Returns the number of panes at the root level of a splitter.
An integer value specifying the number of panes at the root level of the splitter control.
A splitter control's client-sdie functionality allows the panes at the root level to be accessed programmatically. The GetPaneCount method is used to determine the number of the root splitter panes maintained by the splitter's ASPxSplitter.Panes collection. This method can be used together with the ASPxClientSplitter.GetPane method when iterating through the splitter's root panes to determine its upper bound.
