How to set Custom images for expand/collapse (+/-) signs in the TreeViewAdv?

Platform: WinForms |
Control: TreeViewAdv |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014

 

The standard +/- signs for the expand/collapse buttons in the TreeViewAdv can be replaced with the custom images by setting ImageList to the newly added NodeStateImageList property of the TreeViewAdv

By setting some particular index of default image for expand/collapse button in the DefaultCollapseImageIndex and DefaultExpandImageIndex ,all the ParentNode can be displayed with default Images for expanding and collapsing actions.

Each Parent Node's +/- signs can be set with different images ,by setting the TreeNodeAdv's CollpaseImageIndex and ExpandImageIndex.Single click on the image expands or collapses the current node.
