We have a similar example among our small set of
WebSharper.D3 samples. What you have looks OK, what do you have for dragstart?
I couldn't find any use of the dragstart event in those samples. Where you referring to the CompaniesGraph example?
In any case, you can see the issue in http://try.websharper.com/snippet/user4207/0000CG. When a node is double-clicked the event handler is triggered, but when a node is dragged then the event handler is not triggered.

Built with WebSharper |
I'm trying to translate https://gist.github.com/mbostock/3750558 into F#, and I can get everything to work except for the
dragstartevent handler (https://gist.github.com/mbostock/3750558#file-index-html-L35):var drag = force.drag().on("dragstart", dragstart);In the WebSharper API
force.Dragis aWebSharper.JavaScript.Function, which doesn't provide an.Onmethod. I've also tried to treat the dragstart event in the same way as a click event:someSelectionOfForceNodes .Call(force.Drag) .On("dragstart", dragstart) // dragstart handler not shownbut in this case the dragstart handler is never called.
What am I missing?
