Description
Represents the data in a field component.
Data.DB.TBlobField.Value inherits from Data.DB.TField.Value. All content below this line refers to Data.DB.TField.Value.
Represents the data in a field component.
Use Value to read data directly from and write data directly to a field component at run time. For example, use the Value property to affect the contents of a field that is not Visible.
Note: For BLOB fields (Data.DB.TBlobField), the Value property is equivalent to the AsString property. The string data (Delphi) or AnsiString (C++) type can store binary data as well as text. Thus, even BLOB fields for nontextual BLOB types such as
ftGraphic
orftTypedBinary
can get or set their data using a string (Delphi) or an AnsiString (C++).
