TcxGridDBChartItemDataBinding Class

An object which links a Chart View item with a dataset field.

Declaration

TcxGridDBChartItemDataBinding = class(
    TcxGridChartItemDataBinding
)

Remarks

Every Chart View item (a category or a series) uses a DataBinding object to link to a dataset. Generally, the data binding is used to determine the type of the value. The value type is identified by the ValueTypeClass property. The ValueTypeClass determines the manner in which the data is represented (as a string, integer, date, Boolean, etc.). In bound mode, you can associate an item with a data field in a dataset by setting the item’s DataBinding.FieldName property. The ValueTypeClass is assigned automatically based upon the field’s type. The ValueTypeClass and ValueType properties also provide ways in which to implement unbound items in data-aware Views.
