Gets or sets the image list that is used to indicate the state of the TreeView and its nodes.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The state images displayed in the TreeView are 16 x 16 pixels by default. Setting the ImageSize property of the will have no effect on how the images are displayed. However, the state images are resized according to the system DPI setting when the app.config file contains the following entry:
<appSettings> <add key="EnableWindowsFormsHighDpiAutoResizing" value="true" /> </appSettings>
When the CheckBoxes property of a TreeView is set to true and the property is set, each TreeNode that is contained in the TreeView displays the first and second images from the to indicate an unchecked or checked state, respectively. You should set the property before you add nodes to the TreeView to prevent state images being shown at design time for nodes that do not have a state image set.
