I've mentioned here that I calculate a -ve coordinate so I can click on the checkbox portion of a TreeItem to change its Checked state. I can't set Checked directly:General changes/Features
Added a warning when performing mouse/pointer actions outside an element's boundaries caused by a relative location
Is there a better way of changing the Checked state of a TreeItem that I'm missing?Setting attribute 'checked' failed on element '{TreeItem:Site B}'.
The operation is not supported.
Is there a way of suppressing this warning?
Or should I just calculate a coordinate relative to the Tree control rather than the TreeItem?
