Specifies the value indicating if a tree node is in a Checked, Unchecked or Indeterminate state.

Remarks

By default, you can switch Checked and Unchecked state by clicking on the tree node. The tree node switches states without affecting parent or child nodes's CheckState. The tree node will never enter Indeterminate state.

You can specify EO.Web TreeView to automatically switch parent or child nodes CheckState by using AutoCheckParent, AutoCheckChildren and AutoUncheckChildren properties. The above properties allows you to create a friendly user interface for selecting/deselecting a group of options.

By specifying the above three "Auto" properties, clicking on a tree node will affect parent or child nodes's CheckState and parent node might enter Indeterminate state if not all of its child nodes are in the same state.
