TcxDBBlobEdit Class

Represents a data-aware control used for displaying and editing BLOB data from a data source.

Declaration

TcxDBBlobEdit = class(
    TcxCustomBlobEdit
)

Remarks

The TcxDBBlobEdit class represents a control used for working with BLOB (Binary Large OBject) data obtained from a data source. The BLOB editors are capable of storing and editing two data types: memo and image data. The visual representation of the type of data stored within an editor is defined via the BlobPaintStyle property. The type of edited data is determined via the BlobEditKind property. This property value affects the entire editor functionality.

Since the BLOB data is just a sequence of bytes, the BLOB editor needs exact instructions about data interpretation. For instance, if the BLOB editor is connected to a data source field containing graphic data, then the BlobEditKind property must be set to bekPict.
