Pivot Grid > Custom Move Validation
This sample uses CTP (Community Technical Preview) features. The API and behavior may change when these features are released with full support.
This sample shows how to configure custom move validation with the Pivot Grid and the Pivot Data Selector. When using a custom validation function, dropping items to the columns is forbidden. Also any hierarchy that contains the word "Seller" in its name will not be accepted by the drop areas in the Pivot Grid and the Data Selector.
