How to update map without page refresh

Previously (v1.0) I used a timer included in the updatepanel to send the results of a database query to the map. However in V2.0 the inclusion of the timer in the updatepanel results in the following error:

Error 1 Type 'System.Web.UI.UpdatePanel' does not have a public property named 'Timer'

and

Error 2 Content ('</asp:Timer>') does not match any properties within a 'System.Web.UI.UpdatePanel', make sure it is well-formed. 

If I place the timer outside the updatepanel, a page refresh results everytime the timer ticks.

Please advise.

Fixed this.

I accidentally removed the ContentTemplate tags.

If I place the timer within the

contenttemplate tag it is OK.
