The TreeView server control does not provide client-side functions such as the number
of checked items on the TreeView or changing the colors of the checked nodes. All
these activities have to be done using customized JavaScript. In this demo I perform
the following JavaScript manipulations:
- Count the number of checked nodes
- Suppress the ToolTip display when the mouse if hovered over the checkbox
- Change the style of the first node
In another demo in this section, "Custom TreeView", I perform more JavaScript manipulations
by creating a custom server control instead of using the provided TreeView Control.
