Description

Controls the ability to change a TField value.

Use the CheckUpdatable property value to control whether FireDAC should raise an exception when the application tries to modify the field value in an inappropriate state. The default value is True. 

This is normally prohibited when:

• The dataset is not in the dsEdit, dsInsert, dsSetKey, dsCalcFields, dsFilter, dsNewValue, dsInternalCalc state.
• The dataset state is dsEdit, dsInsert and TField has ReadOnly = True and FireDAC.Stan.Option.TFDUpdateOptions.CheckReadOnly = True.
• The dataset state is dsSetKey and the field is not indexed.

An exception is raised when CheckUpdatable is set to True and one of the above conditions is not met.
