Thanks for your update. We are glad to hear that the problem was resolved.
Query: why isn't the ToolTip control in the help.syncfusion.com for ASP.net? I had to use different control from the dropdown to post this thread because it is not in the list.
Currently we don’t have tooltip support for ASP.NE. We have planned to implement this feature in our upcoming main release Volume 3 2016 release.
Disclaimer: The date for the feature implementation is tentative and not a commitment on our parts.
