Clears the contents of all fields for the active record.
Syntax:
procedure ClearFields;
Description:
Call ClearFields to erase the current contents of all fields for the active record. If the dataset is not in either dsInsert or dsEdit state, ClearFields raises an exception.
If a SetKey operation is not under way, ClearFields recalculates all calculated fields, and generates an OnDataChange event on the data source component associated with the dataset.
