Flex 2.3 Pop-Ups

JoshJones1 — Mon, 18 Apr 2011 01:17:09 GMT

I am trying to use the new Pop-Ups feature to allow for a image to be displayed when I mouse over a shapefile outline. I currently have a raster dataset stored in the shapefile attribute table and I am trying to figure out how to have the image pop up when it is clicked on or moused over.

Is this possible? Does anybody have any other ideas on how to best use the new Pop-Up widget to reach this goal? I have about thirteen separate regions within the shapefile and I have a different image subset associated with each of the regions, which is why I loaded all of the rasters independently.

Thanks Robert for the very quick and informative response.

I am very new at using ArcServer. I am an intermediate GIS student with no experience at coding. Would I have to implement that code in Flash Builder, or how exactly would I go about implementing that app code? Up to this point all I have done is edit the existing widgets that are present in the flexviewer folder.
