Hello Roel,

After investigating setting delay for Tooltips issue and doing some research, it has been determined to be a product idea. You can suggest new product ideas for future versions (or vote for existing ones) at <http://ideas.infragistics.com>.
Submitting your idea will allow you to communicate directly with our product management team, track the progress of your idea at any time, see how many votes it got, read comments from other developers in the community, and see if someone from the product team has additional questions for you.
Remember when submitting your idea to explain the context in which a feature would be used and why it is needed as well as anything that would prevent you from accomplishing this today. You can even add screenshots to build a stronger case. Remember that for your suggestion to be successful, you need other members of the community to vote for it. You can also link back to this thread for additional details.

Alternatively, this can be achieved by setting Timers. If the Mouse is not moved for specific number of seconds then you can set a timer to go off after that time. Once it goes off you can show the tooltip. If following this approach, timer has to be removed in the control's Leave event in order to not show the irrelevant tooltip for any control.

Thank you in advance to submitting your product idea.

Please let me know if I may be of further assistance.
Sincerely,
Sahaja Kokkalagadda
