Thank you for writing back.
I am not familiar with the implementation of the UserControl
that you have. However, note that using controls in tree view nodes may slow down the scrolling and will cause visual glitches as they do not support clipping. It is recommended to use only elements as it is demonstrated in the sample project. A better option would be using custom editors. Thus, you can construct the desired editor and activate it for the respective node.
I hope this information helps. If you have any additional questions, please let me know.
