The following table lists which characteristics need to be defined via the Data property for specific delegate types.
|Delegate Type||Characteristics to Return|
|VerticalGridCustomBindingGetDataHandler||A list of the requested data columns to be returned from a custom model. Starting position is specified by the VerticalGridCustomBindingGetDataArgs.StartDataColumnIndex property, and the number of columns to return is defined by the VerticalGridCustomBindingGetDataArgs.DataColumnCount property.|
|VerticalGridCustomBindingGetSummaryValuesHandler||A list of summary values calculated for each summary item within the VerticalGridCustomBindingGetSummaryValuesArgs.SummaryItems collection.|
|VerticalGridCustomBindingGetUniqueHeaderFilterValuesHandler||A list of unique values from a data field specified by the VerticalGridCustomBindingGetUniqueHeaderFilterValuesArgs.FieldName property.|
