Thank you Cetin, but I have the ImageURL just like your code and it works fine. But when a user clicks ON the ImageMap in the datalist you have a "hotspot" defined that sends them to a URL using the hotspot.NavigatioURL property. In this case, when they click on the image of a hotel in the datalist I want to send them to the hotel's homepage.

When I try to databind the hotspot's NavigationURL property with this code:

HotSpotMode="Navigate" NavigateUrl='<%# Eval("GoToURL") ' />


I get this error:

Error 1 Databinding expressions are only supported on controls. System.Web.UI.WebControls.RectangleHotSpot is not a control.

So I don't know how to set the NavigateURL that the imagemap click goes TO.

I've spent a lot of time on this with no luck. Obviously I must be able to use an ImageMap in a simple datalist in ASP 2.0 to link to another site!

Any ideas?
