Client-side event lost on callback
posted

I´m attaching a double-click client-side event on an dynamically created gauge. At first time works ok but after a callback on the update panel where the gauge is, there is no more client-side doble-click.

Any idea?

    the following code worked for me.  clicking the button inside the refreshpanel caused an async postback, and the gauge doubleclick handler was still intact.  is this what you're trying to do?
