I have an asp.net site that uses a dropdown listbox to select 1 of 6 different images to be displayed at one time. Changing the image is working fine. But I need to define and use a different set of coordinates for each image. One image could have as few as 5 regions, while another could have up to 100. The coordinates will be hardcoded but I can't seem to figure out how to load different sets of "PolygonHotspot " based on which image is displayed. I thought it was going to be as easy as assigning an ID to 100 different hotspots, then turning them off or on and defining the coordinates based on the image name. That seemed like the perfect solution .. until I found out that the PolygonHotspot doesn't have an ID property.
Any help would be GREATLY appreciated! Please email me at bry at herp dot com
Thank you in advance,
Bryan Mohr

Just for reference (even though this doesn't work), here is the code that I was hoping would work: -
Protected Sub cbImageCombo_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cbImageCombo.TextChanged
-
Dim strImageName As String = cbImageCombo.Text
-
Dim strImageText As String = strImageName
-
-
strImageName = "~/Images/" & strImageName.Replace(" ", "_") & ".JPG"
-
imImage.ImageUrl = strImageName
-
imImage.AlternateText = strImageText
-
-
' First Make all Hotspots inactive
-
HS001.HotspotMode = "Inactive"
-
HS002.HotspotMode = "Inactive"
-
HS003.HotspotMode = "Inactive"
-
-
' Next activate the defined hotspots for the currently selected image
-
If (strImageText = "Spinal Cord Side") Then
-
HS001.HotSpotMode = "PostBack"
-
HS001.AlternateText = "Top Vertebrae"
-
HS001.Coordinates = "118,16,127,11,135,4,142,4,154,11,155,16,154,17,143,15,139,15,132,22,118,17,118,17"

-
HS002.PostBackValue = "Second Vertebrae"
-
End If
-
-
If (strImageText = "Skeleton Front") Then
-
HS001.HotSpotMode = "PostBack"
-
HS001.AlternateText = "Skull"
-
HS001.Coordinates = "120,14,126,7,134,3,138,3,146,6,151,11,154,17,154,27,152,39,148,41,148,49,142,53,132,53,125,49,125,43,124,39,121,35,121,32,119,28,119,16"

HS001.AlternateText = "Lateral Deltoid - Right"

Hello,
I have a simple problem: mark a list of defects

I think the best way to do it is to select a single

the button, and the second when he releases it).
Those two points are going to be send to the web
application (i.e. with AJAX) and saved in a database.
