How to remove node?
Hi,
What is the correct way to delete a node?
I tried with node.remove or tv.selectednode.parent.nodes.remove(node). they worked but the structure is broken.
The node position and other columns is indented one level to the right (nodes position are changed)
The icons now overlay node names.
.
Thanks you!
Hi jamin,
Thank you for reaching out.
The methods you mentioned for removing a node—using node.Remove() or tv.SelectedNode.Parent.Nodes.Remove(node)—are correct.
However, based on the information and image reference you provided, it seems like the node removal is affecting the structure, causing nodes to become indented incorrectly, and icons to overlay the node names.
We tried to replicate this issue on our end by creating a simple sample and removing nodes in the same way. In our tests, the nodes were removed correctly, the structure remained intact, and the icons were updated properly without overlapping the node names.
For your reference, we have attached a simple sample. Please take a look at it.
To assist you further, could you please confirm if the issue occurs specifically when removing nodes at runtime, where the icons overlay the node names? Additionally, could you provide more details on the actions performed that led to the nodes’ positions changing? Knowing the product version you’re using would also be helpful.
We appreciate your cooperation and look forward to your
response.

Pretty long Santhosh,
anyway I hope to get it fixed before I get a related bug and have to wait another month..
If this is related to treeviewadv, please check that too as it seems these 2 controls are related.
Hi jamin,
Thank
you for your feedback. We understand your concerns and will make sure to
address this issue in TreeViewAdv as well. We’re actively working on this and
will notify you as soon as the fix is released. We appreciate your patience and
understanding in the meantime.

Hi jamin,
We would like to let you know that Essential Studio Weekly
NuGet packages (V27.1.51) has been published in nuget.org with
the fix for the issue “Node text overlaps the image icon after nodes are
removed at runtime when horizontal scrollbar is disabled”. Please let us
know if you have any concerns in this.
Root cause:
Based on our implementation, when we remove nodes at runtime, the HScroll
property is updated. However, in this scenario, the HorizontalScrollbar value
was not updated correctly, which led to the reported issue. We have now updated
the HorizontalScrollbar value based on HScroll property.
