Not able to select the Node below a link

Hi,

We are having one issue with link shape.
We are having a node of type MindFusion.Drawing.Rect,  with Width=12 and Height=6 , and when we are having a link passing through the middle of that shape, we are not able to select that node.

I have set the shadowOffsetX and Y to zero. Still not fixed.

Any workaround for this?

Thanks
Kiran B

Hi,

Try setting Diagram.LinkHitDistance to a small value, e.g. try with 1.

I hope that helps,
Stoyan

Hi Stoyan,

Its not fixing the issue.
Also i don't see the LinkHitDistance in client side object only server side has this property.


The real issue is the node is showing the anchor point while mouse over the node, but when clicks the selection happens for the link.

Thanks
Kiran B

There is Diagram.setLinkHitDistance method in the JavaScript API. Setting a small value means you will need to click more precisely near a link to consider that a hit on the link, and that should let you select the node by clicking near its borders, but not within the specified distance from the link. Displaying anchor points is not an indication that clicking there will select the node, it only shows where a new link would snap if you start drawing a link from that node.

Hi Stoyan,

I don't see that property in the Diagram in js side.
I am using version 1.6.

Thanks

Hi,

I can see it listed in the online help here, which we haven't updated to 1.7 yet, and its help topic should have been imported from the source code:
http://www.mindfusion.eu/onlinehelp/mvcdiagram/index.htm?M_MindFusion_Diagrammin...

Are you trying to call it and getting an error message? Note that's a member of the Diagram class, and not of DiagramLink.

Hi,

That can be related to either $find or setLinkHitDistance. If the canvas loads correctly and other functions work, it's probably the latter. Make sure you have copied latest diagramming.js to your project, and clear the browser cache in case it keeps an older version of the script.

I hope that helps,
Stoyan

setLinkHitDistance exists in version 1.6 from what I can see. Check if you aren't using a script file from an older release. The diagramming.js I get with v1.6 installation has ‎November ‎08, ‎2013 creation date.
