`public procedure TMasterParamsDataLink.CopyParamsFromMaster(`
`CopyBound: Boolean`

CopyParamsFromMaster calls TParams.CopyParamValuesFromDataset, passing it the master dataset: it provides the parameters of the detail dataset with their new values. If CopyBound is false, then only parameters with their Bound property set to False are copied. If it is True then the value is set for all parameters.

## Errors

If the master dataset does not have a corresponding field for each parameter, then an exception will be raised.
