Description

Enables changing the ending value for an existing range.

Call EditRangeEnd to bring the dataset to the dsSetKey state and change the ending value for an existing range. 

After the call, the application can modify indexed fields. To iterate through them, use the IndexFieldCount and IndexFields properties. Optionally, the value of the KeyFieldCount and/or KeyExclusive properties can be edited. 

After assigning a new ending value, call ApplyRange to activate the modified range.

Example

FDQuery1.IndexFieldNames := 'CUST_NO';
FDQuery1.SetRangeStart;
FDQuery1['CUST_NO'] := 100;
FDQuery1.SetRangeEnd;
FDQuery1['CUST_NO'] := 200;
FDQuery1.ApplyRange;
......
FDQuery1.EditRangeEnd;
FDQuery1['CUST_NO'] := FDQuery1['CUST_NO'] - 1;
FDQuery1.ApplyRange;
