Lines between treeview items

Hi,

 

Is there a plan to support lines between treeview items as available in radtreeview?

 

radTreeView1.ShowLines = true;
radTreeView1.LineStyle = TreeLineStyle.DashDot;
 
Without this it is very confusing to the end user what the connections between open items are.
 
Regards,

peter

Hello Peter,

Yes, we are committed to supporting lines between the nodes in the TreeView. The feature request is marked as Unplanned which means that this is a valid enhancement for the component. We prioritize public requests based on many factors such as popularity (the number of Votes), how many scenarios can be achieved with a single feature, our internal vision of developing the Telerik UI for Blazor, and more. 

That being said, at that point, I am not able to provide an estimate timeline for the implementation of this feature request.

Hello,

are lines for the TreeView component of Telerik UI for Blazor still unplanned? Our customer has demand for this feature where the parent-child relationships are visualized with connecting lines as can be seen in the following.

In this regard, I'd appreciate your thoughts on this question https://feedback.telerik.com/blazor/1448095-expanded-items-handling-feedback-requested - we are considering changing the way item expansion is pre-set and we'd love to hear from you.

Sure, but it works well enough for now :) functionailty wise this all works fine except for the visibility of parent -> child relationships.

TBH this all connects to GoJS anyway and so all I really need is a UI element to generate some json to push to GoJS, I was trying to reduce the complexity (and mainatin the look and feel (this is just part of a much larger application)) of GoJS -> Blazor actions by pushing from Blazor -> GoJS for diagram generation.

Thank you Peter.

Editing and comlex logic is something that might be more suitable for a TreeList component which is on our roadmap (maybe as early as R3 2020): https://feedback.telerik.com/blazor/1406094-treelist-control, so you may want to Follow that too.

Have attempted to solve this programtically with text, will work on a more complete solution to have the lines extend up to the top level parent, if I come up with something simple that fulfills the requirement, I will share here.

Hello Peter,

I am sorry that the current design does not fit your project needs. It has been successful in our Kendo UI for jQuery suite for almost a decade, yet I also see value in the grid lines, which is why this request is open. An implementation is not "just a few lines", though, as treeviews have a complex structure and this needs to account for a lot of cases, it might even need extra HTML elements in the component rendering, it is not just a few border CSS rules.

The problem is that your tree view isn't really a tree if it doesn't have branches, it's currently very difficult to see how treeview items are connected when you get more than a few branches on the lower levels. This is a major usability issue for my project, I'm not sure why this is considered a 'large scale effort' when it's just a few lines on the page.

Hello Peter,

This is a rather large scale effort that needs planning, research and prioritization. Up until now, we haven't had that request and there aren't immediate plans for that. You can see what its state is in the underlying themes repo here. Once this becomes available as a feature in the themes, it has to be enabled through the Blazor TreeView component itself.
