Property Value

Type
string

Remarks

The FieldName property addresses the field in a data controller to which the item is linked. The field itself can be accessed via the Field object.

When FieldName is assigned, the ValueTypeClass property defining the type of value this item represents is set automatically based on the dataset field type. This ensures the grid performs properly when accessing, sorting and validating item values.

The field type determines the default editor used to edit the contents of the item. The following table lists the default editors corresponding to field types. This correspondence is specified by the DBRepositoryItemClasses array declared in cxEditDBRegisteredRepositoryItems unit:

Field type	Default editor
ftBoolean	TcxCheckBox
ftCurrency, ftBCD, ftFMTBcd	TcxCurrencyEdit
ftDate, ftDateTime	TcxDateEdit
ftTime	TcxTimeEdit
ftBytes, ftVarBytes, ftBlob, ftFmtMemo, ftParadoxOle, ftDBaseOle, ftTypedBinary	TcxBlobEdit
ftMemo	TcxMemo
ftGraphic	TcxImage

For items connected to other fields, TcxMaskEdit is used.
