsis to display a tooltip with the full text.
