I have label within the update panel.
In that label, I have a pie chart, which do not have a hover effect.
Response.Write(mychartdata.getImageMap("imgMap3")); does the hovering effect, but it stops dropdown onselected event.

C#

lblReferedByBelow.Text = "<img border='0' usemap='#imgMap3' src='pieChartServer.aspx?Legends=(" + strHeading + ")&Vals=(" + strValues +
                    ")&Expload=(" + strExpload +
                   ")&fontface=" + "verdana" +
                   "&fontsize=" + "8" +
                   "&LS=" + "10" +
                    "&RS=" + "10" +
                    "&TS=" + "10" +
                    "&BS=" + "10" +
                    "&pieRatio=" + "70" +
                   "&bar3dratio=" + "8" +
                   "&EoffSet=" + "35" +
                    "&imgFormat=" + 0 +

Response.Write never works properly when UpdatePanels are used.

To resolve this, move the result you wish to achieve from the Response.Write into its own control on the page, and place it inside an update panel.

Then in code behind, instead of Response.Write, perform the steps you need to get the data, then call UpdatePanel.Update(). Ensure the new update panel attribute "UpdateMode" is "Conditional".
