		string	bindingPath )

inlineprotected

Gets the real source helper method.

Parameters

source	The source.
bindingPath	The binding path.

Exceptions

ArgumentNullException bindingPath is null.

◆ GetRelativePath()

◆ ParseRelativeBinding()

virtual ? BindingExpression Csla.Xaml.PropertyInfo.ParseRelativeBinding ( BindingExpression? sourceBinding )
