I would look into the use of a Repeater with Selection enabled to do this in an efficient way.
Else you can overlay a hidden button on top of the Gauge which feeds the link to the web-frame
The biggest challenge you have going this route, is the fact that you have to somehow come up with some client side logic using the expression widget/validation widget and some parameters to get only 1 final result to feed into the web frame.
So the repeater is a much better way to go.
There may be some other solutions possible
Thank you for your help.
Unfortunately the repeater isn't the way I'm looking for. As for the hidden button, it is a good way, but it canceling the responsiveness of the mash (by default, I may have to use this way).
Is there a possibility to create a new gauge widget with an extension of clicking by a SDK?
