Need to "draw" line (mouse click/drag) on a graphic displayed on ASP.NET page and save changed graphic.
Posted on 2008-06-18
Hello Experts! I've searched this one up and down and can't find an easy solution.
1. When the ASP.NET 2.0 page is loaded it will display a default graphic (how - I don't care).
2. The user of the page must be able to use their mouse (pointing device) to click and drag to form lines. I mean the same as drawing a "freehand" type of line on a piece of paper - NOT click point A then move mouse to point B and click again and have a straight line between the two points.
3. The default graphic is now modified (unless you have a better idea) and must be saved in the DB (I can handle that). When the next user opens the page they are presented with the default graphic. When the returning user opens the page they are presented with their modified graphic.
Please let me know if any of this doesn't make sense. The solution has to work within a MasterPage and live pleasantly with AJAX 1.0. I'll be on tonight watching for Q and A. I'm looking for quick and dirty on this one. Thanks in advance!
