Its complicated, i have a user control (.ascx ) and i have a Xceed Chart on it. then i have many tabs with different configuration for the chart, like axis,legends,titles,series, so the user set the configuration then click in a button named Apply, to set this configuration to the chart. one of this configuration are the tooltips, but they dont work if i dont place the code of the HTMLImageMapResponse, when the page load at the beginning everything is good, but then when i make a change and then apply them to the chart, after the postback, the page throw me that javascript error.
