You might try hosting TreeView controls as in this example:

https://mindfusion.org/_samples/Trees.zip

The TreeView.Expand and the fc.BoxModifying event handlers recalculate the arrow end points positions so they keep pointing to their respective TreeView node. You might have to handle more events like that, e.g. the ones related to TreeView scrolling.

If you allow your users draw links between TreeViews, then you will have to add some code to find the TreeView node with which an arrow should be associated.

I hope that helps,

Hi Ganesh,

Unfortunately FlowChart.NET cannot draw in the windows of hosted controls, so arrows cannot start directly from items of the TreeView. If you need that, you could use a tree of Boxes as in the first sample, but that would require a lot of work to implement scrolling.

I guess this could be done by using tables too, if our developers extend the "header rows" feature to allow for deeper hierarchies (right now only two-level hierarchies are possible). However our list of customer-requested features is quite long at this time, we might need 2-3 months to get to that.
