How do I selectively prevent diagram shapes from being clickable? (Read 4202 times)

	Hi, I would like to present a diagram on which the user cannot click on any links, and only on certain shapes. I am using ImageMap mode. I have read the following post, but I want to prevent the user from even seeing the mouse pointer change when they hover over a shape on which I do not want them to click. When users see that, they will believe that they can in fact click on it. Is there any way to prevent the shape/link to not be clickable in the first place (and not show the mouse pointer change to a hand). Any suggestions? Thanks Jim PS: Here's that other post I mentioned: http://mindfusion.eu/Forum/YaBB.pl?num=1339696488/1#1

	Hi, Try handling the CreatingAreaElement event like this - Code void diagramView_CreatingAreaElement(object sender, MindFusion.Diagramming.WebForms.CreatingAreaElementEventArgs e) { if (e.Item is DiagramLink) { e.Attributes["onmouseover"] = "document.body.style.cursor = 'default'"; e.Attributes["onmouseout"] = "document.body.style.cursor = ''"; } } Theoretically you should be able to set Attributes["style"] = "cursor:default", but it did not work for area elements in my test. I hope that helps, Stoyan

	Hi, I realize this post is a bit old, and I must apologize for not thanking you earlier for the suggested approach. It does work, with one exception. Although the mouse pointer changes, the ToolTip on the links does not always show when you hover them. I have found that this depends on the LinkTextStyle value. The following does NOT show the tooltip: LinkTextStyle.Rotate This one DOES: LinkTextStyle.MiddleSegment Since most of my links use the first style, any ideas on how to get the tooltip to show? Thanks in advance Jim PS: I've included 2 screenshots that demonstrate the issue.

	Hi, This shouldn't have anything to do with TextStyle, but if you change it to MiddleSegment for all links, do the tooltips start to work? The Tooltip value is set as a title attribute for the <area> element in the image map, and the control expects that the browser will detect the <area> under mouse pointer and show its tooltip. If you click on links that do not show tooltips, do you get the LinkClicked event raised for them? Stoyan

	Stoyan, Looks like the LinkTextStyle is not the issue. I changed them all to be MiddleSegment with the same results. I have attached a screenshot showing which links display their tooltips (yellow) and which ones do not (red). Let me know if there's more that you need. Thanks Jim

	It's because of the arrowheads color then If you distinguish between kinds of links using arrowhead color and text style, is there any other property you can think of set to different values, e.g. Locked, or is there any difference in the tooltip texts?
