Where do you access the image for the node expand/collapse image (see screenshot below)? I've looked for an image property and tried CSS, but cannot find it. Thanks for your help in advance.
Hello dbishop9,
As David mentioned above there is currently no property available that can be used to change the images from the Visual Studio designer.
What you can do is to change the image that is displayed for expand/collapse with your own image with similar size.
The image name is “igdt_Plus.gif” and it is located in the “ig_res/Default/images/” folder located in your project.
Note that if you use different styles for your tree you will have to change the same image for all of the styles in the project.
Let me know if you have other questions.
