I want to know how i do to put a loading message gif in the loading message?
And how i do for the treeview is limited, example: my treeview gets 6000 datas and i want that the client user navigates trought the navigate bar like the iexplorer...
The gif will be shown if the node has expand mode = ServerSide or ServerSideCallBack.
In order to get vertical scrolling you need to set the Height property of the RadTreeView control.
