    I have enabled hints on a Kendo Grid and they are all showing fine except the hint on one column.  The column in the schema is "Message".  As you can see from the attachment when you hover over that column you see a small oval shaped balloon instead of a hint. 

    I have removed the attributes for that column declaration in the grid to stop if from showing a hint at all but the strange balloon shows anyway.

    Each row has a details row that can be seen when the user clicks the right facing arrow in the first column.  In the div that shows the message column is shown.  So maybe that has something to do with it.

     

    Any suggestions would be welcome.

     

    Thanks

    Hello Reid,

    I can think of two cases in which the Kendo UI Tooltip will show:

    1.) The Tooltip is configured to show on HTML elements that have no "title" attribute
    2.) The Tooltip content returns an empty string

    -  configure the Tooltip's filter to skip certain elements
    http://docs.telerik.com/kendo-ui/api/javascript/ui/tooltip#configuration-filter

    Or

    - check the content and toggle visibility

    An example of how to show content dependent on its length can be found here:

    http://docs.telerik.com/kendo-ui/controls/layout/tooltip/how-to/show-on-length-condition

    Should this not resolve the problem, please send a code snippet with the grid configuration (here or in a support ticket) so we could assist further.
