Hello Francesco,

Currently our igRadialGauge control does not have tooltips. You can log a product idea at our product ideas site. the Product Ideas site allows you to suggest new product features, new functionalities in existing products and controls, and even request new controls and products altogether. Members of the Infragistics Community then vote for the features and suggestions they want to see added to the products, resulting in the most popular features bubbling up to the top.

When planning new releases, our Product Management team will look at the most popular features and use your feedback to prioritize upcoming work.
