Is there a way to display tooltips on an image that is dynamically created. The image is a dynamically created chart that has multiple points and on mouse over on a specific point I need to show additional information via a popup.
I’m using a web forms .net 4.0 and using the System.Drawing and System.Drawing.Imaging namespaces.
If your only output is a flat image, you could try adding a
<map>to your page and set the ‘title’ attribute of each<area>to your tooltip value.You can learn more about creating maps here: http://www.w3schools.com/tags/tag_map.asp
Essentially, you’re defining regions of your image as hot spots.
