Customized widget can easily be bundled with UDTT context data. A technical developer does not need to do any coding. If a widget needs to be bundled with a DataField type data, a technical developer must define a dataName type property named dataName. If widget needs to be bundled with Collection type data, a technical developer must define a dataNameList type property named dataNameForList. UDTT runtime assigns the value of the specified Context field to this attribute.
