TDataSetAdapterMemoField Class

The TDataSetAdapterMemoField represents a memo field in a dataset.

Pascal
TDataSetAdapterMemoField = class(TCustomDataSetAdapterMemoField);
C++
class TDataSetAdapterMemoField : public TCustomDataSetAdapterMemoField;

Add TDataSetAdapterMemoField as a child of a TDataSetAdapter component to represent a memo field in the dataset associated with the dataset adapter. TDataSetAdapterMemoField represents a single field from a database table, and enables server-side script to refer to or update that field's value. When generating an HTML form or grid displaying dataset fields, server-side script calls the TDataSetAdapterMemoField to retrieve the value of the dataset field and write the value to the HTML content. When executing a TDataSetAdapter action, the TDataSetAdapterMemoField is responsible for validating and updating the dataset field. 

TDataSetAdapterField supports several properties that can be used in server-side script. These include: 

Value, which is the current value of the field. 

DisplayText, which represents the current value of the field as a text string. 

DisplayStyle and InputStyle, which indicate the type of control that should represent the field value in HTML forms. 

DisplayLabel, which provides a text label that can be used to label HTML controls that represent the field. 

Required, which indicates whether the field requires a value. 

Visible, which indicates whether HTML forms should include a control for this field.
