The changes introduced with the Kendo UI R3 2016 release enable you to determine if the
valueMapper must resolve a value to an index or a value to a dataItem. This is configured through the
mapValueTo option that accepts two possible values -
"dataItem". By default, the
mapValueTo is set to
"index", which does not affect the current behavior of the virtualization process.
