Throws:
Setting this property to true when the node doesn't have any children, will cause the node to expand anyway and request the child nodes from the server.

Throws:
When AllowHtml is set to true, the text can contain HTML content. If the text contains new lines (CRLF) but doesn't contain HTML elements (at least one "<") all CRLF are automatically substituted with " ".
Initiates the editing of the tree node label.
Throws:
Copies the tree node and the entire subtree rooted at this tree node.
Collapses the tree node.
Collapses the tree node and optionally collapses its children.
ignoreChildren
true to leave the child nodes in their current state; false to collapse the child nodes.
Collapses the tree node and all its children.
Cancels the editing of the tree node label.
cancel
True to discard the edited value.
Ensures that the tree node is visible, expanding tree nodes and scrolling the tree view control as necessary.
Expands the tree node.
Expands all the child tree nodes.
tree
handle
Returns the number of child tree nodes.
includeSubTrees
true if the resulting count includes all tree nodes indirectly rooted at this tree node; otherwise, false.
Removes the current tree node from the tree view control.
Toggles the tree node to either the expanded or collapsed state.
Updates the component on the client. Overridden to repaint the tree view in design mode.
All wisej components implement this interface.

: Returns a value indicating whether the tree node is in the selected state.
: Returns the last child tree node.
: Returns or sets whether child nodes are sent to the client the first time this node is expanded.
This option sends less data to the client and speeds up the creation of tree nodes with many child nodes. It can be used in conjunction with the property .
