Properties

• LoadingMessage is a string that displays next to the node being expanded. The node needs to have expand mode equal to ServerSideCallBack or WebService.

• The position of the loading message relative to the node text is determined by the LoadingStatusPosition property. Its possible values are as follows:

• BeforeNodeText

• AfterNodeText

• BelowNodeText

• None to suppress the loading message.

• When the PersistLoadOnDemandNodesproperty is True (the default), nodes populated through load-on-demand are persisted on the server automatically.
