Description

Retrieves parameter values from the provider.

Call FetchParams to initialize the Params property with the current parameter values on the provider's dataset. FetchParams does nothing unless the provider's dataset can supply parameter values.

Note: At design time, you can fetch parameter values by right-clicking the client dataset and choosing Fetch Params.
Warning: If the provider is on a stateless application server, the values returned by FetchParams can be changed at any time by other clients. To obtain output parameters from a stateless application server, use the Execute method instead.
