Example: TcxCustomDataController.BeginLocate, TcxCustomDataController.EndLocate
The following code searches the record containing a specific value of the EmpNo field in the dataset displayed by a tvEmployee view of ExpressQuantumGrid. The TDataSet.Locate method used for searching is enclosed by the BeginLocate and EndLocate methods. It prevents the data controller from the full data reloading which usually occurs when using Locate.
