Setting ImageListAdv as the imagelist of TreeViewAdv

[typod]

Hi,

I might be doing something silly, but is there a reason I can't set an ImageListAdv as the imagelist for a TreeViewAdv control.  I only seem to be able to select the standard image list control.

I am trying to sort out DPI scaling in my simple app and wanted to use ImageLIstAdv to host different icons based on the DPI of the system but for some reason it doesn't appear in the drop down list.

Hi Typod,

Thanks for reaching out to us. Can you please confirm is this the issue you are facing?

Thanks for the response.  Here is what I am seeing, but funnily enough I am also getting the error in the screenshot you mentioned.  In the drop down list I would expect to see ImageListAdv alongside the standard imagelist.
